I. Structural characteristics
- Unique shape: Composed of multiple idlers arranged at a certain angle to form a trough structure. Usually, the middle idler is horizontal, and the idlers on both sides are inclined at a certain angle, resembling the shape of a "V".
- Sturdy and durable: Made of high-quality steel or other wear-resistant materials, it has strong bearing capacity and impact resistance and can adapt to harsh working environments.
II. Performance characteristics
- Good guiding property: The trough structure can play a good guiding role for the conveyor belt, prevent the conveyor belt from deviating, and ensure the stable transportation of materials.
- Increase the conveying inclination angle: Compared with parallel idlers, the trough idler set can increase the conveying inclination angle of the conveyor belt to a certain extent, improve space utilization, and is suitable for occasions with complex terrain.
- Strong bearing capacity: Since the trough structure can better wrap the conveyor belt and materials, the bearing capacity of the idler set is greatly improved, which can meet the needs of heavy-load transportation.
- Low friction coefficient: The friction coefficient between the idler and the conveyor belt is small, reducing running resistance, reducing power consumption, and improving conveying efficiency.
III. Characteristics of application scope
- Widely used: Applicable to the transportation of various bulk materials, such as coal, ore, grain, etc. Especially widely used in belt conveyors in industries such as mines, ports, and power.
- Adapt to different belt widths: Can be customized according to different conveyor belt widths to meet the needs of different conveying systems.
IV. Maintenance characteristics
- Convenient maintenance: The structure is relatively simple and easy to inspect and maintain. When the idler fails, it can be quickly replaced to reduce downtime.
- Longer service life: Adopting high-quality bearings and seals reduces wear inside the idler and the entry of impurities, prolonging the service life of the idler set.
- Roller/idler introduction:
Rollers/idlers are important components of belt conveyors. Their function is to effectively support the conveyor belt and the materials carried on the conveyor belt, ensuring the normal operation of the conveyor. The diameters of idlers have domestic standards and foreign standards.
Domestic standards:Φ63,Φ76,Φ89,Φ108,Φ133,Φ159,Φ194,Φ219;
Foreign standards: Φ 89,Φ102,Φ114,Φ 127,Φ 139,Φ152,Φ 165,Φ 178 and other specifications.
