Relationship Between Technology and Building Waste

With the accelerated pace of Chinese modernization, a lot of construction wastes are produced, Disorderly dumping phenomenon can be found everywhere ,it is understood that the garbage dumping will not only take up a lot of land, but also serious pollute the environment, the accumulation of a large number of construction waste will destroy the soil structure, causing the surface settlement. In addition, the building construction waste glue, paint, paint or difficult biodegradable polymers containing harmful heavy metals in these wastes were buried in the ground, will cause groundwater contamination, direct harm to surrounding residents life.
With the continuous advancement of science and technology, the value of construction waste(such as the waste produced by hammer crusher, sand making machine) was excavated, according to experts, the reason why it is called the construction waste is that  these wastes are not effectively subdivided processing. Construction waste are actually change the physical properties of the building materials, the event that the classification and use of construction waste will likely become a gold mine in the eyes of the vision of building materials. Is true that there are some companies and even individuals began to turn its attention to this "gold mine".
Currently, construction waste resourceful utilization has already gotten the attention of the national people , during the two sessions, the members have proposed the Construction Debris legislation, strengthen the management of China's urban construction waste. According to Mr. Zhengzhou Dingsheng Engineering Technology Co., Ltd. engineer: "construction waste after the initial cleaning, sorting out recyclable steel and wood, then masonry, cement concrete blocks broken into aggregate after the height of construction waste disposal equipment R & D, After screening, to remove impurities, the formation of a certain size requirements of building materials. "

It is reported that the applied scale of recycled aggregates  is wide,they can be used as wall plastering materials, planting soil Backfill materials, brick-making industry, recycled concrete aggregate and recycled.

the recycled aggregate brick can be idvided into the   following kinds: the ground material eco-permeable bricks, pouring permeable brick, the permeable Road tooth brick three ecological permeable bricks are widely used in square, sidewalk, slow lane, open square, garden , slope protection, protecting group, highways and overpasses.
Meanwhile, planting soil regeneration is carried out   through  the construction waste sorting, and then crushed into powder, sludge as a raw material, add other kinds of wastes, including sewage treatment plant sludge, wineries and food plant residues, peat soil trace elements, according to the proportion of a certain quality, stirred by mixing together, in addition to the natural characteristics of the soil, with high fertilizer efficiency, breathable and water retention these characteristics.

A transition period, not too fast nor too slow, to combine the resources and environment of the society as a whole, and to develop an appropriate set of options. Goes something like this bird in a cage, Guan Yu can not Zhang Fei; life skills on people, Pig needed Wukong. Mean to constantly break the shackles of institutional reform and innovation, and a taste of the future direction of development, but also continue to strengthen risk management. In such a new kind of social environment, it is also to promote energy conservation.
Our company-as a crusher industry leader, and how to adapt to the pace of the times, the trend of the times, how do innovation and development?
The above problems are mainly reflected in the following aspects:
First . Product quality and security, due to the crushing machine widely used in many industries ,the requirements of the crusheris also increasing . Since we all know that according to the feeding and nesting size, the crushing operations are often divided into coarse crushing, medium crushing and crushing. Must be tough crusher performance, high frequency of use, smooth operation and fast, long life cycle, will not easily be eliminated.
Second, product innovation, crusher in order to improve competitiveness in the industry must be innovative, the mountain climbers Heavy done this, and done very well, with excellent quality, technical skills, dedication and technical personnel, advanced technology and equipment to improve the overall performance of the crusher (such as the impact breaker, hammer crusher), on the basis of the original, delving into the technical parameters, the survival of the fittest, the crusher step-by-step.

Bright Development Future of Crushing Industry

The earliest application of crusher is just limited in the mining industry, along with a better understanding of it as well as technical advances, the crusher industrial application range is very wide now , such as the process of vehicles scrap cars or electrical appliances, if matchedsorting equipment and conveyors are equipped , it can be easily automated handling and processing of scrap various industrial products, recycling of steel and non-ferrous metals and non-metallic material available.
As to the dominated crusher in the world, above nearly 7% are developed on the basis of the  United States Newell products , which is more representative of Germany Lindemann, Japan's Fuji and China mountain climbers Heavy. Since the successful development of new crusher in Europe in the 1980s, the manufacture of the crusher structure design, manufacturing processes and materials continue to improve and improve. Such as the German company O & K new impact breaker machine, made a special design of the crushing chamber, rebound, metal ore material may pop up. This is also the foreign crusher application characteristics, paid great attention to the composition and structure of the material.
With the rapid development of the domestic economy, crusher industry's status in the economic and social  are also rising,which has also become essential in many industrial production  . We all know that the crusher is widely used in mining, metallurgy, building materials, road, railway, water conservancy and chemical industry and many other sectors. Common crushing machines are winnowing mill, hammer crusher, impact breaker, roll crusher, compound crusher. Jaw crusher (jaw crusher), having large crushing ratio, uniform particle size, simple structure, reliable operation, easy maintenance, operating costs and economic characteristics. PF-I series impact breaker can process materials side length is 100 to 500 mm, the compressive strength is up to 350 MPa, great crushing ratio, cubic particles advantages of material was broken; PF-II series impact breaker machine, suitable for crushing hard materials, such as cement crusher, with a production capacity of the material advantages of small particle size.
When dealing with a variety of metals, non-metallic mineral raw materials and construction materials in the production process, in order to improve the efficiency of the grinding operation, to achieve energy saving and emission reduction targets at home and abroad have developed various types of crushers, such as a hammer, to fight back type, the fastest growing anti-vertical shaft, especially hammer crusher material uniformity, high efficiency, simple structure and light weight, easy operation and maintenance.
Duo to a variety of reasons, the foreign crusher industry develops slowly  since the 1980s,   due to less investment  in the home industry, there have not much development, making this market appears blank, less new equipment, the supply can not meet the demand of the market , so the developemt future is broad.

