Rounding & Shaping Machine for Compound/Organic/BB Fertilizer Granules
Product Overview
The Polishing & Rounding Machine is specifically designed for shaping and rounding fertilizer granules after the granulation process. It effectively eliminates sharp edges, irregular shapes, and rough surfaces, producing uniform spherical granules with smooth appearance. This machine is widely used in compound fertilizer, organic fertilizer, and BB fertilizer production lines.

Working Principle
Granules enter the machine and are driven by a high-speed rotating disc or rotor. Through centrifugal force and friction, the granules collide, roll, and polish against each other and the machine wall, gradually forming smooth, round particles. Qualified granules are discharged, while unqualified ones are returned for re-processing.
