Our factory can do it all for bulk material companies, making it simple for everyone to design and order custom rollers and affordable matching roller frames online.
The Equal Trough impact idler, a conventional type carrier roller set, consists of three equal-length impact idlers supporting three rollers in one frame that is fixed to the conveyor structure. In quarry and mining applications, when large, heavy and sharp materials fall on the conveyor, they can impact and damage the belt, ultimately leading to downtime and higher replacement costs. Therefore, an impact idler is needed in the material impact area.
It is designed with a rubber ring to provide cushioning and absorb impact in the material impact area, minimizing damage to the belt.
The common diameter of the roller tube is （mm)D89/102/108/133/152/159 or as per the order
Belt widths are available in （mm）500/650/800/1000/1200/1400/1600/1800 or customized

The impact idler sets are typically spaced 350 mm to 450 mm apart to provide overall support. It is installed in the first roller group at the conveyor's drop gate.

Applications
Conveyor impact rollers are used for belt conveyors to receive materials and reduce and slow down the impact of the conveyor belt, mainly designed for corrosive environments such as coal washing plants, coking plants, and chemical plants. The impact rollers have good corrosion resistance and if used in corrosive situations, their service life is five times that of ordinary rollers.

How Troughing Idlers Work

Troughing idlers consist of three or more idlers that guide the conveyor belt. They are found on the carrying side of the belt and are installed along the entire length of the conveyor. The troughing idlers work to keep the belt in the same configuration all along its length, which thus maintains the same cross-sectional area as the belt carries mined materials from their source to the drop off point. A troughing idler is comprised of a central idler roll, which has a fixed width, and two or more wing idlers located on each side of the central idler roll. The wing idlers can be adjusted up or down to change the toughing angle, which affects the depth of the trough created by the conveyor belt as it moves.

Benefits of Troughing Idlers

Troughing idlers offer two important benefits. First, the troughing idlers keep the belt’s shape consistent throughout its journey, which improves both stability and carrying capacity. Second, troughing idlers reduce the amount of material that may accidentally spill over the edge of the conveyor system, which improves productivity and also increases the safety of workers, who may be at risk from falling material while working near conveying equipment.
