Screening equipment is screening machinery that is widely used in industrial and mining enterprises, it can be used to screen and grade a universal materials. The pros and cons of the level and quality of screening equipment technology is closely related to the processing effect and the level of production efficiency and the level of energy savings, which directly affect the economic efficiency of enterprises. Circular vibrating screen has an absolute advantage in all screening equipment by its simple structure, large capacity, reliable work, etc., it occupies about 95%.
The development of screening equipment
Foreign countries from the 16th century began to research and produce screening equipment, in the 18th century during the industrial revolution in Europe, screening equipment has been developing rapidly, the century of vibration screening equipment has been developed to a higher level. Foreign countries have many manufacturers of vibrating screens, the United States has AC., R • S companies, the RNO developed DF11 double frequency sieve, using a different speed of the exciter. The DRK the company developed into a three-way splitter feed vibrating screen, a high-speed motor drive. West Germany KHD company produces over 200 kinds of specifications screening equipment, the high degree of common sieve companies, Schenck can provides more than 260 kinds of screening equipment, Japan's Kobe Steel, Ltd., Kawasaki Heavy Industries Ltd., Furukawa Mining Co., Ltd.,Tokai Co., Ltd. and RXR cooperate with each other and develop the vertical material flow sieve, which combine the rotary motion and cycle motion, which is particularly effective to the a grading gor fine materials. In order to sieve fine grained coal from the wet raw coal, Uk successful develops the cyclone probability screen.
