Answer: According to different structures, the material of the sieve plate and the various parameters of the sieve machine have certain influence on the screening ability, efficiency, running rate and life of the vibrating screen. Different materials and different places should use different sieve plates to achieve the excellent effect of screening. When selecting the sieve plate, most people will choose high-manganese steel material, which is relatively wear-resistant and has certain toughness. Because each manufacturer's technology is different, their production quality will be different. The sieve plate belongs to the casting part. Under normal circumstances, the equipment must be customized. As long as you know the thickness of the sieve plate, the size of the hole, the curvature, the length and other data, you can make a sieve plate suitable for your equipment.
