1. Unique wheel convey, to reduce friction, super low failure rate.

2. No damage to the fiber and impurities.

3. Fewer matching sets save the cost of maintenance.

4. The only consumption of power lies in the rotation drum, which is half to one third of the hydraulic pulper. It saves much power than the traditional gear drive.

5. Combine pulping, roughing with deslagging, greatly save the cost.

6. Pulping density: 14~18%

7. Consistency of outflow pulp: 3~4%
