Coarse Crusher
Coarse crusher that breaks lumpy and granular materials into coarse particles as a pre-crushing step before fine grinding.
Overview
The CSJ coarse crusher breaks lumpy and granular materials into coarse particles, serving as a pre-crushing stage ahead of fine grinding. A rotor with blades shears the feed against fixed knives, and a screen sets the output size.
Features
- Handles hard, tough and fibrous lumps
- Coarse output suited to pre-crushing before fine milling
- Robust rotor and replaceable knives
- Output size adjustable by changing the screen
- Easy to maintain
Working Principle
Rotating blades shear and impact the feed against fixed knives inside the crushing chamber. Crushed material that is small enough passes the screen to the outlet, while oversized pieces are retained for further crushing.
