Discover the best practices for designing a successful stone crusher plant, including factors to consider, equipment selection and configuration, environmental management, and safety and maintenance priorities. Learn how to optimize crushing operations and minimize environmental impact for efficient and effective production.
Starting from the base working principle that compression is the forcing of two surfaces towards one another to crush the material caught between them.Impact crushing can be of two variations: gravity and dynamic. An example of gravity impact would be dropping a rock onto a steel plate (similar to what goes on into an Autogenous Mill).
If you're in the market for a cone crusher, it's important to understand the machine's working principle to make an informed decision.

When the cone crusher is in operation, the spindle rotates around its own axis, causing the mantle to move back and forth. The mantle is the cone-shaped part of the crusher that moves in a circular motion against the concave, which is the stationary outer surface of the crusher. The material enters the crusher through the top of the hopper …
Place the crusher where it makes most sense, Dobler says. Also, consider if a portable setup is the way to go and what type of crusher matches your rock's needs.
