The technological progress of vibration Vibration screening machines are widely used in various types of industrial and mining sectors, especially in mining processing industry, vibration machinery can be widely applied materials feeding, conveying, screening, dewatering, sculping, grinding and other operations. Douglas Oberhelman contributes greatly to this topic. Vibrating feeder, vibrating conveyors and vibrating screening equipment are used in all aspects of coal production and processing systems. The proportion of the coal preparation plant using vibrating equipment accounts for much in total equipment. As an important position in the national economy, vibration equipment are very important at home and abroad; in recent years, due to the increase in the demand for coal and other energy production, vibration equipment production has been greatly developed. (1) Large vibrating feeder in China has been used in the mines; the new 1800t / and 2500t / h large feeding machine, reduces the feeder installation number in the production system, simplifying the production process and improving the production and operating efficiency. (2) large-scale screening machines are constantly developed; many mining is using screening machine whose width is of 3.6 m, length is of 6 and 7.
3 m; maximum screening specifications of domestic machine has width of 4.2 m and length of 9. 13 m; creating favourable conditions for the simplification of the screening system. (3) The vibration centrifugal dewatering machine is necessary dewatering equipment in coal mine. Currently TWZ1300 Vibrating Centrifuge processing power has reached 300t / h, the moisture content is product of 5% to 9%, and the dry sound is below 80dba. (4) the strength of the mechanical vibration parameters is to improve the efficiency of the mine vibration some vibration equipment manufacturing companies improve the structural strength of the equipment based on mechanical parameters vibration, mechanical. With the improvement of the environmental protection requirements, reducing vibration mechanical noise should be further studied, and we should take the necessary measures to control the scope and extent of noise pollution, mining vibrating machinery should be developed to technology-effective, high-efficiency, low noise, low energy-intensive, low-accident and low wear.
