What are the commonly used types of equipment for crushing stones? Stone crusher

The commonly used types of equipment for crushing stones, often referred to as stone crushers, include:

1. **Jaw Crusher**: This is one of the most widely used types of stone crushers. It is primarily used for medium-grained crushing of various ores and medium-hard materials. The crushing process takes place between a fixed jaw and a moving jaw. The final product has a cube-like shape and high crushing efficiency.

2. **Cone Crusher**: Cone crushers are mainly used for medium and fine crushing of various ores and rocks. The crushing cavity is formed by the spindle, eccentric sleeve, and concave. The material is crushed by the squeeze and grind action. Cone crushers are available in various types, such as spring cone crusher and hydraulic cone crusher.

3. **Impact Crusher**: Impact crushers are suitable for shaping and secondary crushing of various ores and rocks with medium hardness. They work by impact rather than compression. The materials are crushed by the high-speed impact of the moving hammer or impact plate on the fixed screen board.

4. **Hammer Crusher**: Hammer crushers are mainly used for medium and fine crushing of medium-hardness materials, such as coal, salt, gangue, and other materials with weak corrosivity. The crushing process relies on the impact force of hammers.

5. **Roll Crusher**: Roll crushers are typically used for medium and fine crushing of medium-hardness materials, such as gangue, coal, and other materials. The material is crushed by the extrusion force generated between two rolls.

6. **Double Roll Crusher**: This type of crusher is mainly used for medium and fine crushing of medium-hardness materials, such as clinker, coal, and other materials. It has a higher crushing pressure and is suitable for materials with a moisture content of less than 6%.

7. **Trapezium Mill**: This is a type of Raymond mill and is mainly used for medium and fine powder processing of various non-flammable and non-explosive mineral materials with Mohs hardness less than 9 and humidity less than 6%.

8. **Ultra-fine Grinder**: Ultra-fine grinders are used for ultra-fine powder processing of various non-flammable and non-explosive materials with Mohs hardness less than 9 and humidity less than 6%. The particle size of the finished product can reach 3000 mesh.

These are just a few examples of the equipment used for crushing stones. The specific type of crusher used will depend on factors such as the hardness and humidity of the material, the required output particle size, and the production capacity.
