Working Principle of Compound Crusher

The compound crusher is a medium-fine crushing equipment widely used in mining, building materials, metallurgy, chemical, and other industries. It combines the advantages of multiple crushing principles, featuring compact structure, high crushing efficiency, low energy consumption, and uniform product particle size.

Core Working Principle of Compound Crusher

Vertical Shaft Impact Crushing: Material enters the high-speed rotating rotor through the top feed inlet (typically equipped with throwing heads or hammers). Under centrifugal force, the material is propelled outward at high speed.

Layer Crushing: The ejected material first impacts the impact plates (liner plates) surrounding the rotor, undergoing initial impact crushing. More significantly, the rebounded or splattered material undergoes multiple crushing cycles through high-speed collisions, compression, and grinding with each other in mid-air (self-lining/stone-on-stone crushing). .

Impact Crushing: Some material may also undergo impact crushing after striking the impact plates or the inner wall of the machine housing.

Combined Effect: These three crushing mechanisms—impact, laminar, and impact—occur simultaneously or alternately within the crushing chamber, working together to reduce the material to the desired particle size.
