The sieve plate is an important part of the screening machine to complete the screening process. Each sieve shall select a sieve plate that meets the requirements of its work. Properties of materials, different structure of the sieve plate, all sorts of material and sieve machine parameters of vibrating screen screening ability, efficiency, run a sketchy and life have an impact, different materials, different places should choose different sieve plate, screening in order to achieve the best effect. The screen should have sufficient strength, high porosity and non-blocking. When vibrating screen vibrates, the sieve plate can be separated by different shapes and sizes of materials, material size and vibration power, so as to achieve the classification purpose. Comb sieve plate: comb sieve plate has not blocked, significant characteristics of high screening efficiency, applicable to coal, metallurgy, chemical industry of sintering, clinker, coke as well as a variety of raw ore such as high hardness, weight, larger dry material, the sieve plate according to choose material is qualitative different, can achieve different life. According to the different material can be divided into: the new type wear-resisting alloy sieve plate, the high wear-resisting alloy sieve plate, the stainless steel casting sieve plate, the spray sieve plate, the surfacing welding sieve plate, the wear-resisting cast steel sieve plate, the ordinary sieve plate.
