Belt Conveyor Impact Idler And Return Roller With Rubber
the impact idler is used at the receiving place of the belt conveyor to slow down the impact of the blanking on the conveyor belt. It is a type of idler mainly developed for corrosive environments such as coal washing plants, coking plants, and chemical plants. , Its toughness is more than 10 times that of ordinary metals, its life is five times that of traditional column shoes, corrosion resistance, flame retardant, antistatic, light weight and other characteristics, it is widely used in mining. The polymer material specially used for the roller body, its mechanical properties are similar to bronze, it has good wear resistance, and it has good self-lubricating properties, which does not damage the belt. The buffer idler has excellent anti-corrosion performance. The roller body and seals are made of polymer materials, which are corrosion-resistant. Used in corrosive occasions, the service life can reach more than 5 times that of ordinary idlers.
The buffer idler is light in weight and has small rotational inertia. The special polymer material for idlers is light in weight, and its specific gravity is one-seventh of that of steel. The idler made of this material is about one-half of the weight of ordinary idlers, and the rotational inertia is small, and the gap between the idler and the belt is small. friction is small.
use action
1. Before using the idler, carefully check the appearance for serious bump damage. The rotating idler should rotate flexibly without jamming.
2. The installation distance of the idler should be determined by scientific calculation according to the type of logistics and the characteristics of the conveyor, so as to avoid too sparse or too dense installation.
3. The installation of idlers should be adapted to avoid friction with each other.

The role of the idler is to support the weight of the conveyor belt and the material. After the type and model of the tapered idler and friction idler are determined, the combined structure design of the rolling tapered idler and friction idler is required to be accurate. The normal operation of the tapered roller and friction roller. The combined structure design of tapered roller and friction roller includes
The role of the roller is to reduce the friction between the conveyor belt and the roller, which accounts for more than 25% of the total cost of the conveyor and plays a key role in the life of the conveyor belt. Although the roller is a small part in the belt conveyor, the structure is not complicated, but it is not easy to make a good quality roller. The trough roller set is an important part of the belt conveyor, with many types and large quantities. It accounts for 35% of the total cost of a belt conveyor and bears more than 70% of the resistance. Therefore, the quality of the roller is particularly important. The radial runout of the roller affects the belt conveyor. Within the range of runout specified in our country, the belt conveyor can be kept running smoothly, otherwise it will cause the belt conveyor belt to resonate and jump, causing material toss and polluting the environment. The higher the belt speed, the more it appears that the radial runout is small.
1. Lubrication and sealing of tapered rollers and friction rollers
2. Coordination of tapered roller, friction roller and related parts;
3. Shafting support end structure
4. Improve the rigidity of the tapered roller and friction roller system.
