Author: admin Release time: September 28, 2016 Number of visits:

From the production process of small and medium-sized concrete mixer, if the materials crushed by ring hammer crusher and reversible hammer crusher are used for brick making and cement production, the mixture still needs to enter the mill for fine crushing, and the single stage fine crusher can achieve one-stage crushing and then meet the particle size requirements. The machine-made sand production line is mainly composed of vibrating feeder, jaw crusher, impact crusher, vibrating screen, sand making machine, belt conveyor and centralized electric control equipment. Because artificial sand is mechanized production, there are fixed production sites and relatively perfect organization and management, personnel quality is relatively high, and these are the most natural sand production enterprises lack. Among them, mobile, fixed and brick making machine combination production line is the better combination equipment. The amount of construction waste in China has accounted for more than% to 40% of the total amount of urban waste, generating 400 million tons of new construction waste every year. Mobile chassis has standard lighting and braking system, which conforms to the standard, hydraulic opening, fast and convenient! Hydraulic support legs are used to facilitate lifting and installation, combined design of silo is adopted to greatly reduce the transportation height, and solve the problem of construction waste. Recently, the fifth mechanical construction waste treatment equipment sent to Chengdu has been put into operation. The technological process of Liming mechanical construction waste crusher occupies the construction waste treatment market in Inner Mongolia, and its technological process is: construction waste collection____ -Crushing (construction waste crusher) and screening____ -Calculation of quantity and reasonable ingredients______ Stirring______ -Embryo molding cutting processing EPS board - overall product compounding - solar energy conservation - product stacking - Inspection of ex factory technology, building waste into environmental protection and energy-saving building bricks. Artificial sand can be widely used in concrete, mortar and products. At present, the annual output of sand and stone in China is about 3 billion tons, which basically meets the needs of construction industry and related aspects. If the ore block fed into the crusher is too large or too much ore, or often falls into the non crushing material (metal block), the wear and damage of the machine will be accelerated. 2. The vertical stroke of movable jaw is relatively large, which is favorable for discharging, especially for viscous and wet materials. During the 12th Five Year Plan period, with the adjustment of economic structure and the upgrading of industrial structure, the proportion of real estate in GDP will gradually decrease. There are many kinds of nonmetallic deposits, such as phosphate deposits, salt deposits, asbestos deposits, graphite deposits, diamond deposits and gem jade deposits, etc., and they are widely distributed, which makes it possible for us to make use of them in large quantities. The sand and gravel production mode and production efficiency have been greatly improved. It has greatly enhanced the setting strength and solid structural strength of cement concrete. With the development of Metro dawn and large-scale buildings, natural sand has been in short supply, and the strength and other properties of machine-made sand are superior to natural sand. This kind of crusher is widely used in mineral processing, building materials, silicate, ceramics and other industrial sectors because of its simple structure, reliable work and the ability to crush hard materials. Therefore, the radial clearance will increase the vibration of the bearing in the passband. Determine whether the actual discharge and output meet the requirements, and ensure that the bearing temperature rise does not exceed 35 ℃, the crusher should work smoothly without severe vibration, and all fasteners should be reliable. The mobile crushing station of counterattack type is ready to start. The main engine of YDS mobile crushing station is a special impact crusher for limestone. The limestone crushing technology combined by the R & D Department of Liming Mining Machinery Co., Ltd. determines the key wear-resistant parts of limestone, such as limestone hardness, characteristics, linear speed of hammer head, feed particle size, moisture content of stone, etc__ -Service life of hammer head. The new construction mixer adopts automatic microcomputer control, and a series of processes such as feeding and mixing can realize man-machine dialogue and improve production efficiency. It not only reduces the pollution degree in the crushing process, but also leads the new direction change of crusher equipment. 2. The product has good grain shape and high quality aggregate. The advantage of the impact crusher is: the impact crusher is a good application. (4) The bearing seal at both ends of crushing roller is not good, and its service life is only 1 year. The water pollution in some river basins and sea areas is serious, and the atmospheric haze phenomenon is prominent in some regions and cities. In many areas, the discharge of main pollutants exceeds the environmental capacity. The impact plate angle of impact crusher can be adjusted to ensure that the material is in the right angle when repeatedly impacted between the impact plate and the rotor, which can effectively improve the crushing efficiency. And Zhengzhou Liming mining machine has made positive contributions to promote the development of domestic construction waste recycling and treatment, and promoted the realization of zero waste of construction waste recycling technology in China, and made significant progress!. In fact, construction waste is not helpless. If it is effectively treated, it can be used as renewable resources, bringing significant economic and environmental benefits. Improving construction quality and prolonging the service life of buildings should be the primary task of energy conservation and emission reduction in the field of Engineering dawn, and should be the higher responsibility of every dawn person. High quality sand and stone materials must be used in the concrete of dawn degree, and the higher the concrete grade is, the more strict the requirements for sand are. The inherent defects of natural sand can not meet the requirements. Therefore, it can meet the requirements of concrete modernization. It is possible to control the particle size, gradation and material by manual sand washing. In 2000, China produced more than 500 million tons of cement and 700 million cubic meters of concrete. With the development of society and the progress of science and technology, water conservancy, construction, transportation and other industries need this product. It is used to build water conservancy dams, bridges, power stations, high-rise buildings, overpasses, cement pipes, etc., and the market is good.

