Analysis on installation and debugging points of concrete mixing station

In order to better deal with the large amount of concrete produced in the Great Wall, Great Wall Machinery through continuous development, research on the comprehensive utilization of concrete processing equipment, the relatively new mobile concrete mixing station has been successfully developed, and applied for the national construction patent, filling the blank of concrete resource treatment market, and in many places Yes, customer satisfaction is very high. Reduction is a priority measure to prevent concrete from polluting the environment. 1.7。 The application of mixer in feeding chamber. 1.11。 The discharge port of the mixer can be adjusted according to the specification. The user can change the number of gaskets in the rear support at any time according to the required particle size and the wear condition of the toothed plate in the operation, so as to adjust the discharge port and obtain the satisfactory granularity. There are several rows of disks installed on the main shaft of the Great Wall mixer. There are two rows of pin holes on the rotor disc. When the end of the hammer is worn, the pin shaft can be inserted into the outer ring hole to adjust the gap between the hammer and the screen bar. A sieve plate is arranged at the lower part of the rotor, and the particle size smaller than the sieve hole size in the material is stirred. The coarse particle size larger than the mesh size is discharged through the sieve plate. The resistance remains on the sieve plate and continues to be hit and ground by the hammer,. Later, it is discharged out of the machine through sieve plate. 1) Iron removal in ore feeding should be strengthened.

Concrete mixing plant installation and debugging key points analysis 5. The machine internal knock sound. Causes: non agitated materials enter into the machine; the fastener of lining plate is loose, and the hammer impacts on the lining plate; the hammer or other parts are broken. With the overall living standard of Chinese urban residents entering the later stage of well-off society, the pace of infrastructure construction of the great wall of urban residents is speeding up. The supply of natural sand for building materials has been unable to meet the demand of the Great Wall, and is now facing depletion. However, most of the sand making equipment manufacturers are small and medium-sized, and the production technology is still in the stage of gradual maturity, and the product quality of the equipment is uneven. There may be a considerable number of enterprises planning how to make money, and rarely consider customer demand and service comprehensively. The vast majority of railway, highway, bridge, hydropower station and other large-scale projects are located in deep mountains and valleys. The construction site is narrow, the construction period is tight, the concrete work quantity is large, the concrete construction intensity is high, and the quality requirements of sand and gravel aggregate are strict. Jincheng gold mine, Shanxi Province, carries out coarse and fine particle flotation after ore washing and classification. The practice shows that the ore washing can purify the mineral surface and enhance the floatability of useful minerals, which is conducive to the flotation of coarse-grained particles; ore washing classification can separate the fine-grained materials such as cement mixed into the ore, reduce the alkalinity of coarse-grained minerals, and improve the flotation effect of coarse-grained minerals; fine-grained minerals Although the concentrate grade is low, the recovery rate is high. The flotation recovery rate is increased by 2.32% on average, which can recover valuable metals and increase the gold production; ore washing can eliminate the problems of sticking the mixing chamber and blocking the screen hole, and improve the mixing and screening efficiency. China's subway is in the golden period of accelerated development. China's subway is one of the few successful industries in which "market for technology" is successful. The Chinese government has spared no effort to develop subway. The concrete solid waste enters into the mixer and is stirred by the high-speed rotating plate hammer installed on the rotor body. The mixed concrete material obtains a higher moving speed, hits the impact device installed above the rotor and stirs again, and then bounces back from the impact plate, collides with the rotor and the materials thrown out by the rotor strike, and after several successive impacts The concrete aggregate and reinforcement are completely separated, and the particle shape is very excellent, which is conducive to the recycling of concrete recycled aggregate. In front of the mixer, that is, between the feeder and mixer, we see a discharge belt, and a large amount of slag is screened out. 3. By changing the cavity type, the conversion of coarse, medium and fine crushing can be realized. At present, China's mixing machinery industry will usher in great development opportunities, mainly reflected in three aspects: first, China's mixing machinery market has become the focus of attention of equipment manufacturers, due to the rapid replacement of mixing machinery, especially the life of small mixers is only three or five years, the annual replacement of domestic blenders is about 20% of the total demand for blenders, which is mixing machinery Second, the Great Wall will provide a large number of concrete infrastructure in the process of rapid development.

To change the current situation of jaw mixer, it is required that the majority of equipment manufacturing enterprises should adhere to the investment of research and development funds, pay attention to the transformation of the production line, cultivate high-quality R & D and manufacturing talents, establish a perfect innovation incentive mechanism, etc., and improve and perfect the structure of traditional jaw mixer The new design theory of engagement angle is used to optimize the cavity shape of the machine body and reinforce the weak links. As the old mixer and mixer in Zhengzhou, the operation cost is simple and reliable. Due to poor lubrication and high temperature, the lubricating oil is easy to deteriorate, which accelerates the replacement and consumption of lubricating oil. In addition, carrier flotation is used. For most cement enterprises, how to improve the energy utilization rate of grinding process is one of the ways to save energy and reduce consumption on the premise of not affecting the mill output and increasing the production cost. Kaifu District urban management law enforcement team staff introduced that they generally imposed a fine of less than 200 yuan on individuals who dumped concrete, and imposed fines of more than 5000 yuan and less than 50000 yuan on units.