Problems of the Crusher Accessories Production

In China, the development of wear foundry industry shows the situation of multiple small workshop enterprise and without leading enterprises, combined with the current state support for the project and the future development the field prediction , the wear-resistant castings enterprise development of our country is woeful. According to expert analysis, the wear-resistant casting industry in China has  the following mainly problems:
1, the confidence  crisis  between customers and manufacturers of the foundry industry are gradually increases. There are many well-known wear-resistant casting manufacturers reflect that many customers consulting accessories would ask such a question: "Your hammer is cast or forged?" As we all know, casting hammerhead is wearable than forging hammerhead , casting the hammerhead price is slightly higher, but the life of forged hammerhead 2 times and more. Therefore, some unscrupulous manufacturers to take advantage of the customers of the casting the hammerhead and forging hammer to discern common sense weakness, forging hammer to flicker customers, and earn high profits, resulting in the lack of trust  in the entire casting industry  .
2. Many manufacturers can not produce wear parts such as  hammerhead production by themselves , most of them  purchased from the pruchasers , but advise customers that they are able to produce, and then pocketing the difference. A cement plant in Zhejiang work a few days ago from a factory in Zhengzhou processing batch DPC2022 high manganese steel hammer found in the use of the hammer hammer with its former appearance or wear life without distinction, the only The different procurement manufacturers and price is different from the original has been purchasing from a factory in Shanghai hammerhead price than processing hammerhead per kilogram over two money expensive and salesman, and later happened to mention it, they would understand, originally a factory in Shanghai is simply not able to produce casting hammerhead, has been procured from a factory in Zhengzhou, pocketing the difference.
3, there are little plants which can do the rotor repair .  Good crusher need to have the excellent rotor, the rotor is the core part of the crushing machine, once the rotor breaks, the entire production will not be able to operate, and the crusher rotor replacement is a larger expense, many manufacturers will choose to hammer plate The end disk cracking rotor surfacing repair. Especially Fujian, Zhejiang region due to the materials and working conditions, crusher rotor repair business more, however, in addition to our company, the domestic companies which is able to undertake the crusher rotor repair business are very few,and far from satisfying market demand.

The Application Field of the Mechanical Sand

In recent years, the qualified natural sand resources are on the less , so the artificial sand gradually became the main source of construction work . Currently, our Beijing Olympic project, Xiaolangdi reservoir Baoquan reservoir, Hongqiqu reservoirs, Gezhouba Tianwan River Power Plant, these key national projects all use the artificial sand to prepare the concrete, and both its construction sand and gravel bone material strict audit and inspection. In the existing engineering practice, the preparation of artificial sand from C10-C70 ordinary concrete and pumping concrete, configure a span prestressed concrete beam whose length is 64m.
However, if the mechanism of sand does not meet the requirements, the construction of key projects, housing, highways, high-speed railway will appear a variety of engineering quality problems, so as a mechanism of sand production enterprise, responsibility must be the production of high-quality qualified mechanisms of building sand sales to the market, prepared by high-performance concrete used in construction, so can largely avoid the bridge tatami floor back down "event, visible, high-quality artificial sand can configure high-performance concrete to increase the life of the housing, roads, railways and other infrastructure projects and key construction projects.
What problems should we pay attention to when we prepare the high-quality sand ? In the crushing system of sand making production line, the traditional simple jaw breaker, cone crusher, fine jaw breaker can not meet the requirements of the the senior architectural spaces materials, because basalt gravel in flakiness and the internal cracks gravel contents are too high, production mechanisms sand quality are not good too . So, to produce better quality mechanisms sand ,the counterattack crusher must be used as a secondary crusher or sand making machine as the last one broken shaping. Generally lagging behind the entire domestic Sand production technology, the lower the yield, the higher prices, so choose  hammer breaker is the most common, such as: Shandong, Hubei, Inner Mongolia, Gansu, Guangdong and other regions, and these market gravel machinery, sand production line equipment manufacturers, many kinds of hammer breaker our company produced have the features of  advanced technology, stable equipment performance and large market share . A lot of sand and gravel production enterprises use the configuration sand production line of our company , it is true that the sand production efficiency is high,the mechanical sand podwer produced by this machine is low, gradation and quality are super .

