Belt Conveyor Spiral Idler

The spiral roller is mainly used to clean the debris adhered to the tape and can adjust the deviation. The structural form is that ordinary rollers are welded with left and right spiral round steel with a diameter of 10 to 14 mm or a spiral groove cast rubber sleeve is added to the outer surface to increase the wear resistance of the entire roller and to clean the adhesive on the tape. It effectively ensures the service life of the belt conveyor belt, and also plays the role of centering and preventing deviation.

The principle of spiral rollers to prevent deviation is: the two side rollers in the roller group are both spiral rollers with tapers, but the threads are in different directions. The roller on one side is left-handed and the roller on the other side is right-handed. Rotate so that the lateral forces given to the conveyor belt are directed toward the centerline. When the conveyor belt is running, axial forces are generated due to the action of the spiral. When the conveyor belt deviates, it slides to one side and is pushed toward the belt by the helix angle. The force is greater toward the outside. At this time, the two rollers exert different forces to push the conveyor belt. The difference between these two forces will cause the conveyor belt to deviate. With reset. When the spiral roller is installed on the conveyor belt, the spiral of the middle roller should be bidirectional, that is, one end is a left spiral and the other end is a right spiral. The rollers on both sides have left-hand threads on one side and right-hand threads on the other side. The key to installing spiral rollers is to face the tail of the conveyor, then install a right-hand threaded roller on the right hand side and a left-hand threaded roller on the left hand side.

Belt Conveyor Idlers Industry knowledge

The process of Spiral Idler cleaning debris adhering to the conveyor belt relies on its unique structural design and physical mechanism

Spiral design principle: The outer surface of the spiral roller is equipped with left-handed and right-handed spiral steel bars or spiral groove rubber sleeves. This design generates an inward or outward thrust through the rotation of the spiral, which helps to clean the debris attached to the surface while the conveyor belt is running.

Friction and extrusion: When the conveyor belt passes through the spiral roller, friction is generated between the rotation of the roller and the conveyor belt. This friction not only loosens the adhered debris, but also uses the geometric shape of the spiral structure to gradually squeeze the debris to the outside of the roller, causing them to detach from the conveyor belt.

Self-cleaning mechanism: The design of the spiral roller makes it so that once there is debris attached to the roller, the rotating spiral pushes these debris outward, forming a self-cleaning effect. This self-cleaning ability is particularly suitable for the transportation of wet and sticky materials, reducing the wear of the conveyor belt caused by the attachment of materials.

Transverse force adjustment: The rollers on both sides of the spiral roller have spiral designs in different directions, which can apply different lateral forces. This design allows the spiral roller to apply a vector force to the conveyor belt when it deviates from the center, pushing it back to the center, thereby reducing the accumulation of materials.

Reduced risk of blockage: When handling wet or sticky materials, the self-cleaning mechanism of the spiral roller can effectively prevent the accumulation and blockage of materials, ensuring the smooth operation of the conveyor belt. This is particularly important under high load or long-term operation conditions.

Reduced maintenance costs: Since the spiral roller can efficiently clean the conveyor belt, the accumulation of debris is reduced, thereby reducing the wear on the conveyor belt. This feature reduces the maintenance frequency of the equipment and effectively controls the operating costs.

Wide range of applicable industries: The design of the spiral roller is particularly suitable for industries such as steel, chemicals, and mining. It can efficiently handle wet and sticky materials and improve the efficiency and reliability of the conveying system.

Energy efficiency optimization: The efficient self-cleaning function of the spiral roller not only improves the operating efficiency of the conveyor belt, but also reduces energy consumption to a certain extent, because it reduces the additional energy loss caused by friction and blockage.

Operation stability: While preventing the conveyor belt from deflecting, the spiral roller ensures the stable transmission of materials, reduces mechanical failures caused by deviation, and improves the overall stability of the system.

Environmental adaptability: The spiral roller can work in a variety of environments, including high humidity, high viscosity and dusty environments, which enables it to perform well in cleaning and conveying performance in different industrial occasions.
