How To Maintain Jaw Crusher

2024-7-18

Jaw crusher, as an important crushing equipment in mining, plays a crucial role in primary crushing, thus prolonging its service life and reducing the occurrence of failures,

Ensuring its long-term stable operation and improving work efficiency, daily maintenance is a very important part. Below are some key maintenance measures for your reference.

1、 Regular inspection and maintenance

Check the heating condition of the bearings:

The temperature of rolling bearings should not exceed 70 ℃, and the temperature of sliding bearings should not exceed 60 ℃.

If the bearing temperature is found to be too high, the vehicle should be stopped immediately for inspection and troubleshooting.

Lubrication system inspection:

Ensure that the lubrication system is functioning properly and without any impact noise.

Observe the value on the oil pressure gauge and check the oil level in the tank and whether the lubrication system is leaking oil.

Regularly inject oil, such as adding oil to the suspension bearings and elbow heads of the moving jaw, adding oil to small crushers every 40-60 minutes, and dripping oil into the elbow heads of the elbow heads every 3-4 hours.

Regularly replace the lubricating oil in the fuel tank, usually every six months, and check whether the oil contains metal powder or other dirt. If there is any dirt, stop the vehicle and disassemble the bearings and other parts for inspection.

Check bolts and connectors:

Regularly inspect all bolts and flywheel keys and other connecting components for looseness, and tighten them in a timely manner.

Wear condition inspection:

Regularly check the wear condition inside the machine, such as the wear degree of the cone cap, impeller upper and lower channel liners, circumferential guard plate, and wear-resistant block.

Timely replace components with severe wear and repair them.

Conveyor belt inspection:

Regularly adjust the tightness of the conveyor belt to ensure even force distribution.

If the wear of the drive belt is found to be too severe, it should be replaced in a timely manner.

2、 Cleaning and maintenance

Cleaning equipment:

Regularly clean equipment, including cleaning machine surfaces, pipelines, inlet and outlet ports, vibrators, etc., to ensure the hygiene and ventilation of the equipment.

Replace vulnerable parts:

Regularly replace vulnerable parts such as jaw plates, hammers, etc. to avoid equipment failure and extend the service life of the equipment.

3、 Professional maintenance and upkeep

Configure professional technical personnel:

Jaw crusher is a relatively complex equipment that requires professional technical personnel for maintenance and upkeep.

Professional technicians should regularly inspect, clean, lubricate, replace vulnerable parts, and promptly handle equipment failures.

Establish maintenance records:

Establishing sound maintenance records can help enterprise managers better understand the maintenance status and effectiveness of equipment, and make timely adjustments and improvements.

4、 Precautions

Follow the operating procedures:

The jaw crusher must strictly follow the operating procedures and maintenance system during use.

Reasonable feeding:

The jaw crusher must be in good working condition before it can start feeding.

When adding materials, the crushed stones should be evenly added to the crushing chamber, not too much or too little.

Prevent overload:

Avoid long-term overload operation of equipment to reduce wear and tear and malfunctions.

In summary, the maintenance of jaw crushers involves multiple aspects, including regular inspection and maintenance, cleaning and maintenance, professional maintenance and maintenance, and precautions. Through comprehensive maintenance measures, the long-term stable operation and efficient work of the jaw crusher can be ensured.
