Buffer rollers are used in belt conveyor material to mitigate the impact of falling material on conveyor belts, mainly for coal washing plants, coking plants, chemical plants and other corrosive environment and developed a class of rollers, it has its own toughness is more than 10 times that of ordinary metals, life is five times that of traditional column shoes, corrosion-resistant flame retardant, anti-static, self-weight and so on, widely used in mining. The polymer material dedicated to the roller body, whose mechanical properties are similar to bronze, has good wear resistance, and has good self-lubricating properties, does not hurt the belt. The anti-corrosion performance of the buffer roller is superior. Rollers and seals are made of polymeric materials and are resistant to corrosion. In corrosive applications, the service life can reach more than 5 times that of ordinary rollers.

<p>The roller is an important part of the belt conveyor. There are 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, so the quality of the roller is particularly important. Now the support Roller manufacturers attach great importance to this aspect, and have invested a lot of money and equipment in the roller production line and roller production equipment. The role of the roller is to support the weight of the conveyor belt and the material. The roller must be flexible and reliable in operation. Reduce transportation The friction with the same roller and 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 it is not easy to manufacture high-quality rollers and roller sets.</p>
