Compound Fertilizer Disc Granulation Process Introduction

1. Transport qualified raw materials such as nitrogen, phosphorus, potassium and filling materials to each relevant weighing equipment.
2. After weighing, the raw materials are transported to the mixer for strong mixing.
3. Transported to the material equalizer, evenly added to the rotating disc of the disc granulator; liquid components or the appropriate amount of water through the liquid component distributor of the disc granulator dripping on the material in the disc to meet the amount of liquid phase required to form a ball, the rotating disc and disc edge friction and centrifugal effect on the material to produce circumferential motion, so that the powder particles rub and squeeze each other, and gradually agglomerate into a ball, due to The gravity and centrifugal effect of the particles are different due to the difference in quality, when the gravity and centrifugal effect increases enough to overcome the friction between the particles will be thrown out of the disc, the smaller particles remain in the disc to continue to agglomerate fine powder particles.
4. Conveyed to the rotary dryer for heat exchange with the heat from the hot air furnace.
5. Conveyed to the rotary cooler, where the fertilizer is cooled by natural cold air or forced cold air.
6. Conveyed to the sieving machine, after screening, the fine particles are directly returned to the material equalizer, and the large particles are crushed by the pulverizer and then returned to the material equalizer.
7. After screening, the qualified products are conveyed to the wrapping machine for film coating.
8. Conveyed to automatic packing scale for weighing, packing and storage.
9. Drying, cooling and workshop dust are discharged through cyclone dust collector, labyrinth dust chamber and wet scrubber after three-stage treatment.
