Are you in search of high-performance crushing equipment, or looking to learn about the operational principles of mining and construction crushers? This guide details all mainstream crusher types and their features. It also introduces MP premium PEV series jaw crushers, helping you select suitable machines for processing granite, basalt, iron ore and other hard rocks.
Types and Working Principles of Mainstream Crushers
1. Jaw Crusher
Core Components: Fixed jaw plate, movable jaw plate, toothed liner, eccentric shaft, toggle plate and frame.
The movable jaw plate performs reciprocating swing. It approaches the fixed jaw plate to crush materials via combined compression, splitting and bending forces.
Two basic designs are available: simple swing jaw crusher and complex swing jaw crusher. The motor drives the eccentric shaft, which converts rotational motion into reciprocating movement of the movable jaw. Materials are crushed when the jaw closes. Once the jaw retracts, finished products discharge from the crushing chamber under gravity.
2. Cone Crusher
Core Components: Stationary outer cone, eccentric rotating inner cone, mantle and concave.
The inner cone operates with eccentric gyratory motion. Materials undergo compression and shear between the two cones. This equipment is widely applied for secondary and tertiary crushing of hard ores.
3. Hammer Crusher
Core Components: Rotor, hinged hammers and grate screen.
High-speed rotating hammers impact and crush incoming materials. Crushed materials are delivered to the bottom grate screen, and qualified products are discharged through screen openings. This machine is well suited for medium-hard and brittle materials.
4. Impact Crusher
Core Components: Rotor, rigid blow bars and impact plates.
Blow bars rotate at high speed to break materials by impact. Materials are then thrown onto impact plates for secondary crushing. Mutual collision between particles further refines material size, and final products exit from the machine bottom. It produces materials with ideal grain shape, and is widely used for aggregate production.
5. Vertical Shaft Crusher
This category includes vertical shaft hammer crusher and vertical shaft impact crusher.
It adopts similar core structures and working principles as conventional hammer and impact crushers. Two sets of rotors conduct staged crushing. Materials enter through the top hopper, and go through primary and secondary crushing successively before free discharge from the base. Its compact structure makes it ideal for medium and fine crushing operations.
6. Vertical Shaft Impact Sand Maker
Core Components: High-speed rotating impeller, central feeding pipe and annular liner.
Also known as vertical shaft impact crusher, it receives materials through the central feeding pipe. Materials fall to the impeller center and are accelerated along internal channels, then collide with surrounding liners for crushing. As key equipment for manufactured sand production, it also delivers reliable material shaping performance.
7. Roll Crusher
Core Components: A pair of counter-rotating crushing rollers.
The two rollers rotate in opposite directions, drawing materials into the roller gap for extrusion crushing. Equipped with a forced discharge structure, it maintains stable output size and effectively prevents blockage. It is commonly used for medium crushing and processing of abrasive materials.
Introduction to MP PEV Series Jaw Crusher
MP PEV series jaw crushers consist of two product lines. All models are designed for efficient crushing of various hard rocks.
- Standard General Models: PEV110, PEV125 and PEV140, applicable to large stationary crushing lines.
- Mobile Plant Models: PEV96 and PEV106, specially developed for small mobile crushing stations.
Key Advantages
Excellent Overall Performance
- This series features high output capacity, large crushing ratio and low wear loss, and can handle materials with large feed size. The uniquely designed deep V-shaped crushing chamber maximizes production efficiency, and effectively reduces the replacement cost of wear parts.
- Robust and Durable Structure
- The heavy-duty integrated movable jaw assembly is fabricated from high-quality cast steel with strong load-bearing capacity. Large pulleys and flywheels ensure stable operation and consistent power transmission. The modular weld-free frame and integrated motor mounting structure eliminate stress concentration and save installation space.
- Convenient and Safe Adjustment
- The unit is fitted with a wedge-type discharge opening adjustment system. Compared with traditional shim adjustment, it delivers simpler operation, higher safety and improved daily maintenance efficiency. Application Scope
Jaw crushers are widely utilized in mining, metallurgy, construction, highway, railway, water conservancy, chemical and other industries. They are used for primary and secondary crushing of ores and rocks with compressive strength up to 300 MPa. MP PEV series jaw crushers are the preferred solution for primary crushing in various production lines.