2. The artificial sand product specifications are diverse to meet the different applications needs. Construction requires the particle size of gravel and sand are different , such as 1-3,2-4,3-6 and the other specifications, the PCX sand making machine our comapny produced  can produce different specifications qualified mechanism sand products , all of them  meet the needs of different construction applications.
3, The investment is relatively small, the cost recovery period is short, the  return rate is high  . Such as a sand and gravel production line whose daily output is 5000 tons, we only need to invest 15 million yuan , and from start building to put into production items, only 100 days duration will be able to make a profit producing benefits. The benefits of these advantages and benefits quickly are fuly confirmed by the long-term rock crushing plant experiences of our company,
4, Energy-saving and low consumption, low noise, more environmentally friendly. Accompanied with the rapid developmetn of economic construction, regional industrial development, the corresponding result is the deterioration of the ecological environment. energy saving and environmental protection are increasingly being paid attention by the government , enterprises, social , compared to the same kind products, the artificial sand production line our company produced not only have the advantages of excellent crushing rate, high production output, but also pay more attention to the environment friendly design, we adopt the totally closed design, reduce noise, install the dust removal devices,and  really achieve the purpose of  building green artificial sand production line.

There are alternative products of air classifier - JZF series air classifier machine,which mainly composed of the motor grader housing and extension round. Motor driven classification round   rotates at high speed (the speed can be arbitrarily adjusted) in the classification of housing,which forms a powerful centrifugal force in the grader. a mixture of gas and powder enters the inside of classifier wheel, under the effect of centrifugal force, a large or heavy particles which bears centrifugal force are left to the side wall of the classifier wheel periphery , and no longer subject to the influence of centrifugal force, naturally fall to continue crushing crushed the host or the whereabouts of the collection to the discharge port; small or light materials by centrifugal force, hovering inside the classifier wheel, cited wind effect by the induced draft fan is with the highest point of the smooth the pipes move to the next component is graded or collected. Frequency conversion adjustment the classification wheel speed can be adjusted to the size of the centrifugal force grader to separate the materials specified granularity purposes.
Installation, operation and maintenance methods
(A) Installation: check the machine , make sure that it is intact, no loose screws ,then we can  install  the machine. Grader should be securely installed on the basis of great poured concrete . The foundation designed should   have a very good supporting role to minimize the shear force on the screw.
(B) after learning the structure and working principle of the spiral classifier , it is allowed to operate the machine.

Security Production Rules of the Rotary Kiln

Whether the equipment( such as ball mill, impact crusher) falls into any category, production safety should always be placed in the first position. Rotary kiln production is no exception,the following is the rotary kiln production safety rules ,the related recommendations, and overhaul of rotary kiln Notations:
1, the rotary kiln maintenance. "Listed" repair system should be implemented, the striking "someone work" , "not to start "and so forth should be written on the card, cut off the power when using the machine, just in case.
2, the rotary kiln   stopped overhaul.
(1) must notify maintenance personnel of various parts to finish the tool, all personnels should stay away from working place, and recover the work permit before changing the rotary kiln.
②in case of unsafe conditions, the overhaul leader should be responsible for the danger accidents.
③ If the work permit did not receive completely and change the rotary kiln, the kiln turner should be responsible for the rotary kiln danger.
(4) after transferring the kiln properly, the "work permit" should be sent to the maintenance jobs at any time, this is to show that the rotary kiln is completed before the overhaul.
⑤ when the repair is completed, immediately  return the  "work permit", and  accept and commission the machine.
3.When checking or cleaning the coal warehouse, the operators  should not be less than two to avoid absorbing large quantities of pulverized coal and fainting, or to inhaled CO overdose which leads to nobody rescue.
4,  before starting the equipment, we need to get the permit.
5, overhaul equipment lights, prohibited use the 220-volt lights.
6. Rotary kilns, in addition to the operator and relevant staffs,  the remaining staffs have to leave the kiln, for preventing the severe burning pulverized coal, gas volume expansion backfire and burn people. 
7, the operating equipment can not be repaired: as to whether the device is in operation, we should not use the quiz method of contacting with the hands and feet, for preventing burning by  the running machine  .
8, non-electrician should not tamper with electrical equipments,   staffs are required to wear overalls, Ping cap.
9, when leathering or circling into the demolition kiln, high temperature shoes, gloves, masks must be wore to prevent the brick or kiln skin burns or bumps.
10, when the coal powder burn naturally outside the warehouse,  the method of watering can not be adopted,  because the  coal fineness is very fine, having liquidity, if we watering them, the coal powder will dispel, the fire then will be spread.

