Cage Crusher


The Cage Crusher is a powerful crushing machine that effectively pulverizes materials into smaller particles. Its unique design and high-speed rotation provide efficient and uniform crushing, resulting in improved material homogeneity and increased dissolution properties. The Cage Crusher is an essential tool for various industries requiring size reduction and material processing.

Working Principle of Cage Crusher

The working principle of the cage crusher involves the following steps:

  1. Material feeding: The material to be crushed is fed into the center of the rotating cage or between the hammers. This can be done manually or through a feeding mechanism such as a conveyor belt.

  2. Impact crushing: The cage crusher consists of a cylindrical cage or housing with multiple cages or hammers arranged around a central shaft. As the cage rotates at high speed, the cages or hammers swing outward due to centrifugal force. When the material comes into contact with the cages or hammers, it is struck and shattered by the impact.

  3. Size reduction: The impact force generated by the cages or hammers breaks the material into smaller particles. The size reduction occurs through a combination of impact and attrition, where the material is repeatedly struck and crushed between the rotating cages or hammers and the inner surface of the cage or housing.

  4. Discharge: The crushed material passes through the spaces between the cages or hammers and is discharged through the openings in the bottom of the cage crusher. It can be collected in a bin or conveyed to further processing equipment.

Structure of Cage Crusher


The cage crusher consists of the following main components:

  1. Cage or Housing: A sturdy cylindrical structure that encloses the crushing chamber.

  2. Rotating Cages or Hammers: Multiple cages or hammers attached to a central shaft, arranged in a circular pattern.

  3. Central Shaft: A shaft that runs through the center of the crusher, connecting to the driving mechanism.

  4. Drive System: An electric motor, belt or chain drive, and gearbox that provide power to rotate the cages or hammers.

  5. Feed Mechanism: A system that allows the material to enter the crushing chamber, such as a feed chute or conveyor belt.

  6. Discharge Mechanism: Openings or grates at the bottom of the crusher for the crushed material to be discharged.
