Types of conveyor rollers

      Conveyor roller is the important part for belt conveyor.It covers many types,and accounts for 35% of the total cost of a belt conveyor. The roller is to support the weight of both conveyor belt and material.

       According to material and application, conveyor roller can be divided into different types.

       According to the material made of, the roller can be divided into metal roller, ceramic roller, rubber roller and plastic (nylon) roller.
         ● Metal roller: The roller with good impact resistant is not easy to deformation, but it can not be impacted repeatedly, or it will be easy to fracture. Also the roller is easy to rust and wear, it will tear the belt in case any wear.
         ● Ceramic roller: The roller is insulation, wear-resisting, corrosion resistant, non-stick, but it is easy to fracture as the low impact resistant.
         ● Rubber roller: The roll is very light and with good performance in shock absorption, but it is with high friction coefficient, poor seal performance, easy aging and easy to drop black particles to affect the quality of conveying materials.
         ● Plastic(Nylon) roller: The roller is dust-proof, waterproof, corrosion-resistant, smaller power consumption, lower noise, and with long service life. The suitable temperature is less than 80℃.

      According to application, roller can be divided into trough roller, flat carrying roller, self aligning roller, impact roller, return roller, finger type roller and spiral roller.
        ● Trough roller: The roller is used to carry bulk materials.
        ● Flat carrying roller: The roller is used to carry finished packed goods.
        ● Self aligning roller: The roller is used to adjust the belt deviation, to prevent hunting, and to ensure the smooth operation of conveyor belt.
        ● Impact roller: It is installed under of the conveyor section of material arrival to reduce the impact of the conveyor belt.
        ● Return roller: It is  used for the belt return back. There are parallel and V shaped roller.
        ● Finger type roller and spiral roller: These two types rollers are used to clean the belt stuck with materials.
