There are two types of vibration sources for a flowing vibration: one is driven by a vibrating motor, and the other is caused by a vibration of a normal motor through a vibrating box, which makes a spring. When vibrating, the bed size, the latter is better. Fluidized bed spray granulation dryer, fluidized technology, atomized technology and drying organic combination of three. It is the seed that carries the atomized spray liquid into the fluidized bed, so the seed continues to grow and dry to reach the required size, time out of the catapult. The device has small and large production capacity and can create large particles. The equipment has been increasingly used in industry.
