The Correct Startup and Shutdown Method on Jaw Crusher

The Correct Startup and Shutdown Method on Jaw Crusher

As a crushing machinery, jaw crusher is widely used in various of industries, has advantages of simple structure, reliable operation, easy maintenance and low production cost etc.. The operation and maintenance of jaw crusher is very important, including operation to start and stop, because the correct operation help improve crusher production capacity.

Preparing work before driving:

Check whether the major part is intact, fastening bolts and other connectors for loose, safety devices are complete; check whether the feeding, transportation and electrical equipment and so on are in good condition; check whether lubricating device intact, the cooling water pipe valve is on.

Startup and normal operation:

Driving according to the operation procedures, which means the driving order is inverse production process;when start the main motor, please watch over the ammeter indication on control cabinet, after 20s - 30s, the current drops below normal operation current value; adjust and control feeding to make it uniform, besides material diameter should less than 80% - 90% of the width of the feed inlet; Generally,sliding bearing temperature should not exceed 60 degrees Celsius, the rolling bearing temperature should not exceed 60 degrees Celsius;when electrical equipment automatically tripping, if unexplained, prohibited forced consecutive starts; when there is a mechanical failure or accident, should stop immediately.

The correct parking operation

The stop order, in contrast to the drive order, namely along the direction of the production process operation; you can not absolutely stop the lubrication and cooling system before the crusher is stationary. moreover, circulating cooling water should be put off in winter to avoid bearing frost crack; Downtime to do the work of cleaning and inspection of machine parts.
