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.

Drive System: The drive system of the compound crusher typically consists of an electric motor, V-belt drive, and pulleys. The motor drives the rotor to rotate, providing the necessary power for crushing the material.

Lubrication System: Compound crushers require proper lubrication to ensure smooth operation and prolong the service life of the bearings and other moving parts. A lubrication system is typically integrated into the crusher design to provide continuous lubrication to critical components.

Safety Devices: Safety devices such as overload protection systems and emergency stop buttons may be incorporated into the compound crusher to prevent damage to the crusher and ensure operator safety in case of unexpected events.

Overall, the internal structure of a compound crusher is designed to efficiently crush materials while ensuring durability, reliability, and safety. By combining the principles of hammer crushers and impact crushers, compound crushers offer advantages such as high crushing efficiency, uniform particle size distribution, and versatile application in various industries.
