Important part that affects the life of the conveyor belt - idler

- Jun 28, 2019-

Today, Ming Cheng introduces you to the rollers in the conveyor parts. In addition to the conveyor belt, the rollers are also important parts.


        As the important device of the belt conveyor, the conveyor idler costs 35% of the belt conveyor and withstands at least 70% of the resistance. Therefore, the quality of the roller is very important.


        There are many types of conveyor rollers, and the number is large. Divided by material can be divided into: ceramic roller, nylon roller, rubber roller and insulated roller; can also be divided into: groove roller set, all kinds of parallel roller set, all kinds of self-aligning roller set , all kinds of buffer roller sets.

Conveyor roller

Roller classification:


       1. The conveyor buffer roller can be divided into a spring plate type roller, an adjustable elastic type roller, a hanging type idler, a buffer ring type idler, a strong buffer type idler, and the like;


       2. The conveyor centering roller can be divided into a general-purpose cone roller, a spiral roller, a friction reversible roller, a powerful roller, a combined roller, and the like;


       3. Conveyor parallel rollers can be divided into ordinary type idler, steel rubber idler type, spiral type idler, comb type idler, forward tilt type idler, etc.;


       4. Conveyor trough-shaped idler can be divided into ordinary type idler, forward-tilt type idler, three-chain idler, reversible idler, transitional idler, V-type idler, hanging type idler, quick-change bearing Type roller, variable groove angle roller, etc.;

Roller classification:

The main function of the rollers is to support the weight of the conveyor belt and the load carrying goods. The rollers must remain flexible and secure during transport.

       The quality of the idler can be seen from several aspects: the flexibility of the idler, the amount of axial turbulence, and the radial runout of the idler.


       The roller is a small part in the belt conveyor, its mechanism is very simple, but it is not easy to manufacture a high quality roller, and the quality of the roller and the maintenance of the conveyor belt are used. The term has a very important meaning, reducing the friction between the idler and the conveyor belt, and plays an important role in the life of the conveyor belt, which accounts for more than 25% of the total cost of the conveyor.
