The principle of a KMH 660 Cone crusher revolves around a central axis that is covered by a mantle, and the main shaft is inclined, allowing the crushing cone to rotate. When the crusher works, the mantle moves periodically, which generates compressive and bending forces on the material to be crushed. Here is a more detailed breakdown of the working principle of cone crushers:

1. Mantle and Concave:
   • The crushing chamber of the cone crusher is formed by the mantle and the concave. The mantle is fixed on the main shaft and is vertically positioned over the concave.
2. Eccentric Motion:
   • The main shaft, which is powered by the drive unit, is eccentrically positioned. This eccentricity causes the mantle to move in an eccentric pattern.
3. Compression Crushing:
   • As the mantle moves periodically, it compresses the material against the concave. This compression action breaks the material into smaller pieces.
4. Adjustable Gap:
   • The gap between the mantle and the concave, known as the crushing chamber, can be adjusted. This adjustment allows control over the size of the crushed material, enabling the production of different-sized end products.
5. Crushing Cycle:
   • The crushing process is continuous as the material continuously enters the crushing chamber and is progressively crushed until it reaches the desired size.
6. Release of Crushed Material:
   • Once the material is crushed to the desired size, it exits the crushing chamber through the bottom opening.
7. Hydraulic System (if applicable):
   • Some cone crushers are equipped with hydraulic systems for adjusting the crusher settings and clearing potential blockages. This enhances the efficiency and safety of the crushing process.

The principle of KMH 660 Cone crusher is based on the concept of squeezing the material between surfaces, and the compression KMH 660 Cone crusher action is effective for various types of materials, including hard and abrasive ones. The ability to adjust the gap between the mantle and concave is a crucial feature, as it allows for the production of different-sized end products, meeting the specific requirements of various applications.
