1. Adopting the combination structure of bachelor and one side of roller with holes solves the problem that the sludge contains too much water and the granulating and bonding problem.

2. High production efficiency, with a ball-forming rate of over 90%;

3. The discharge is uniform, and the size of the sludge particles squeezed by the roller granulator is uniform, which can meet the requirements of the lower-end process on the size and shape of the sludge;

4. The overall operation of the equipment is stable and the noise is low. At the same time, the sealing cover is adopted to receive materials. The work site is clean and tidy, and the operation is convenient.
