The coating machine is a kind of equipment designed by our company to solve the problem of granular fertilizer stacking, rewetting and caking. The coating machine for compound fertilizer is composed of a mixing tank, an air compressor, a host, etc. It uses a powder powder or liquid coating process. The compound coating machine uses special liquid raw materials or a spraying process combined with solid powder, which can form a layer of protective film on the surface of fertilizer particles to isolate them from the outside air, Thus, the salt bridge effect and moisture absorption on the fertilizer surface are effectively prevented, the particle surface brightness is also improved, and some trace elements can be properly added to improve the fertilizer efficiency. It can also prolong the role of fertilizer in soil and effectively improve the use effect of compound fertilizer. Polypropylene lining is used in the host, which is anti-corrosion and durable.
Features
Compound fertilizer coating machine and supporting equipment, such as screw conveyor, mixing tank and main machine, are composed of powder powder or liquid coating process. It can effectively prevent the caking of compound fertilizer. Polypropylene lining is used in the host. According to the process requirements, the internal structure of the equipment is specially designed, which is an effective special equipment for compound fertilizer.
Working Principle
When the finished particles flow into the rotary coating machine uniformly and continuously, the prepared oily mixed coating agent is sprayed into a mist on the surface of the compound fertilizer particles with the help of compressed air and a special nozzle. The surface of the compound fertilizer granules is coated with a uniform protective film, which effectively prevents the salting out and moisture absorption of the fertilizer surface. The internal structure of the equipment is specially designed according to the process requirements, which is an effective compound fertilizer special equipment for anti caking
