ibrating screen is of multilayer and high efficiency( three layers or four layers), it is often used in the behind of Jaw Crusher or Impact Crusher. Hongxing Vibrating screen adopted eccentric shaft vibration exciter and partial block helps to adjust amplitude, this kind of screen is of long stream line,many specifications and clear screening for different specifications. So it is widely used in the industries of quarry, building material,traffic,energy,chemistry,etc. The circular vibrating screen plays a big role of screening various materials in metallurgy, mine, chemicaletc industries. Nowadays along with further economic development in China, there are higher requirements for the production capacity of many production machineries For example; the quick building of highway construction and the big market demand of nonferrous metal bring a good opportunity to the development of circular vibrating screen. So what factors restrict the development of current vibration screen in China? For example, China's steel production is largely relied on importing of iron ore. But in recent years the iron ore import prices rose too much, which results in the increasing cost of iron ore. If we wanted to reduce the dependence on importing of iron ore, we should put our hands to our local iron ore. But we must adopt better screening and cleaning equipment to process in order to make our low quality iron ore satisfy the requirement of iron and steel industry. Then a good vibration sieve is necessary.

So it is visible that the demand of circular vibrating screens is under the growing market demandat present. Although there are big market demands for circular vibrating screen in China,there is lack of advanced screening equipmentand there also are many problems in the development of circular vibrating screen. Thisis the factor ofrestricting the development of our vibration screen obviously. Then what is the further direction of development for high efficiency vibrating screen in China? Let’s discuss from below several parts. For example, firstly we need to improve its screening efficiency and screening quality and reinforce the strength of screening. Secondly, we should build various light-weights, convenient and highly efficient screening machineries of suiting for industrial manufacture and human’s life from environmental protection,energy conservation and serialization
