Trough idler is used to support conveyor belts and material. Standard trough angle is generally divided into 30°,35°,45°. It includes the standard type and the forward type which can be arranged throughout thewhole course to prevent the conveyor belt from off tracking.
Impact idler is installed under the feeding section. Roller surface is covered with rubber to absorb the impact kinetic energy on the conveyor belt when conveying materials fall down and extend the working life of the conveyor belt.
