Coating drum for coating granules in fertilizer production

Rotary drum coater can improve the storage and usability of fertilizers. By applying a protective layer to granules, it effectively prevents caking and ensures a longer shelf life. Designed to function similarly to granulators, it handles the coating process efficiently to guarantee consistent and high-quality results across the production line.

Working Principle

The rotary coater is divided into two sections. In the first section, granules are sprayed with oil to create an initial coating. After passing a separating baffle, the granules move into the second section, where powder is applied to complete the coating process. This method ensures an even, thorough coating on each granule.
