What are the basic types of rollers that are coated with rollers? Today, there are technicians from ZHENGTAN METALLUGY manufacturers to explain to customers and friends.
1. The rollers are classified into self-aligning rollers, buffer rollers, groove rollers and parallel rollers according to their uses. The function of the self-aligning roller is to correct the deviation of the belt conveyor. Usually, the rotary trough-shaped idler roller is installed on the heavy-duty section of the conveyor, and the parallel self-aligning roller is installed on the empty section. The buffer roller is applied to the tailstock according to the actual situation. When receiving the material, the impact of the material on the belt can be reduced, which is beneficial to the service life of the long belt.
2. The trough-shaped idler generally consists of two side rollers and a flat roller. The groove angle is generally 30 degrees. For the detachable belt conveyor, the three rollers of the grooved roller are hinged to each other. , so called the articulated roller. The parallel roller is generally a long roller which is mounted at the lower end of the pressure and is called the lower roller.
3. The roller is divided into steel and plastic roller in the material. The bearing housings of the rollers are cast iron and steel stamped and phenolic plastic. The seal of the roller is divided into steel and plastic. Their seals are internally filled with grease. The quality of the roller directly affects the power consumption of the belt conveyor and the life of the belt. Therefore, the dustproof seal is reliable, and good lubrication is an important standard of use. The roller accounts for 35% of the total cost of a belt conveyor and withstands more than 70% of the resistance, so the quality of the roller is particularly important.
