Compound fertilizer coating equipment
Compound fertilizer coating equipment is used to apply a coating material onto the surface of the granular compound fertilizer. The coating can serve various purposes such as protecting the fertilizer from moisture or humidity, reducing dust formation, and improving the release rate of nutrients. There are several types of coating equipment available for use in compound fertilizer production, including:
1.Rotary Coater: A rotary coater is a type of coating equipment that uses a rotating drum to apply a coating material onto the surface of the compound fertilizer. The fertilizer is fed into the drum and the coating material is sprayed onto the surface of the fertilizer as it rotates. The drum is heated to facilitate the adhesion of the coating material onto the fertilizer.
2.Fluid Bed Coater: A fluid bed coater is a type of coating equipment that uses a bed of hot air to fluidize the compound fertilizer and apply a coating material onto its surface. The fertilizer is fed into the bed of hot air and the coating material is sprayed onto the surface of the fertilizer. The hot air then dries the coating material, which adheres to the fertilizer.
3.Drum Coater: A drum coater is a type of coating equipment that uses a rotating drum to apply a coating material onto the surface of the compound fertilizer. The fertilizer is fed into the drum and the coating material is sprayed onto the surface of the fertilizer as it rotates. The drum is heated to facilitate the adhesion of the coating material onto the fertilizer.
4.Disc Coater: A disc coater is a type of coating equipment that uses a rotating disc to apply a coating material onto the surface of the compound fertilizer. The fertilizer is fed onto the disc and the coating material is sprayed onto the surface of the fertilizer as it rotates. The disc is heated to facilitate the adhesion of the coating material onto the fertilizer.
5.Spray Coater: A spray coater is a type of coating equipment that uses a spray gun to apply a coating material onto the surface of the compound fertilizer. The fertilizer is fed into a hopper and the coating material is sprayed onto the surface of the fertilizer as it passes through the spray gun.
When choosing the type of coating equipment for compound fertilizer production, it is important to consider factors such as the type of coating material, the desired thickness of the coating, the production capacity of the production line, and the desired quality of the final product.