Small and medium-sized concrete mixer truck Zhengzhou Liming mining machine stone production line is the use of rock, sand, pebbles, limestone, basalt, granite, pebbles and other raw materials, through the vibration feeder, jaw crusher, impact crusher (sand machine), vibrating screen, belt conveyor and a series of production equipment process, according to different departments It is widely used to meet most of the market demand. However, at present, there are only more than 20 enterprises engaged in the recycling of construction waste in China, and the national recycling rate is only about 5%. However, the recycling rate of construction waste in EU countries is more than 90%, and that in South Korea and Japan is more than 97%, which is really embarrassing. During this period, the center arrested 9 construction waste thieves. The safety door is designed to replace the vulnerable parts and become a substitute for the new type of impact rupture. Even the construction waste buried in the past has become treasure. No unit or individual is allowed to mix domestic waste and hazardous waste with construction waste, and shall not deliver construction waste to individuals or units engaged in transportation of construction waste without approval. A charging system shall be implemented for the disposal of construction waste, and the charging standards shall be implemented in accordance with the relevant provisions of the state, the province and the municipality. The municipal construction waste competent department should input the approved clearing and transportation information into the digital monitoring system for supervision. The first is to actively carry out scientific and technological innovation. The annual investment of mining enterprises for scientific and technological innovation is no less than 1% of the total output value of mining enterprises. There is no place to pour construction waste in the city. Like other big cities in Beijing, Shenzhen, as an economically developed city, is also facing the problem of garbage siege. The sand and stone crusher developed by Zhengzhou Liming Mining Machinery Co., Ltd. is divided into jaw crusher, impact crusher, cone crusher, construction waste crusher and sand making machine. Nowadays, crushing equipment manufacturers pay more and more attention to the R & D and production of efficient and energy-saving crushing machinery. Perhaps, you will ask, why is it equipped with fine sand recovery? Because some customers have reported to us that in the wet sand production line, a lot of fine sand has been washed away by the sand washing machine. These wastes are buried in the ground, which will cause groundwater pollution and directly endanger the lives of the surrounding residents. 3、 China's construction waste treatment and resource utilization technology is backward, urban construction waste treatment mostly adopts direct landfill treatment, which not only occupies land but also pollutes the environment. Capital investment is not a problem. Although the initial investment is larger, it can recover the cost in one year. Yuhang's annual demolition volume is more than 5 million square meters, and the construction waste generated is about 4 million square meters, which has become a persistent disease of urban management. Zhengzhou Liming Mining Machinery Co., Ltd. If necessary, please reprint it! Liming mine crusher, counterattack crusher, vertical impact crusher, jaw crusher, I wish the industry a healthy and comprehensive development! At present, the standardized construction waste recycling treatment plant in the eastern suburb of Kunming has been put into use, and there are 12 mobile brick making machines that can handle construction waste on site. In addition, the standardized construction waste recycling treatment plant in the western suburb is currently installing equipment, which is expected to be put into operation next month. By then, Kunming's annual treatment capacity of turning construction waste into treasure will reach To 4.8 million tons. China's high-speed railway is speeding up at dawn, which provides broad development space for construction machinery, crusher, stone production line, sand and stone equipment, etc., and has been paid more and more attention by these industries and related industries. Construction waste occupies 1000 mu of land a year, which is a shocking number. According to the calculation that 1 mu of land is occupied by 10 000 tons of construction waste, the annual construction waste needs to occupy nearly 1000 mu of land. The comprehensive utilization project of construction waste resources of Huawei building materials Co., Ltd. eats residual bricks and gravel, spits out new environmental protection bricks, and can regenerate 800 tons of construction waste in a day. After several years of development, we have rich construction waste treatment experience and construction