Polyurethane screens are mining equipment used in mines and quarries. With the rapid development of the national economy, the demand for copper, iron and other metals has increased rapidly, and the demand for coke, which is a reducing agent for copper and iron, is still very large.
For a long time, the upgrade of several generations of screening components in coke screening projects has finally been locked in polyurethane screening. Its characteristics of long service life, high productivity and high screening rate are deeply loved and paid attention to by coke screening enterprises.
Polyurethane screens have long service life and large load-bearing capacity. Because the polyurethane elastic screen plate uses steel wire rope as the skeleton material, polyurethane itself has high elastic modulus, high strength, impact resistance and high wear resistance, so it has high tensile strength, and its load-bearing capacity is more than 2.5 times that of the rubber screen plate.
Polyurethane screen has high screening efficiency. The screen surface has self-cleaning performance, no clogging, and high screening efficiency. High screening efficiency. The production process of the polyurethane screen plate adopts the molding process, with accurate aperture and high screening quality. The particle size of the screened material can well meet the user’s requirements.
Low operating noise of polyurethane screen. Actual measurement results show that the same screening machine using polyurethane screen plates can reduce noise by 5-20 decibels compared with metal screen plates. Has significant economic benefits. The price of polyurethane rubber surface is higher than that of metal screen plates, but considering factors such as screening rate, maintenance cost and service life, the comprehensive benefits of polyurethane screen plates are significantly better than ordinary metal screen plates.
