How to match the idler of belt conveyor?

The core of belt conveyor idler collocation is to divide the work according to the function of conveying section, select the type according to the material characteristics and set the specifications according to the bandwidth. A complete collocation scheme is as follows:

Bearing section (upper idler)

Trough idler for ordinary bulk materials, generally with a groove angle of 35, meets the requirements of conventional transportation;

Buffer rollers for bulk materials and mine coal gangue are installed at the blanking port to absorb shock and prevent smashing;

Self-aligning idler is installed at the position where the belt is prone to deviation, and one set of grooved idler is equipped every 10 groups to automatically correct deviation.

Return section (lower idler)

Normally, parallel idler is used to support the belt return;

In the scene with much dust and serious material sticking, the spiral idler is used with its own cleaning function to prevent the belt from sticking to the material.

Spacing collocation

Light materials: the spacing between grooved rollers is 1.2～1.5m, and the spacing between return rollers is 2 ~ 3m;

Medium and heavy load, coal, ore: the spacing between grooved rollers is 0.8～1.0m, and the blanking holes are densely arranged.

Specification matching

The diameter and length of the idler must correspond to the belt width, conveying capacity and belt speed.

Bearing and sealing structure are selected according to the environment: indoor common seal, underground and open-air multiple labyrinth seal.

Reasonable collocation can reduce resistance, reduce deviation, prolong the life of belt and idler, and improve the running stability of the whole machine.
