Operating Principle
The machine utilizes a high-speed rotating rotor or disc to generate centrifugal force. Granules inside the chamber are continuously rolled, rubbed, and compressed against each other and the machine's inner wall. This mechanical action eliminates corners, sharp edges, and surface irregularities, producing smooth, round granules. Discharge is continuous, with adjustable retention time for optimal results.
