How to maintain jaw crusher?


Nowadays, jaw crusher is widely used in the crushing and mining industry, and it is very important to maintenance and repair the jaw crusher regularly. We would like to introduce some tips for the maintenance and repair works of jaw crusher as follows:

1.       Shut down the jaw crusher and check it regularly. Check the wear degree of the spare parts and change them if needed;

2.       Check the transmission belt regularly. Adjust the tightness of the transmission belt to avoid the uneven stress distribution. Change the transmission belt if it wears out.

3.       Lubrication works of the components. Inject appropriate amount of lubrication grease every 100 working hours; clean the bearing every 2000 working hours; change the bearing every 7200 working hours;

4.       Minor repair mainly includes adjusting the discharge opening; changing the wear-out parts; repair the transmission part; injecting the lubrication oil and grease and so on. And the period of the minor repair is one to three months;

5.       Medium repair includes changing the toggle plate, liners and so on. The period is one to two years;

6.       Major repair includes changing the eccentric shaft of the movable jaw. The period is five years.

How to run a complete crushing plant?

After setting up the stone crushing plant, the most important thing is the daily operation of it. We would like to show you how to run the whole stone crushing plant in a right way as follows:

1. Inspect all the parts of the rock crusher before operation and make any repairs or add lubrication where needed. Check for broken teeth, bolts and belts and make sure there are no obstructions in the stone crushing cavity.

2. Turn on the engine of the rock crusher and listen to make sure that it is operating properly.

3. Start the crushing mechanism of the stone crusher to make sure all components are operating smoothly. Shut down the machine and make repairs where necessary.

4. Set the crusher up under a conveyor belt that can carry crushed rock to a pile or dump truck.

5. Adjust the opening of the stone crusher to accommodate the size of the stones you will be crushing. If you leave the opening too wide, your machine will be performing excessive work, leading to unnecessary wear on your stone crusher.

6. Feed large stones into the cavity of your stone crusher with a crane or conveyor belt and allow the machine to do the work.

7. Feed crushed stones into a secondary stone crusher to achieve smaller rocks, if desired. If you use a jaw crusher, you may need to use a roller crusher to produce gravel-sized rocks.

8. Turn off the power to the machine and inspect its parts to make sure there are no stones lodged in the stone cavity.
