The sudden shutdown of the mineral processing equipment during the operation process not only affects the production efficiency of the beneficiation production line, but also has great harm to the mineral processing equipment. Therefore, in the case of sudden shutdown of the beneficiation equipment, it is necessary to find the cause as soon as possible, and choose the appropriate solution for the cause. Let's take an example of a solution to the downtime failure of a jaw crusher during operation.

The main reasons for the sudden shutdown of the jaw crusher during operation are:

1. The discharge port is blocked, causing full cavity blocking.

2. The V-belt that drives the sheave rotates too loose, causing the belt to slip.

3. The eccentric shaft tightening bushing is loose, causing no gap on both sides of the bearing housing of the frame, so that the eccentric shaft is stuck and cannot be rotated.

4, the work site voltage is too low, the host encountered a large material, unable to break.

5. Bearing damage.

Because there are many reasons for the failure of the jaw crusher during the operation process, in the daily work process, the elimination method is usually adopted to solve the sudden shutdown of the jaw crusher.

1. Remove the blockage at the discharge opening to ensure unobstructed discharge.

2. Tighten or replace the V-belt.

3. Reinstall or replace the adapter bushing.

4. Adjust the voltage of the work site to meet the requirements of the working voltage of the host.

5. Replace the bearing.
