Jaw crushers has stationary jaw crusher, portable jaw crusher and mobile jaw crusher (crawler jaw crusher). Jaw crusher (FSK Series) is not only able to be used together with mine-selecting and gravel processing equipments but also be used independently. Jaw crusher is used for Primary crushers and Secondary crushers for crushing all kinds of minerals and rocks.

We, Samyoung plant, also manufactures single toggle jaw crushers with stationary and portable jaw crushers.

As a leading manufacturer of full set of crushing and screening equipment in Korea, based on years' experiences and researches Samyoung plant has produced Jaw crusher (FSK Series) which is one kind of efficient and energy-saving rock crushers. Wherein, large and medium-size stone jaw crushers are our competitive products; especially in designing and producing large-sized jaw crusher, we have already ranked the first place in Korea jaw crushers and foreign jaw crusher.

Jaw crusher (FSK Series) is designed with years of experience in manufacturing various types of crushers and manufactured with our finest workmanship. Jaw crushers (FSK Series) are widely used not only in mines and chemical plants but in stone aggregate and limestone crushing plants.

Jaw Crushers Working Principle

Jaw crusher is driven by a motor, and the moving jaw moves up and down via eccentric shaft. The angle between fixed jaw and moving jaw becomes smaller when the moving jaw runs down, then the materials are crushed into pieces. It will become bigger when the moving jaw runs up. The moving jaw plate leaves the fixed jaw plate under the action of pole and spring, and then the end products come out from the crushing cavity. And also, Jaw crusher is used as both Primary jaw crusher and Secondary jaw crusher.

Jaw Crushers Benefits and Features

Jaw Crusher Maintenance

If attention is paid to the followings, jaw crusher can better run and extend the life.

before the operation or maintenance of jaw crusher, make sure you have studied manual and received training in safe operation. To determine if the accident happens, you know how to turn off the machine.

maintenance of jaw crusher equipment should use a qualified parts and the right tools

Use the lubricant recommended instructions

to report to their superiors any anomaly related equipment

Before the maintenance of jaw crusher machine, all electrical control devices and electric motors should be power outages, locked, and posted with maintenance of identity.

When the equipment operation, not to carry out lubrication, cleaning, repair or maintenance work

For risk markers do not operate switches or valves
