1.Good screening effect.
PU screen is made of PU, which has good elasticity. PU has strong water permeability and large mesh cone angle, which can effectively prevent the adhesion of wet fine particles. Therefore, it is suitable for screening and grading of moist fine-grained materials, and the screen is easy to clean and easy to operate.
PU screens are professionally used in hydropower stations, building materials and other metal beneficiation industries. Screening various materials in the range of 0.1mm-170mm, whether dry or wet, will not affect the screening efficiency.
- Save energy and protect the environment. Due to the light weight and small dynamic load of the PU screen, compared with the metal screen, the noise can be reduced by 5-20 decibels, and the dust flying is also greatly reduced, which reduces the pollution to the screening environment and meets the national environmental protection requirements.
- Long service life. PU elastic screen uses steel wire rope as skeleton material. PU itself has high elasticity, high impact absorption strength and strong wear resistance, so it has high tensile strength, and its bearing capacity is the same as that of rubber screen 2.5 times more than the board. Its service life is 8-10 times that of ordinary metal sieve plates, 3 times that of stainless steel sieve surfaces, and 3.9 times that of natural rubber. It is the screen surface material with the best abrasion resistance in the world.
Although the price of PU rubber screen surface is higher than that of metal screen plate, its screening effect and service life are unmatched by ordinary metal screen surface. Therefore, the choice of PU screen surface for mine vibrating screen is an inevitable choice.
