Line crushers are machines used to reduce the size of materials such as limestone, granite, or other types of rock and minerals. They are commonly used in mining, construction, and aggregate industries. Here are the main types of line crushers:
—
1. Jaw Crushers
– Description: Jaw crushers use compressive force to break down materials. They have a fixed jaw and a movable jaw that crushes the material against the fixed jaw.
– Applications: Primary crushing of hard and abrasive materials like limestone.
– Advantages: Simple structure, reliable operation, and high efficiency.
—
2. Impact Crushers
– Description: Impact crushers use impact force to crush materials. They have hammers or blow bars that strike the material, breaking it into smaller pieces.
– Applications: Secondary or tertiary crushing of medium-hard materials like limestone.
– Advantages: High reduction ratio and good cubical shape of the final product.

3. Cone Crushers
– Description: Cone crushers use a rotating cone-shaped mantle within a concave bowl to crush materials. The material is compressed between the mantle and the bowl.
– Applications: Secondary or tertiary crushing of hard and abrasive materials like limestone.
– Advantages: High efficiency, uniform particle size, and low operating costs.

4. Hammer Crushers
– Description: Hammer crushers use rotating hammers to strike and break down materials. They are often used in combination with a grate or screen to control the size of the output.
– Applications: Crushing soft to medium-hard materials like limestone.
– Advantages: Simple design, high production capacity, and low maintenance.

5. Roll Crushers
– Description: Roll crushers use two rotating cylinders (rolls) to crush materials by compression. The material is fed between the rolls and crushed as it passes through.
– Applications: Crushing medium-hard materials like limestone in smaller operations.
– Advantages: Low cost, mini
fines production, and uniform particle size.

6. Gyratory Crushers
– Description: Gyratory crushers consist of a conical head that gyrates within a larger conical chamber. The material is crushed between the gyrating head and the stationary chamber walls.
– Applications: Primary crushing of large quantities of hard materials like limestone
