• Cement clinker crushing

4. Hammer Crusher – A Cost-Effective Solution for Soft Material Crushing

Working Principle of Hammer Crusher

A hammer crusher combines impact force and shearing force to crush materials. During operation, high-speed rotating hammers strike the material repeatedly until it reaches the target size.

In many applications, hammer crushers can achieve single-stage crushing.

Suitable Materials for Hammer Crusher

Hammer crushers are suitable for brittle and lower-hardness materials, including:

• 石灰岩
• 石炭
• 石膏
• Shale

These materials can be crushed efficiently with relatively low energy consumption.
