PRIMARY COMPRESSION CRUSHING OF ABRASIVE MATERIAL. If you can explain how a nutcracker works you can essentially envision the operation of a Liberty Jaw Crusher. Inside the chamber there are two jaws. One is fixed while the other constantly moves back and forth. This action compresses the rock causing it to break.
If the crusher is to be fed directly by a conveyor: All dangerous parts of machinery should be suitably guarded. Failure to replace guards (on crushers and conveyors) after cleaning or maintenance work is a major cause of injury on these machines. Fig. 2 Excavator feeding mobile stone crusher. Blocked crushers Causes
Raw material of various sizes are brought to the primary crusher by rear-dump haul units, or carried by a wheel front-end loader. Primary crushing reduces excavated rock to a more manageable size. There are different types of primary secondary and tertiary crushers including jaw crushers, gyratory crushers, impact crushers, and autogenous crushers.

Selecting the right primary crusher is foundational to success at a crushing site. The primary crusher is the engine that drives the rest of the plant; it's the workhorse that takes blast feed sizes and reduces them to sizes that are manageable for other site components – the belts, the screens, and eventually any secondary crushers – on the road to a finished product.
Rocksizer Jaw Crushers. RockSizer primary stage jaw crushers feature the upthrust toggle action which is also common to the StoneSizer range. Developed by Parker, this gives a slight downward movement to the swing jaw that promotes a forced feed and therefore increased output while at the same time minimising any rubbing action resulting in a well shaped product and reduced and even wear on ...

Gyratory crushers were invented by Charles Brown in 1877 and developed by Gates around 1881 and were referred to as a Gates crusher [1]. The smaller form is described as a cone crusher. The larger crushers are normally known as primary crushers as they are designed to receive run-on-mine (ROM) rocks directly from the mines.
Crusher Blockage. Clearing blocked jaw crushers can be very hazardous and many plant operators have been killed carrying out this task. Blockage incidents can be greatly reduced by supplying rock that is properly sized to match the primary jaw opening. Prevention of oversize in feed material starts at the face with good fragmentation.
A crusher is a machine designed to reduce large rocks into smaller rocks, gravel, sand or rock dust.. Crushers may be used to reduce the size, or change the form, of waste materials so they can be more easily disposed of or recycled, or to reduce the size of a solid mix of raw materials (as in rock ore), so that pieces of different composition can be differentiated.
