Wear-Resistance HDPE UHMWPE Plastic Roller For Coal Mining Ports Steel Power Cement Coking Alkali Fertilizer Plants
UHMWPE Roller (Ultra High Molecular Weight Polyethylene Roller)
Ultra-high molecular weight polyethylene roller is a new type of roller that is independently developed by our company. It is a core material with high quality material and unique sealing technology. It effectively prevents water and dust from entering the inside of the roller, then it is good protection for bearing. The roller is made from ultra-high molecular weight polyethylene pipe, it has the advantages of light weight, wear resistance, non-stick material, corrosion resistance, etc., and the friction coefficient with the belt is extremely low, and has high self-lubricating performance, which can effectively reduce the belt of transportation Energy Consumption. It can avoid the tearing of the belt when the metal roller is broken, and the belt of using life can be extended by more than 20%, which helps the enterprise to save costs.
The characteristic of UHMWPE Roller
Light weight:The ultra-high molecular weight polyethylene roller is only one-third of the weight of the metal roller of the same specification. It is easy to install, easy to change, low moment of inertia, stable operation, low driving energy consumption and low noise, which can effectively reduce the belt beating, running away, overflowing, and dropping during conveying process.
Wear-resistance:Ultra-high molecular weight polyethylene is one of the most wear-resistant engineering materials, thus greatly improving the service life of the roller in an easy-wear environment.
Self-lubrication:The surface is not easy to adhere to materials or scale, and the friction coefficient is very low, which greatly reduces the friction between the roller and the rubber belt, once the roller cannot be turned, "bite" the belt accident will not happen.
Bearing with sealing cover is adopted, and labyrinth groove and circlip are used to seal the roller, bearing seat and steel shaft, so that the waterproof, acid-alkali and dustproof effect is more significant. UHMWPE roller, as the replacement product of metal roller, is widely used in places with large dust, strong corrosion and extremely harsh conditions, such as mines, coal mines, ports, power plants, steel plants, cement plants, coking plants, alkali plants and fertilizer plants.
