Roller is an important part of belt conveyor, there are many kinds and large quantities. It accounts for 35% of the total cost of a belt conveyor and bears more than 70% of the resistance, so the quality of the roller is particularly important. Now idler manufacturers attach great importance to this aspect, and have invested a lot of money and equipment in idler production lines and idler production equipment.

The role of the roller is to support the conveyor belt and the weight of the material. Roller operation should be flexible and reliable. Reducing the friction between the conveyor belt and the roller and the roller accessories plays a key role in the life of the conveyor belt, which accounts for more than 25% of the total cost of the conveyor. Although the roller is a small part in the belt conveyor, the structure is not complicated, but the manufacture of high-quality rollers, roller sets is not easy.

1, with the "scrubber" function and longitudinal labyrinth sealing structure of the roller, in the sealing performance simulation and strengthening test bench water test, water does not enter, dust test, spotless, and prevent sludge pollution of the roller.

2, converted service life of more than 100,000 hours;

3. The difference between the bearing positions at both ends of the roller is less than 0.05mm, the radial runout of the outer circle is less than 0.3mm, the rotating resistance is less than 1N, and the mass of the rotating part is reduced by 1/3, which can enable the belt conveyor to achieve long distance, large volume and high speed operation;

4, the roller and the belt basically achieve synchronous operation, wear between each other is small, extended; The service life of the tape and the driving roller;

5, the roller steel pipe is wrapped with tire rubber wear-resistant layer, its anticorrosion, rust and wear resistance are greatly improved, saying goodbye to the traditional roller weight, low precision, high resistance, no wear resistance, easy to damage the age.
