1. The impact roller is driven by a motor through a reducer, and the conveyor belt is dragged by the friction between the drive pulley and the conveyor belt. Reliable anti-skid measures must be taken for the ramp on the scaffold and the transportation road in the field, except that it should be cleaned in time. In addition to frost and snow, methods such as dusting furnace ash, sawdust, and sand can also be used to prevent slippage.

      2.  All technical requirements must be in accordance with the manual trough-shaped roller. The role of the roller is to support the weight of the conveyor belt and the material, reduce the friction between the conveyor belt and the roller, and affect the life of the conveyor belt that accounts for more than 25% of the total cost of the conveyor.

      3. There are five other criteria for judging the quality of rollers:

      1. Dustproof performance of roller

      2. Waterproof performance of roller

      3. The axial bearing performance of the roller

      4. The impact resistance of the roller

      5. The service life of the roller. The roller is an important part of the belt conveyor. There are many types and large quantities.

      The heat-resistant conveyor belt is mainly based on the main performance of the heat-resistant belt’s damage and loss of conveying capacity and different heat-resistant levels. The reform of the conveyor belt has become the focus of environmental protection. It is no wonder that it is such a common one to protect the environment and save raw materials. Simple products, countless relevant professional scientific research institutes and engineering technicians engaged in production at home and abroad are committed to the research and improvement of rollers. There are hundreds of patents declared, and none of them can solve the problem of roller fragility.

      The structure chain plate feeder is composed of silo interface, material guide groove, manual gate device, drive sprocket set, supporting wheel set, underframe and other parts. The components are connected by bolts, transported and assembled, and can be separated and integrated. Trough-shaped rollers are suitable for ground or underground mines. The main reasons for damage to roller bearings in coal mines are as follows: Sprinkling water and slime contaminate the roller bearings, causing the bearing resistance to increase until it jams and fails; Self-aligning brackets are installed The frictional self-aligning roller is not perpendicular to the tape at 90 degrees, but uses lateral friction to force the tape to prevent deviation. The tube wall of the roller will wear quickly, and the tape will wear very seriously. This shows that the conveyor belt support Rollers play a key role in the life of the conveyor.
