The taper idler is an important part of the belt conveyor, with a large quantity and a wide variety of types. Taper idler account for 35% of the total cost of a belt conveyor. The taper idler bears more than 70% of the resistance on the belt conveyor, so the quality of the taper roller is very important. The function of the taper idler is to support the weight of the conveyor belt and the material on the belt conveyor. Taper rollers run flexibly. Reduce the friction between the belt conveyor and the taper roller, which plays a key role in the life of the conveyor belt, which accounts for more than 25% of the total cost of the belt conveyor. Working principle ● The rollers on both sides of the double-cone automatic correction device are designed with conical + coated structure. The diameters of both ends of the rollers are different. When the rollers rotate, the linear speeds at the contact point between the size head of the rollers and the be…
