The working principle of KMH 440 Cone crusher is based on the compression crushing process. These machines are used to break large chunks of material into smaller, more manageable pieces. Here’s a step-by-step explanation of the typical operating principles of cone crushers:

1. Material Feed:
   • Raw material, often rocks or minerals, is fed into the crusher from the top.
2. Crushing Chamber:
   • The material enters a crushing chamber, typically shaped like a cone or a bowl.
3. Mantle and Concave:
   • Inside the crushing chamber, there are two main components: the mantle and the concave. The mantle is mounted on an eccentrically rotating spindle.
4. Eccentric Rotation:
   • The spindle, which is eccentrically mounted, gyrates within the concave. This eccentric motion creates a compression crushing action.
5. Crushing Process:
   • As the mantle gyrates, it compresses the material against the stationary concave. This action breaks the material into smaller pieces.
6. Adjustment of the Gap:
   • The gap between the mantle and the concave can be adjusted. This adjustment controls the size of the crushed material, allowing for the production of different-sized end products.
7. Release of Crushed Material:
   • Once the material reaches the desired size, it exits the crushing chamber through the bottom opening.
8. Hydraulic System (if applicable):
   • Some modern cone crushers are equipped with hydraulic systems. These systems can be used to adjust the crusher settings, control the size of the crushed material, and clear any potential blockages.
9. Continuous Process:
   • The process is continuous as long as there is material to be crushed. The cycle of feeding, crushing, and discharging is repeated, providing a continuous flow of crushed material.
10. Cone Crusher Types:
    • There are different types of cone crushers, including standard cone crushers, short head cone crushers, and compound cone crushers. Each type is designed for specific applications and may have variations in their operating principles.

It’s important to note that the specific design and features of cone crushers can vary between manufacturers and models. Additionally, advancements in technology may introduce variations or additional features in newer models. For detailed information on a specific cone crusher, it’s recommended to refer to the manufacturer’s documentation and user manuals.
