Working principle of 69 crusher

The 69 crusher, also known as a cone crusher, is a type of crushing equipment used in the mining, quarrying, and aggregates industries. It is named after its design, which has a 60-degree cone angle and a 9-inch (229 mm) diameter crushing cavity. The working principle of a 69 crusher involves the movement of a mobile cone against a fixed cone, creating a crushing action that breaks the raw material into smaller particles.

The main components of a 69 crusher are:

1. Cone body: The cone body is the main structure that holds the crushing cavity and supports the mobile cone. It is typically made of heavy-duty steel to withstand high-pressure crushing forces.

2. Mobile cone: The mobile cone is a truncated cone mounted on a pivot point that allows it to swing in a circular arc. As it rotates, the mobile cone moves towards the fixed cone, creating a crushing action on the raw material.

3. Fixed cone: The fixed cone is a stationary truncated cone that forms the crushing cavity with the mobile cone. The material is crushed between the two cones as the mobile cone rotates.

4. Crushing cavity: The crushing cavity is the space between the mobile and fixed cones where the raw material is crushed. The size and shape of the cavity determine the final particle size of the crushed material.

5. Discharge opening: The discharge opening is located at the bottom of the crushing cavity and allows the crushed material to exit the machine. The opening can be adjusted to control the particle size of the output.

6. Drive system: The drive system powers the rotation of the mobile cone, usually using a motor or hydraulic system.

7. Support structure: The support structure secures the 69 crusher to the foundation, ensuring stable operation during the crushing process.

The working principle of a 69 crusher involves the following steps:

1. The raw material is fed into the crushing cavity through a hopper or feeder.

2. As the mobile cone rotates, it swings towards the fixed cone, creating a crushing action on the material.

3. The raw material is gradually crushed and ground between the two cones, becoming smaller particles.

4. The crushed material is discharged through the discharge opening, and the size of the particles can be controlled by adjusting the opening size.

5. The material is then conveyed to the next stage of the crushing process or stored for use in various applications.

The 69 crusher's ability to produce consistently sized particles makes it a popular choice for crushing applications in many industries, including mining, quarrying, construction, and aggregates.
