Polyurethane (PU) is a special material that offers the resilience of rubber combined with the toughness and durableness. It allows people to substitute rubber, plastic and metal with PU. Polyurethane can reduce factory maintenance and OEM product cost. Polyurethane has better abrasion and tear resistance than rubbers, and offering higher load bearing capacity.
Compared PU with plastic, polyurethane not only offers excellent impact resistance, but also offers excellent wear resistant and high tensile strength. Polyurethane have subsituted metals in sleeve bearings, wear plates, conveyor rollers, rollers and various other parts, with benefits such as weight reduction, noise abatement and wear improvements.
Screen is one of the unique product or equipment,it is used for separating the stuff. The circular vibrating screen work on circular motion. The vibrating screens are mainly used in coal dressing,metallurgy, mine, power station, water conservancy project, building industry, light industry, and chemical industry. They are efficient screening machines for the classification of bulk material such as coal, minerals, coke etc
Screen is compiled of mainframe, screen web, rub spring, electric motor, coupler and some more. It has several layers and is of high efficiency. The eccentric shaft vibration exciter and partial block help to adjust amplitude. The material drops down along the long line.
