DEVICE DETAILS
Rotary coating machine is designed by our company’s scientific research department to solve the problem of stacking, rewetting and agglomeration of granular fertilizer. Rotary coating machine is composed of agitating tank, host machine and so on. The machine adopts a special liquid raw material or a spraying process combined with solid powder, which can form a protective film on the surface of the compound fertilizer particles and isolate it from the air, thereby effectively preventing the salt bridge and moisture absorption on the fertilizer surface. At the same time, the surface brightness of the particles is also improved, and some trace elements can be added appropriately to improve the fertilizer efficiency. It can also prolong the fertilizer effective period in the soil and effectively improve the compound fertilizer performance. The main unit adopts polypropylene lining or acid-resistant stainless steel, which is anticorrosive and durable.

WORKING PRINCIPLE
When the finished particles flow evenly into the rotating coating machine and continue to roll, first use compressed air and a spray head to spray the prepared oil-like mixed coating agent into a mist and coat it on the surface of the compound fertilizer particles. A uniform protective film is coated on the surface of the compound fertilizer particles, which effectively prevents the salting-out and moisture absorption of the fertilizer surface. This equipment is specially designed on the internal structure according to the technological requirements, and it is an effective special equipment for compound fertilizer anti-caking.
