Application of Primary Rock Crusher:
The series of limestone crusher can reach the crushing ratio of 4-6 and the shape of final product is even. They are widely applied to crush high hardness, mid hardness and soft rocks and ores such as slags, construction materials, marble, etc. The pressure resistance strength is under 200Mpa, that is, suitable for primary crush. They can be used in mining, metallurgical industry, construction, road and railway building, conversancy, chemistry, etc.

Primary Rock Crusher-Operating principle:
This machine uses motor as its power. Through the motors wheels, the eccentric shaft is driven by the triangle belt and slot wheel to make the movable jaw plate move by a regulated track. Therefore, the materials in the crushing cavity composed of fixed jaw plate, movable jaw plate and side-lee board can be crushed and discharged through the discharging opening.

Choose the Suitable Primary Crusher
A rock jaw crusher is generally used as a primary crusher in a crushing circuit. It has higher output by comparing with other crushers. Product is fed into the top of the jaw crusher by a vibrating grizzly feeder.
The eccentric rotating drive shaft causes the movable jaw to oscillate crushing the aggregate against a fixed jaw. Jaw crushers are run on belt drives driven by an electric motor or diesel engine. Jaw crushers are used extensively throughout the aggregate and mineral processing industry. We offer jaw crusher units, modular and portable jaw crusher assemblies and entire crushing plants.
