Stone crusher repair and maintenance

The repair and maintenance of the crusher is the key to ensure its normal operation and extend its service life. Repair and maintenance work includes daily maintenance, minor repairs, medium repairs and overhauls, as well as specific maintenance measures based on the type of crusher (such as gyratory crusher, jaw crusher, mobile crusher, cone crusher, etc.).

Daily maintenance:

Includes checking the bearing lubrication, fasteners, drive belt or pulley status, ensuring the integrity of the protective device, cleaning the material or debris in the damaged cavity, and checking the correctness and integrity of the hydraulic system. ‌
Minor repair:

Involves inspection and repair of adjustment devices, adjustment of discharge port clearance, repair of worn linings and transmission components, cleaning of equipment and adjustment of lubrication systems. The inspection cycle of minor repairs is usually two weeks to one month. ‌
Medium and overhaul:

Medium repairs include all the maintenance content of minor repairs, and replace damaged structures such as tie rods, bushings, etc. Overhaul includes all the content of medium repairs, replaces damaged eccentric shafts, inspects and replaces worn parts and component structures to achieve the purpose of technological innovation. The maintenance cycle of medium repair is usually once a year, and there is no specific cycle for overhaul, which depends on the equipment conditions.
Maintenance of specific types of crushers:

Gyratory crushers need to pay attention to the hazards of iron, and reduce the entry of iron parts through technical improvements such as installing metal detectors, and classify and store and handle iron parts at the production site. ‌
Cone crushers emphasize the importance of feeding devices, as well as the inspection and maintenance of linings to ensure uniform distribution of feed, reduce power loss and lining wear. ‌
Mobile crushers need to pay attention to bearing lubrication, equipment cleaning and keeping the lubrication system in good condition.
Seasonal maintenance:

In winter, special attention should be paid to the selection and replacement of oil, select fuel and engine oil suitable for low temperature conditions, and replace lubricating oil and grease to ensure the normal operation of equipment under cold conditions. ‌
Comprehensive inspection and maintenance:

Regularly conduct comprehensive equipment inspections, including electrical systems, hydraulic systems, mechanical components, etc., and repair problems in a timely manner to ensure the normal operation and safety of equipment. ‌
In summary, the repair and maintenance of crushers is multifaceted, and it is necessary to formulate a suitable maintenance plan based on the specific type and use conditions of the equipment, and perform maintenance regularly to ensure the normal operation of the equipment and extend its service life.
