Technical development of vibrating screen

Vibrating screening machinery is widely used in mining, metallurgy, coal, water conservancy and electric power, petrochemical industry, railroad transportation, grain processing, medicine and environmental protection and other industrial sectors, to complete the screening, classification, washing, dewatering, desorption and other different processes.

With the urgent need for modern science and technology and modern construction, vibrating screening machinery not only in the variety, but also in the quality of products have put forward higher and higher requirements, in this situation, the research of vibrating screening equipment has been developed rapidly, and has made great contributions to China's economic construction.

Foreign research and production of vibratory screening machinery has been carried out since the sixteenth century. In the 18th century in Europe during the industrial revolution, vibrating screening machinery has been rapidly developed, to the 20th century, the development of vibrating screening machinery has reached a high level. At present the oldest known vibrating screening machinery should be fixed sieve, use, will be sieved material poured on the fixed sieve plate, the large pieces of material left on the screen surface pick out by hand, and then hammer to pick out the large pieces of material broken, so that it reaches the required particle size level, so it is said that the fixed sieve is the oldest sieve in all vibrating screening equipment. At the same time, some fixed sieve screen surface by plus a number of parallel arrangement of shaped cross-section of the helper bar, which is today's bar screen. Many industries continue to put forward various requirements for vibrating screening machinery, promoting the development of vibrating screening machinery and process progress, such as cylindrical sieve, swing sieve and vibrating sieve and other kinds of vibrating screening machinery and equipment, are introduced successively to meet the needs of various industries.
