Carrier Roller

Carrier Roller is an important part of belt conveyor, with many kinds and large quantity. The function is to support the belt, reduce the running resistance of the belt, and make the verticality of the belt not exceed a certain limit to ensure the smooth running of the belt.
According to their uses, the rollers are classified as centering rollers, buffer rollers, grooved rollers and parallel rollers. The function of centering rollers is to correct the runout of belt conveyor, usually rotary slotted centering rollers are installed on the heavy load section of the conveyor, and parallel centering rollers are installed on the no-load section. Buffer rollers are applied to the tailstock according to the actual situation. When receiving material, it can reduce the impact of material on the belt, which is conducive to the service life along the long belt. Slotted roller is generally composed of two side rollers and one flat roller, the slot angle is generally 30 degrees, for the detachable belt conveyor, the three rollers of slotted roller are hinged together with each other, so it is called articulated roller. The parallel roller is generally a long roller, which is installed at the lower end of bearing pressure, so it is called the lower roller.
The rollers are divided into steel and plastic rollers in terms of material. There are three kinds of bearing seats for the rollers, such as cast iron and steel plate stamping and phenolic plastic.
The sealing of the rollers is divided into steel and plastic. Their seals are filled with grease inside. The good or bad of the roller directly affects the power consumption of the belt conveyor and the life of the belt. Therefore, reliable dustproof seal and good lubrication are important criteria for use.
The quality of the rollers is especially important as they account for 35% of the total cost of a belt conveyor and generate more than 70% of the resistance.
