Buffer roller for belt conveyor by cutting slow blanking impact on the conveyor, mainly for coal preparation plant, coking plant, chemical plants and other corrosive environment and the development of a class of roller and its toughness is more than 10 times the ordinary metal, life is five times as large as that of the traditional column shoe, corrosion resistance and flame retardant, antistatic, and light in weight, characteristics, widely used in mining. High polymer material, which is similar to that of bronze, has good mechanical properties, has good wear resistance, and has good self - lubricating property, without injury to the belt. Buffer roller anticorrosion performance. Roller body and sealing parts are made of polymer materials, corrosion resistance. Use in corrosive occasions, the use of life can reach more than 5 times the ordinary roller.
Buffer roller weight is light, the rotation inertia is small. Light care and special polymer material weight, the proportion is one seventh of the steel, roller made of this material, the weight is about ordinary roller one second, rotary inertia small, supporting small friction between the roller and the belt.