Usage and Characteristics of Modern Drying Equipment

Drying equipment (drying equipment) is a series of mechanical equipment  combination which is processed by certain technical means. Its main purpose is to dry the materials surface moisture or other liquids . The currently popular drying technologies are mainly UV drying, infrared drying, electromagnetic drying and hot air drying these four kinds . They all have their own characteristics, and are all widely used in all kinds of machineries equipment and food drying.
The application of the modern dryer (dryer)  machine:
This equipments are mainly used to dry the materials which have certain humidity or granularity in mineral process, building materials, metallurgy, chemical industry and other departments.

Significance of Vibrating Screen in Production Line

Cement production line vibrating screen: As the name suggests, it is a cement production line vibrating screen for screening (vibrating screen), in the cement production, we need to first crush the mature materials to 5mm by the   crusher, and then use the  mill for the next crushing . The most important is that this new process can improve output about 30%, and save electricity about 18%, so it is widely used by many cement producers. 
　　　
In order to assure that the mature materials size achieve to 5mm below, we need to select the materials whose size is larger than 5mm and re-crushing them. So the crushing machine and cement mill are necessary to equip the clinker vibrating screen, this screen machine can be used for raw material grading and screening equipment ,and also is essential in the former class equipment, cement vibrating screen is also a cement production processes of various cement packaging machine, due to high granularity level requirements of the finished product in the cement industry, the final inspection process is needed before the product packaging , cement vibrating sieve is used to screen cement powder and other materials in the agglomeration, foreign body, in order to guarantee the quality of the product.
Duo to the cement production line material strict size requirements, the level of material crushed having a direct impact on the reduction of the production costs. In the cement production line, after crushing the mature materials to 5mm below , and then sent them to the mill for the next crushing.  This can improve the cement mill station production   about 30%, saving electricity about 18% these substantial economic benefits. This new technology has been adopted by many manufacturers. In production , in order to ensure the granularity into grinding clinker, the vibrating screen are needed in the  crusher and cement mill.
According to the requirements of this process, the cement clinker vibration sieve we produced  adopted coarse and fine two layers of mesh, which having high screening efficiency, slagging, long life, low power consumption, small size, light weight these characteristics, but also because of its use of reliable installation, easy maintenance, clean up the debris and replacing the screen of the screen surface, damping spring,they  are very convenient and welcomed by users, this vibration sieve (vibrating screen) can be used not only the clinker sieve ,but also the other materials sieving.

Trend Analysis of Mine Feeding Equipment

Duo to the great importance Chinese government attaches the coal industry, Chinese coal washing career has experienced a rapid development, which both bring development to the feeding equipment industry space, but  also  the pressure of market competition. For adapting to this new trend and meeting the feeding machine requirement of the high quality ,efficient coal preparation plant, we suggest the following development trend:
[1] Emphasis on fundamental research,  strengthen research management. Basic research provide the basis of optimizing   product structure, improving   quality and reliability, reasonable selection and formulate  , and   promote the application of new technologies , new product development.
[2]  Accelerate the automation of coal preparation process monitoring and control technology research. Coal preparation machinery automation is the essential path to improve labor productivity,  ensure the safety of operations and reduce coal preparation costs  . Despite the  history of automation technology application is long,  there has been some technical imperfections, the introduction and application of automation technology in coal preparation plant is  also relatively slow. In today where the computer technology, sensor technology and artificial intelligence   develop  to a certain level, the feeding equipment automation process will be accelerated.
[3]  Perfect the existing equipment. Which is similar to the other industries(such as sand making machine industry), the application of modern technology in the feeding equipment gradually grows,   but  the existing feeding equipment will continue to use, and   continue to tend to perfection, because if we use the new technologies or the old-typed equipments only ,it is impossible to obtained marvelous results.
[4] Strictly control the environmental pollution. Environmental pollution is mainly caused by the feeding equipment noise and dust, so the focus of controlling environmental pollution is to control it in the limits prescribed in the national standards, and should try to applicate, research this new technology as long as possible, put the pollution to the minimum.
Large feeding equipments have the advantages of high efficiency and processing power, but the equipment's large-scale, standardized   and high reliability is also  its development trend . In recent years, the large-scale feeding equipment in the domestic coal industry has been widely used, there are certain issues, such as the technical parameters of the device called extensive,   affect the actual use, which requires further theoretical research and improvement, so it is best to further research and improve the current theories,only in this way, our feeding equipments can develop better and better.
