What are safe and effective ways to operate a jaw crusher and some tips for maintenance?

As we all know that jaw crusher is the necessary equipment in stone processing line. It is widely used in mining, construction, road building industry and so on. Jaw crusher has high crushing ratio and large capacity, but the structure is simple. To keep the jaw crusher running normally, there are some safe and effective operating rules the operator should follow.

Dos Before Starting The Crusher

Start the belt conveyor, and then start the jaw crusher without feed any raw material;

After the jaw crusher running regularly, start the feeder. If the operator found out some unusual sound, he should stop the crusher immediately and check the machine.

Dos In The Operation

The raw materials should be fed into the crusher evenly and continuously and the feed size of materials should be under the allowed ranges. When the feed opening blocks, the operator should stop the feeder, and remove the materials blocked in the feed opening.
