The roller is the main part of the belt conveyor, which plays the role of bearing and transmission. The quality of the roller directly affects the service life of the belt. The roller has the advantages of flexible operation, small radial runout, low friction coefficient, good sealing performance, long service life and so on.
In the transfer operation, the conveyor has become an indispensable machinery. But for the conveyor is indispensable to support Kun you know how much? Roller is an important part of belt conveyor, various types, large quantity. It accounts for 35% of the total cost of a belt conveyor, withstand more than 70% of the resistance, the role of the roller is to support the conveyor belt and the weight of the material.
Judging idler or can see roller dust properties, roller waterproofing, roller roller axial bearing capacity, impact resistance, service life of roller radial runout roller; roller flexibility; axial movement etc..
Roller is mainly used in the mining industry, the role of roller is to support the conveyor belt and material weight. Roller operation must be flexible and reliable. To reduce the friction of the conveyor belt and the roller, plays a key role in the life of the conveyor belt, which accounts for more than 25% of the total cost of the conveyor. Although the roller in the belt conveyor is a smaller part of the structure is not complex, but the production of high-quality roller is not easy.
Idler light weight, small inertia rotation. Roller special polymer materials, light weight, the proportion is 1/7 steel, roller made of this material, the weight is about 1/2 of the ordinary roller, rotary inertia, friction between the supporting roller and the belt small.
Roller bearing seat has two kinds of cast iron and steel plate, the wall thickness of 1.5-4MM, can be customized according to user requirements. There are trough type roller, parallel roller, rubber cushion roller, tapered roller, spiral roller, roller, roller, roller, etc.. |
