Return Roller with Space Rings
Rollers with spaced rings are used to sustain and support the belt during its return section, where the conveyed material tends to stick to the belt or wherever there is a wear problem or tracking problem of the belt itself. The rubber rings may function in the temperature range between -20°C + 80°C. When a return roller with spaced rings is not sufficient to resolve the problem, it is recommended to mount self-cleaning rollers, with rings in helical rubber form or with a spiral metal cage, taking into account in the roller positioning that the dislodged material should travel outwards to the belt edge and not towards its center.
Rubber disc idlers are belt-friendly and positioned at the return side of the belt. A rubber disc return idler is frequently used to remove carryback from the belt.
