89x240mm Carrying Mining Belt Conveyor Idler Rollers Heat Resistant

Product Specification

89X240mm Steel Carrying Belt Conveyor Idler Rollers Mining Belt Conveyor Roller

1. Strong hardness and high wear resistance;

2. Good Sealing Performance - the carrying roller is fully sealed, and both ends are equipped with labyrinth seals, oil and grease will not leak, which can make the roller runs under a fully sealing state;

3. Long Service Life - the carrying roller can reduce belt wear, keep the belt run in its track, and extends the belt life;

4. Low Operating Cost - carrying rollers can reduce the overall cost of belt conveyors and reduce maintenance man-hours.

Utilization and operation of rollers:

1. Before using the roller, check the appearance carefully for any serious bumps and damage. The rotating roller should be sensitive and free from jamming.
2. The installation distance of the rollers should be determined by scientific calculations based on the type of logistics and the characteristic transportation volume of the conveyor, so as to avoid excessive or dense installation.
3. The roller installation should be used to avoid rubbing against each other.

Characteristics for Transport Roller

1. Flat/Carrier/Carrying Rollers: Used to handle bulk&unit material.
2. Impact Rollers: Installed at the loading point to absorb the shocks and to help protect against belt damage.
3. Return Rollers: Used to sustain and support the belt during its return section and performs a cleaning action
--- Return rollers with Spaced Rings (Rubber Disc Rollers)
--- Return Rollers with Helical Rubber Rings (Spiral Rollers)
4. Self-aligning/Training Rollers: Used to adjust the belt deviation, preventing hunting and ensuring stable operation of conveyor belt.
--- Tapered self-aligning rollers
--- Friction self-aligning rollers

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. 

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

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.
