Structural characteristics of mining circular chain

A circular chain is made by welding multiple circular rings of the same size in sequence, which has good flexibility and wear resistance.

The uniform pitch of the circular chain ensures the smoothness of the chain during operation.

The interface of the circular chain is welded tightly to ensure the connection strength and reliability of the chain.

The mining circular chain can be selected with different diameters and pitches according to actual needs to meet the requirements of different working conditions.

Performance requirements for mining circular chain

High strength: The mining circular chain needs to have high tensile strength to meet the requirements of heavy-duty operations such as ore transportation and lifting.

Wear resistance: The circular chain generates friction with the ground, ore, etc. during operation, requiring the chain to have good wear resistance.

Fatigue resistance: The mining circular chain needs to have good fatigue resistance during repeated stretching and bending processes.

Corrosion resistance: The mining environment is complex, and the mining ring chain should have a certain degree of corrosion resistance to extend its service life.
