The conveyor idler is an important part of the belt conveyor. It has many types and large quantities. It accounts for 35% of the total cost of the belt conveyor and generates more than 70% resistance. Therefore, the quality of the conveyor idler is particularly important.
The function of the conveyor idler is to support the weight of the conveyor belt and the material. The operation of the conveyor idlers must be flexible and reliable. Reducing the friction between the conveyor belt and the supporting conveyor idlers plays a key role in the service life of the conveyor belt, which accounts for more than 25% of the total cost of the conveyor belt. The conveyor idler is a small part of the belt conveyor. Its structure is not complicated, but it is not easy to produce high-quality conveyor idlers.
The criteria for judging the quality of the conveyor idler are as follows: the radial runout of the conveyor idler; the flexibility of the conveyor idler; and the axial shift.
Basic type of conveyor idler
Idle conveyor idler is an important part of the belt conveyor, with many types and large quantities. The function is to support the belt, reduce the running resistance of the belt, and make the verticality of the belt not exceed a certain limit to ensure that the belt runs smoothly.
Conveyor idler can be divided into self-aligning conveyor idler, impact conveyor idler, troughing conveyor idler and parallel conveyor idler. The function of the self-aligning conveyor idler is to correct the deviation of the belt conveyor. Normally, the rotary trough centering conveyor idler is installed in the heavy load section of the conveyor, and the parallel centering conveyor idler is installed in the no-load section. The tailstock adopts impact conveyor idlers according to the actual situation. When receiving the material, the impact of the material on the belt can be reduced, which is beneficial to the service life of the belt along the long belt. Slotted conveyor idler is generally composed of two sides conveyor idler and flat conveyor idler. The trough angle is generally 30 degrees. For movable belt conveyors, the three-conveyor idler of the trough idler are hinged to each other, which is called an articulated idler. The parallel conveyor idler is generally a long conveyor idler installed at the lower pressure end, so it is called the lower conveyor idler.
Conveyor idler are divided into two types: steel and plastic. There are three types of idler bearing housings: cast iron, steel stamping, and phenolic plastic.
The seal of the conveyor idler is divided into steel and plastic. They are sealed with grease inside. The quality of the conveyor idler directly affects the power consumption of the belt conveyor and the life of the belt. Therefore, the dustproof seal is reliable and the lubrication is important.
Conveyor idlers account for 35% of the total cost of the belt conveyor, and the resistance is greater than 70%, so the quality of the conveyor idlers is particularly important.