waste treatment technology. The dawn of high-speed rail will drive the industrial upgrading of relevant regions. As the R & D unit of construction waste treatment equipment, Zhengzhou Liming Mining Machinery Co., Ltd. hopes that the environment of Zhengzhou will be cleaner and better, and will contribute to the urban Liming of Zhengzhou. One million tons of construction waste is utilized on site, and South University of science and technology has become the first zero emission demonstration project of construction waste in China. This is the first construction waste treatment equipment in Liming District, with an annual treatment and consumption of over 2 million cubic meters of construction waste, which can basically meet the treatment needs of Zhengzhou and its surrounding areas, and fully guarantee the natural resources and urban living environment of Zhengzhou and its surrounding areas. The harmful substances contained in construction waste and its leachate will change the physical structure and chemical properties of the soil, affect the nutrient absorption and growth of plants, affect the activities of microorganisms in the soil, and destroy the ecological balance of the soil. Because the quality of the equipment is directly related to the quality of the project liming, according to the different grades of Liming highway and railway, the quality requirements of sand and stone materials are also very different. It is an inevitable choice for the gravel plant to improve the quality of sand and stone materials as much as possible, among which the selection of crusher and sand making machine is very important. The traditional way to deal with construction waste is to bury or pile up, but this unscientific treatment method not only occupies land, but also pollutes the environment, and even damages surface water and groundwater. The mobile construction waste treatment system has four characteristics: movable, small dust, low noise and less land occupation. The annual output of construction waste in China has not reached several billion tons. At present, China's construction waste recycling has a certain technical foundation, whether it is laboratory research or market application have certain results, recycling technology can make construction waste zero waste. In recent years, with the rapid development of China's economy, all walks of life are developing. The scale of mining and construction industry is gradually expanding, and various metal and non-metallic mining industry has set off a new climax of dawn production all over the country. The sand used in most areas of China's economic dawn is natural sand. With the decrease of natural sand, natural sand resource is a kind of non renewable resource in a short period of time. People began to pay attention to artificial sand, and the price of natural sand is rising, people believe in artificial sand. Construction waste treatment technology has been mature, but there are only a few successful cases in China. Liming mining machine is one of the very few. With the introduction of construction waste crusher of Liming mining machinery, it has caused great economic and social effects in the market. At that time, the conditions were not perfect, and the brick making machine had not been used, so the construction waste could only be crushed and screened to produce recycled aggregate. Crusher in the work to consume a huge amount of energy, due to the operation of heat, sound, vibration and other functions, consumed a lot of energy. Liming Mining Machinery Co., Ltd., as a modern mining machinery manufacturer integrating R & D, production and sales, has seen this point. While expanding sales channels, it has also continuously innovated and developed new crusher products and strictly controlled the quality of design, development, production and after-sales service. Liming mining machinery construction waste crusher has achieved a considerable market in China. We all know that Liming mining machine has good quality and long service life. Old customers also introduce new customers to Liming mining machine. With the rising of the dawn of subway in China, there are many profit industries. The sand and stone materials needed in the dawn of high-speed railway rely on the crusher equipment of mining machinery to solve the problem. If the pace of development is slowed down, the crusher industry will be impacted to a certain extent. At present, there are a lot of idle tailings in China. If the new development of mineral processing technology is used to recover these tailings, it is no less than building a new mine. With the advent of the information age, enterprise informatization strategy has been put on the agenda. During the 12th Five Year Plan period, the central government, local governments and enterprises have invested more than 10 billion yuan in manufacturing information technology projects.

