Features: 1. Good wear resistance, long service life, more than 10 times as much as metal screen, 3-5 times of ordinary rubber sheet, 2-3 times as high as stainless steel. 2. The consumption of tons of ore is lower than that of metal sieve plate. 3. Good resistance to wet and abrasion resistance. 4. Absorption and noise reduction, 10 bb more than metal sieve plate (net). 5. Automatic cleaning, since the characteristics of the secondary vibration of polyurethane are not blocked and the screening efficiency is high [1] Material: stainless steel, low carbon steel plate, cold rolled coil
