Structural Features of Compound Crushers

Compound crushers are medium-to-fine crushing equipment widely used in mining, building materials, metallurgy, chemical, and other industries. Combining the advantages of multiple crushing principles, they feature compact structure, high crushing efficiency, low energy consumption, and uniform product particle size.

Key Structural Features of the Compound Crusher

Vertical Shaft Design: The core component is a vertically mounted main shaft that drives the rotor to rotate at high speeds.

Rotor: Typically featuring an integral or modular structure, it is equipped with wear-resistant throwing heads or hammers, serving as the key component for delivering impact energy.

Vortex Crushing Chamber: A ring-shaped space surrounding the rotor, designed with a vortex-like configuration. Materials undergo high-speed rotation, collision, and crushing within this chamber, serving as the primary zone for laminar crushing.

Impact Plates/Liner Plates: Installed on the inner walls of the crushing chamber, these are adjustable or replaceable. Their shape and angle influence material flow and crushing efficiency.

Feed Hopper: Guides materials into the crushing chamber.

Discharge Opening: Located at the bottom, where crushed material exits. Some models allow adjusting the discharge gap by repositioning the impact plate or adding/removing shims to fine-tune product particle size.

Drive System: Typically driven directly by an electric motor via a pulley or coupling to the main shaft.

Base/Frame: Supports the entire equipment.
