What are the internal structure of the compound crushers?

Compound crushers, also known as composite crushers or combination crushers, are designed to crush materials efficiently by combining the advantages of both hammer crushers and impact crushers. They typically consist of several main components, each serving a specific function within the internal structure of the crusher.

Main Frame: The main frame of the compound crusher provides structural support and houses the other components of the crusher. It is usually made of welded steel plates or cast steel for strength and durability.

Rotor Assembly: The rotor assembly is a key component responsible for the crushing action in the compound crusher. It consists of a rotor shaft, rotor discs, and hammer bars or impact elements. The rotor rotates at high speed, impacting the material fed into the crusher chamber.

Crushing Chamber: The crushing chamber, also known as the crushing cavity or crushing chamber, is the space where the material is crushed by the rotor. It is typically lined with wear-resistant liners to protect the crusher housing from abrasion and wear.

Feed Hopper: The feed hopper is located above the crushing chamber and serves as the entry point for the material to be crushed. It allows for controlled feeding of the material into the crusher, ensuring efficient operation and preventing overloading.

Adjustable Discharge Opening: Compound crushers often feature an adjustable discharge opening or gap between the rotor and the crushing chamber. This allows for the adjustment of the final product size by controlling the size of the crushed material that exits the crusher.
