In cement plants, various types of crusher machines are used to crush raw materials into smaller particles suitable for the cement manufacturing process. The primary types of crusher machines used in cement plants include:
1. Jaw Crushers:
- Function: Used for the primary crushing of limestone, boulders, and other large-sized materials.
- Operation: They operate on the principle of compressive forces. Materials are fed into a V-shaped jaw and crushed as they are compressed between a fixed and a moving jaw.
2. Gyratory Crushers:
- Function: Also used for primary crushing. They handle larger capacities and are suitable for crushing large, hard rocks.
- Operation: The crushing chamber has a concave surface and a conical head, both of which are lined with manganese steel. The rocks are crushed by the closing gap between the moving piece (cone) and the static piece.
3. Impact Crushers:
- Function: Typically used for secondary crushing of softer materials such as limestone. They can also be used for primary crushing if the rock is not too hard.
- Operation: These crushers utilize impact rather than pressure to crush materials. The material is fed into the chamber and is struck by rotating hammers or bars which force the material to break apart.
4. Hammer Crushers:
- Function: Used for both primary and secondary crushing, especially of brittle and soft materials like limestone and clay.

- Operation: Materials are crushed by the impact of high-speed rotating hammers. The crushed material is then thrown against a breaker plate and shattered.
5. Cone Crushers:
- Function: Used for secondary and tertiary crushing stages. Suitable for medium-hard to hard and abrasive materials.
- Operation: The materials are squeezed and crushed between a moving cone (mantle) and a fixed cone (bowl liner).
6. Roller Crushers:
- Function: Used for both primary and secondary crushing. They are more suitable for friable materials.
- Operation: The material is drawn into the gap between two rollers rotating in opposite directions and is crushed by compression and shear forces.
Each of these crushers has its specific use case depending on the hardness, size, and other properties of the raw materials, as well as the stage in the cement production process. Proper selection and operation of these crushers are essential for ensuring efficiency and optimizing the overall production process in a cement plant.
