This machine is set up by rotating centrifugal disc, blower, pneumatic spray gun, wet particles made into beautiful ball pills. The wet particles made in the previous process are put into the rotating centrifugal disc, and then the rotating centrifugal disc is activated after the blower is started, so that the wet particles are subjected to the action of air buoyancy in the ring gap, rotating centrifugal force, and their own gravity, and are in the shape of a rope and strand movement in the ring, so as to form the pellets with high degree of true sphericity.