At present, the average mileage of concrete mixer truck in China is only about 5.8 cm in the world. It can be used to transport bulk materials with large proportion and high grindability, and the chain wear is small. According to the speed difference of hopper operation, it can be used to transport materials with large grinding property. Zhengzhou Liming Mining Machinery Co., Ltd. is aware of this point, after years of research, independent research and development of construction waste treatment equipment. The main components of construction waste include: soil, slag, waste steel, waste iron wire and various scrap steel fittings, metal pipeline waste, waste bamboo and wood, sawdust, shavings, packing boxes and bags of various decorative materials, scattered mortar and concrete, broken bricks and concrete blocks, yellow sand, stones and block stones scattered in the process of transportation. These materials account for about 80% of the total construction waste According to statistics, before 2000, the total amount of tailings produced by China's mines was 5.026 billion tons, including 2.614 billion tons of iron ore tailings and 2.109 billion tons of main non-ferrous metals,. The amount of gold tailings is 272 million tons, and other 31 million tons. In addition, the mine tailings storage also occupies a large number of farmland, woodland, and has a certain degree of environmental pollution. In recent two years, China has been advocating the issue of environmental protection and energy conservation. In strict accordance with the relevant policies of energy conservation and emission reduction, private enterprises are encouraged to aim at environmental protection and energy conservation projects, 2009. From January to may, there were more than 200 enterprises for comprehensive utilization of tailings crushing, with a total investment of nearly 20 billion yuan, which effectively promoted the progress of comprehensive utilization of mineral resources. For tailings crushing and recycling, Zhengzhou Liming Mining Machinery Co., Ltd., a famous R & D manufacturer of mine machinery crusher, mill and sand making machine, aims at tailings recovery and crushing process,. Take the necessary and efficient technology to produce the large crusher equipment. At present, the annual output of construction waste in the city is more than 1 million tons, which is mainly disposed by landfill, which is easy to cause land waste and environmental pollution. It is a series of crushing equipment, including various types of special crushers, stone materials, sand production line equipment, etc., to crush and reuse the mine tailings and processed stone waste. The advantage of machine-made sand is that a large number of waste ores, tailings and pebbles can be reused. On the other hand, the quality of sand produced by crusher is generally good, which can meet the requirements of various grades of concrete, such as asphalt concrete. 2、 On load test run. 1. The crusher shall not have periodic or significant impact and impact sound; 2. The larger feed particle size shall meet the design requirements; 3. The bearing temperature rise shall not exceed more than multi degree centigrade after continuous operation for 8h; 4. The processing capacity and product particle size of the crusher shall meet the design requirements; 5. There shall be no obvious movement between the adjusting seat and the rack seat. If any unsafe phenomenon is found, it should be replaced in time. When there is oil stain on the drive belt or wheel, wipe the oil with a rag; 4. Check whether the protective device is in good condition. 5. When the discharging equipment stops, the feeding should be stopped in time, otherwise, the impeller will be crushed and the motor will be burned. There are two kinds of artificial sand production technology: wet sand production process and dry sand production process. The machine sand production line of Liming mine has the advantages of high automation, low operation cost, high crushing rate, energy saving, large output, less pollution and simple maintenance. The manufactured sand meets the national construction sand standard, and the product has uniform particle size, good grain shape and reasonable gradation. 2. The user should install protective equipment on the V-belt according to the specific situation of the site before operation. 6. When the machine is running, if there is abnormal vibration or noise, the feeding should be stopped immediately. After the materials in the box are exhausted, stop the motor immediately, stop the machine for inspection, and continue to run after troubleshooting. As an industry player, liming mining machine is constantly improving in product research and development, and has carried out a number of technical innovations for the traditional jaw crusher, which makes its design more reasonable, crushing ratio larger and service life longer, especially in the design and production of large jaw crusher, liming mine has been at the domestic level. According to the firmness and durability test of manufactured sand, it is shown that the firmness of machine-made sand is slightly worse than river sand, but it still reaches GB /. T。 There is no problem in the use of the excellent product index of 141684293 standard in ordinary concrete. However, when used in concrete components which are often subjected to friction and impact, in addition to admixtures, it is necessary to control the ratio of cement to sand, the crushing index of sand and the content of stone powder.
