West Pufeifo company, a C Corporation in the United States and China Shenyang Heavy Machinery Factory all the production of the product, the Shenyang Heavy Machinery Factory production of MPS series vertical roller mill technical performance table table 3-2. Figure 3 a 3 MPS vertical roller mill structure. Its working principle is: three pneumatic hydraulic mill roll (a drum) pressure in the annular groove of the disc motor through a transmission system drives the grinding disc to a certain speed rotation (20 to 30 RPM). Because of the friction between the roller and the roller, the roller rotates around its own axis. By connecting the three tie rods at the corner of the triangle pressure bracket on the machine base, the roller is applied to the roller. By the feeding chute into the material (particle size of 80 ~ 100 mm), grinding to 80% through 200 mesh sieve of fine powder, the millstone around the annular air inlet communicated with the hot air blowing, the upper part of the powder selecting device selected and coarse grain fall disc re grinding, fine powder the exit row dust collection device to collect for the finished product. Mill wind speed up to 60 ~ 80 meters / sec, and drying efficiency is very high. Recently, MPs type vertical roller mill was not only used for grinding cement raw material, pat successfully cement clinker grinding. According to West Germany, a cement plant with a new improved MPS3750C vertical roller mill grinding cement clinker, production of PZ35 (DIN standard) cement, output reached 40 tons / PZ45 cement production, output up to 78 tons / hour. Power consumption of grinding 25 percent less than the ball milling and grinding fineness is easy to control, the grinding of cement has high early strength. According to Reid grams (a - E - RedeKer). MPs type vertical roller mill in the cement raw meal grinding time, and set the metal wear rate was 5.7 g / ton, grinding disc lining board wear rate of 1.2 grams / ton, the system maintenance cost is only 0. Fourteen 2 dollars / ton. MPs vertical roller mill grinding cement raw material output has reached 500 tons /, grinding standard cement production has reached 150 tons /. It is expected that this vertical mill has a trend to develop in the direction of large scale. Figure 4 - 3 is a schematic diagram of the MPS vertical roller mill grinding device. The MPS mill under the same grinding. The grinding disc diameter is flat grinding, which makes the millstone around more stomata and under a certain wind speed have a larger volume of air, the mill pressure drop is lower, so you can save the power of the fan. On the other hand, there is a good heat transfer between the material and the hot air because of the large amount of ventilation, the material and the hot air. Due to MPS vertical mill grinding roller of a drum shaped, the grinding disc is provided with annular groove, so in our country, also known as drum and a slotted disc type hydraulic vertical roller mill.

quarry crusher is one of the main equipments of mine production, construction materials processing and polymer chemical production. It is widely used in the production and processing of all kinds of metal and nonmetal mines, chemical minerals, cement, building materials and other materials. In recent years, with the development of mining production and building materials processing, some new theories are proposed, which can be obtained by the user to be able to get more fine granularity and better block size in the crushing stage. In addition, with the emergence of the phenomenon of global mineral depleted, maintain or increase the of all kinds of metallic and non-metallic mineral production, processing ore quantity requirements will increase greatly, which of crushing equipment put forward higher requirements, is also facing greater challenges. No doubt, the current backward quarry crusher can not bear the new period of production tasks, we must develop high performance, low energy consumption of new quarry crusher. From the late last century, the computer simulation technology was used to optimize the mechanism, cavity, output and wear. The new type of high performance, low energy consumption, high performance, low energy consumption, high performance and low energy consumption, which greatly improved the performance of the quarry crusher, shortened the product development cycle. However, the research on the optimization design of the quarry crusher is mainly limited to the specific model of the quarry crusher to optimize the design, these procedures are mostly poor reusability, can only solve specific problems in the specific model. However, the optimization of the quarry crusher is based on the requirements of different customers, and so the simulation optimization design work often to repeat a large number of difficult and complex to lock the writing process, and time-consuming, but also to extend the product development cycle. In this paper, we try to use advanced kinematic and dynamic simulation and design tools to develop a new type of quarry crusher, and optimize the design parameters of the mechanism, thus greatly reducing the workload of the simulation design, shorten the product development cycle, improve the simulation model of heavy use rate. In this paper, the kinematics and dynamics simulation of advanced optimization design software ADAMS of the new compound pendulum crushing machine design for simulation and optimization, the main task is optimized crushing machine, a discharging hopper horizontal and vertical travel and travel characteristic coefficient, so as to improve the crushing machine processing capacity, reduce the crushing weight of the machine, enhance the quarry crusher structure strength, reduce the crushing machine lining board wear, thus greatly improve the quarry crusher performance.

Wear low.Design and low cost of the impact of the traditional equipment, the cost of the impact crusher is 30% lower. The finished product is good, and is in the shape of the six sides, and with reasonable distribution, the special use and the mechanism of sand and stone. After a lot of customers use the same power equipment to prove more than the same sand, the overall effect of plastic surgery 30%. From the past experience, all the mineral processing equipment products, including ball mill, sand making machine, magnetic separator, flotation machine, etc. have a certain life cycle. In the life cycle, there will be a market development, expansion of the market, market saturation, shrinking market, and finally gradually fade out the market. According to the Shanghai construction and smelting market analysts said that the life cycle of a particular type of mineral processing equipment is not equal to the situation. For the special equipment of ball mill, its life cycle is very long, some can even reach 10 years. But under normal circumstances, the sand making machine is in its youth stage, there is still a lot of space to develop. So its life cycle is relatively short, generally 2-4 years. So, this requires the majority of sand and gravel equipment manufacturing and production enterprises need to invest in energy for design innovation. Only in the original basis of small function not constant innovation can accumulate over a long period of time, making the entire production line showing a good trend, and eventually accumulated to a qualitative leap. And ultimately the contribution to the entire industry production capacity. Specific to the Shanghai to build their own system of sand production line. Recently, many new products have been gradually coming to market, and get a lot of useful feedback information from. Therefore, the future of the Shanghai construction of a period of time of the sand making machine design concept is to improve the existing product features and technical details.
