Product Details
Principle
Materials are forced into the gap between two counter-rotating rollers by a pre-compression screw. Under constant ultra-high pressure from hydraulic cylinders, materials are intensely compressed in the ball sockets, undergoing physical displacement and deformation to form solid briquettes.

Frequently Asked Questions
- Q: Is a binder always necessary?A: Depends on the material. Some allow dry formation; others require small amounts (e.g., starch, bentonite) for strength.
- Q2: Can shapes be customized?A: Yes. Common shapes include pillow, oval, and square. Socket size and depth are fully customizable.
- Q3: How to replace worn rollers?A: We use easy-to-replace sleeves, so there is no need to dismantle the main shaft, minimizing downtime.
