Equipment flow of NPK fertilizer granulator production line
The production line process of NPK fertilizer granulator includes raw material batching machine, fertilizer mixer machine, crusher, NPK fertilizer granulator, particle dryer, particle cooler, coating machine for finished product, and quantitative packaging machine for finished product.
Working principle of NPK fertilizer granulator:
The belt and pulley are driven by the main motor and transmitted to the driving shaft through the reducer. The split gear installed on the driving shaft and the large gear ring fixed on the machine body engage and work in opposite directions. The materials are added from the feeding end, and then made into particles through the inner part of the cylinder and the special structure inside the cylinder. Later, the particles flow out through the outlet, The continuous rotation of granulator can realize mass production.
NPK fertilizer granulator is filled with steam, gas ammonia or phosphoric acid or nitrogen solution, phosphorus ammonia slurry and heavy calcium slurry to complete the granulation process of chemical reaction and heat supply in the cylinder; Or cold granulation process of compound fertilizer with a small amount of water. Through the rotary motion of the cylinder, the material to be granulated will roll and rotate when there is no material in the cylinder. Under certain humidity and temperature, the material will agglomerate into a ball to complete the ball making process.
