108mm Self Aligning Return Idler DTII A Conveyor Belt Return Rollers
Wear Resisting Iron Disc Return Roller For Mining , Port , Power Plant Industries
Self Aligning Return Idler is usually used for the transportation of acid and alkali resistant industry. The comb type idler can replace
metal rollers and nylon rollers with longer service life and simple installation, can reduce the deviation of conveyor belt,
protect the belt from wearing, which has a superior performance than traditional rollers.
Conveyors Rubber Disc Return Idlers operate by utilising durable rubber discs positioned at regular intervals along the roller to effectively eliminate conveyor belt carry back build up.This is done by breaking up the material on the return side of the conveyor belt which is normally concentrated in the centre of the belt.Rubber Disc Return Roller JoyrollThe rubber discs avoid the build up of material that can be deposited onto the roller surface which can cause the roller diameter to develop an irregular worn surface and change shape.This is often a major cause of belt mistracking. rubber disc roller are a reliable and simple maintenance solution to this common belt conveyor problem.Rollers,Idler Frames Structure Rollers Idler Frames Structure Quality Rollers built-to-last Steel rollers - three feature levels available.
Working principle of comb type roller:
The roller drives the roller tube, the bearing seat, the outer ring of the bearing, and the seal ring to rotate through the friction between the conveyor belt and the roller, and realizes the transmission of logistics together with the conveyor belt.
Operation:
1. Before using the roller, carefully check the appearance for any serious bumps and damage. The rotating roller should rotate flexibly without jamming.
2. The installation distance of the rollers should be determined by scientific calculations based on the type of logistics and the characteristics of the conveyor, and avoid excessive or dense installation.
3. The roller installation should be adapted to avoid friction between each other.
