BTMA–What should I do when the temperature of the jaw crusher machine bearing becomes too high while it is running?

jaw crusher

The jaw crusher machine features large crushing ratio, uniform product sizes, simple structure, reliable operation, easy maintenance, low operating costs, and easy upkeep. Jaw crushers are used extensively in mining, smelting and building materials, highways and railways, water conservancy, chemical industries, and many other sectors. They crush various materials with a compressive force of no more than 320 MPa. The jaw crusher’s shaft bears the whole load of the machine and plays an important role in its normal operation. It is important to check that the jaw crusher’s bearings are operating properly during its operation. Jaw crusher bearings can fail when the temperature gets too high. What should you do if your jaw crusher parts heat up too much?

1. The jaw crusher machine bearing is either out of oil, or too much oil.

It’s easy: Just read the manual and fill the oil according to the regulations.

2. There is no way to add oil because the oil hole is closed.

The solution is simple: Turn off the oil tank and clear the blockage.

3. The flywheel counterweight’s position is off-track and the frame jumps.

To stabilize the frame, adjust the flywheel counterweight position.

4. There is an axil movement in the tightening bushing.

The solution is simple: Remove the bearing cover from the frame, tighten your fixed bushing, and then remove or replace the flywheel.

5. Bearing wear and cage damage

The solution is simple: Repair or replace bearings and/or cages.

6. Non-bearing reasons

Friction, heat generation and heat generation between movable jaw seal sleeves and the end cover, or the double embedded covers of the frame bearing seats rotates with main shaft, friction, heat generation and temperature rise.

Simple solution: Replace the end cover and sealing sleeves, or loosen up the upper bearing cover at the heating end of your bearing housing. Then press the embedded cover into the bearing seat groove, along with the fuse, and then fix it to the bearing cover.
