Suspended Rollers for Trough-shaped Belt Conveyors - China Factory Suppliers of Durable Idlers
Overview
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
Types of Rollers
Groove Type Upper 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 Roller
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.
Transition Roller
Large capacity, long-distance, high belt tension, and important conveyors should generally be equipped with transition sections.
Return Idler
The return roller, also known as the parallel lower roller, is the most commonly used type of lower roller.
Self Aligning 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.
Frequently Asked Questions
What is the main function of an idler roller in a belt conveyor?
The idler roller supports the conveyor belt and the material being transported, reduces friction, and ensures the belt runs smoothly and stably along the conveyor frame.
What is the standard groove angle for a groove type idler roller?
The standard groove angle for a groove type idler is 35 degrees, which is the most commonly used angle across various conveyor systems, including the 35-degree groove type forward leaning idler.
When should a 45-degree groove type buffer roller be used?
A 45-degree groove type buffer roller can be used in sections of the guide groove that are not affected by material impact. For canvas conveyor belts, only 35-degree groove type buffer rollers should be selected.
What types of conveyors require a transition roller section?
Transition rollers are generally recommended for large-capacity, long-distance, high belt tension, and other important conveyor applications where smooth belt transition is critical.
What is the purpose of a self-aligning roller?
Self-aligning rollers are designed to automatically correct excessive lateral deviation of the conveyor belt during operation, preventing belt misalignment and ensuring the conveyor runs normally and safely.
What are the different types of self-aligning rollers available?
Self-aligning rollers come in three main types: ordinary self-aligning rollers, friction self-aligning rollers, and conical self-aligning rollers, each suited to different conveyor operating conditions and belt deviation correction requirements.
