The idler roller of a belt conveyor is the most important component of a belt conveyor, and it is also the component that occupies the largest number of belt conveyors. The idler roller of a belt conveyor is different from the unpowered drum used for material conveying, although its composition and appearance are similar. However, the carrying capacity of the belt conveyor rollers is relatively large, and there are corresponding limitations on the speed. Belt conveyor roller.
The standard groove angle for the groove type idler is 35 degrees, so the most commonly used in each conveyor are the 35 degree groove type idler and the 35 degree groove type forward leaning idler.
Buffer rollers have 35 degree and 45 degree options. When using canvas conveyor belts, only 35 degree groove type buffer rollers can be selected. When using a 45 degree groove type buffer roller, it can be used in the section of the guide groove that is not affected by material impact.
Large capacity, long-distance, high belt tension, and important conveyors should generally be equipped with transition sections.
The return roller, also known as the parallel lower roller, is the most commonly used type of lower roller.
Self aligning rollers include ordinary self-aligning rollers, friction self-aligning rollers, and conical self-aligning rollers. The self-aligning roller is used to automatically correct excessive deviation of the conveyor belt during operation, ensuring the normal operation of the conveyor.
The idler roller is the most critical component of a belt conveyor. It supports the conveyor belt and the material being transported, reduces belt sagging, and ensures smooth and efficient operation of the conveyor system.
The standard groove angle for a groove type idler is 35 degrees. The 35-degree groove type idler and 35-degree groove type forward leaning idler are the most commonly used configurations in belt conveyor systems.
A 45-degree groove type buffer roller can be used in sections of the guide groove that are not directly affected by material impact. For canvas conveyor belts, however, only the 35-degree groove type buffer roller should be selected.
The return idler (parallel lower roller) supports the underside of the belt on its return path. The transition roller is used at the feed and discharge ends of the conveyor to provide a smooth change in belt shape, and is recommended for high-capacity, long-distance, or high belt tension applications.
Self-aligning rollers automatically detect and correct excessive lateral deviation of the conveyor belt during operation. They come in three types — ordinary, friction, and conical — each designed to restore proper belt alignment and ensure the conveyor runs normally.
Although a belt conveyor idler roller and an unpowered drum look similar in composition and appearance, the idler roller is engineered specifically for belt conveyors with higher carrying capacity requirements and defined speed limitations, making it more robust and precise than a standard unpowered drum.
