The equipment is one of the equipment commonly used in the fertilizer production industry. It is simple in structure, adjustable in rotational speed and dip angle, easy to repair, convenient to use and even in granularity, etc. The evenly mixed raw materials enter the disc at a constant speed. They move reciprocally up and down based on the combined action of friction of the pumping force, the centrifugal force and the materials to the required granularity, then overflow from the edge of the disc. Besides, the equipment can be widely applied to powder granulation for production technologies relating to compound fertilizers and bio-fertilizers.
