Maintenance and servicing of mobile crushers are key to ensuring normal operation and longevity

The introduction of mobile crushers has addressed significant drawbacks in the mining industry. In areas unsuitable for fixed production lines, mobile stations resolve issues related to site selection, infrastructure, and personnel for users. Mobile stations primarily feature the following characteristics: flexible relocation, convenient maintenance, and high production capacity, making them strongly recommended equipment for enhancing mobile crushing operations. How can the service life be extended and faults minimised during the use of mobile stations? Maintenance is one of the best methods. What methods should be employed for maintenance?

1. Equipment operators must undergo pre-employment training and pass an assessment before being allowed to operate the equipment. Unauthorised personnel who have not received training must not operate the equipment. Any issues that arise should be reported to the operators for resolution;

2. Personnel safety must be ensured during equipment operation. If the mobile crushing plant exhibits abnormalities while running, it must not be inspected while powered on. The machine should be shut down before any repairs or maintenance are conducted;

3. Lubricating oil and hydraulic oil must be purchased through official channels and used within their shelf life. During inspections, if hydraulic oil or lubricating oil is found to be degraded or insufficient, it must be replaced. After cleaning the original components, the required amount must be added—more is not necessarily better. Excessive addition can increase resistance in moving parts, reducing equipment efficiency;

4. Do not over-tighten fixed bolts. During operation, the equipment may experience minor vibrations, causing some fastening bolts to loosen. Inspect them before operation, and tighten any loose bolts, but do not over-tighten them. Over-tightening can cause equipment deformation or bolt aging, leading to cracks;

5. Maintenance schedules are not fixed. When maintaining a mobile crushing plant, follow the technicians' instructions for regular maintenance, keep maintenance records, and conduct inspections at the beginning and end of each shift.

The above are several issues summarised by the editor regarding the maintenance of mobile crushing plants. Operators should strictly follow the operating procedures and regulations for maintenance to avoid damage to personnel and equipment.
