Compared with metal liners, rubber and polyurethane liners has the following features:

Light in weight, easy for assembling and disassembling，reduce worker labor;

High damping capacity resulting in reduced noise. Good elasticity, increase the beat frequency of the material, improve screening capacity;

Less blockage. Due to the abrasiveness of the rubber, keep the stable size of the apertures can assure the Screening accuracy above 90%.
