The organic fertilizer granulation equipment drum granulator is a molding machine that can manufacture materials into specific shapes. The cylinder is lined with special rubber plates or acid resistant stainless steel plates, achieving automatic scar removal and tumor removal, eliminating traditional devices. A drum type granulator, in which steam, gas ammonia, or phosphoric acid or nitrogen solution, phosphorus ammonia slurry, and heavy calcium slurry are introduced to complete the chemical reaction and heating process of compound fertilizer granulation in the cylinder; Alternatively, in the cold granulation process of adding a small amount of water to the compound fertilizer, the materials that need to be granulated are rotated through the cylinder, causing rolling rotation when there is no material in the cylinder, and then agglomerated into balls at a certain humidity and temperature to complete the granulation process.

The working principle of the organic fertilizer drum granulator: The rotating components of the traditional horizontal centrifuge are separated into two parts: the inner and outer shaft systems that rotate synchronously. The outer shaft system is fixed axially, and the inner shaft system can move axially under the action of the synchronous rotating oil cylinder. The filter cloth is bag shaped, with one end fixed to the large end of the drum on the outer axis and the other end fixed to the small end of the push plate on the inner axis. During separation, under the action of centrifugal force, the filtrate passes through the filter cloth and drum, and the solid is intercepted by the filter cloth and forms a filter cake; When unloading, under the action of synchronous rotating oil cylinder, the inner shaft system is pushed out along the axial direction and drives the filter bag to flip, while completing the operation of filter cake unloading and filter cloth regeneration.

The granulation process of organic fertilizer granulation equipment is: the main motor drives the belt and pulley, which are transmitted to the driving shaft through a reducer. The split gear installed on the driving shaft engages with the large gear ring fixed on the body, working in opposite directions. The material is added from the feeding end and passes through the inside of the cylinder. Through the special structure inside the cylinder, it is made into particles and flows out through the discharge port. Due to the continuous entry of materials and the continuous rotation of the granulator, mass production can be achieved.
