What equipment is suitable for dried organic manure granule making?
The double roller granulator also play a important role in organic fertilizer making. It can help you make powdered dried organic manure into dense, uniform fertilizer granules. It operates by pressing the organic material powder between two rotating rollers that mold the material into a pellet shape. В этом процессе, there is no water needed and organic compost can convert into pellets only by one time compressing. Поэтому, you can prepare organic fertilizer granule from dried manure quickly and with a high granulation rate.

How does the roller granulator work to turn organic and compound fertilizer pellets?
The roller granulator functions by feeding powdered organic or compound fertilizers between two counter-rotating rollers that are embossed with molds. As the material enters the rollers, it is compacted under immense pressure into a dense sheet. The pressure causes the powder particles to fuse together, creating a solid mass. This sheet is then broken into smaller, jagged pieces or directly cut into the desired pellet size, depending on the granulator design. The resulting pellets are then often rounded through additional equipment for a more uniform shape. This process does not require any liquid binder, as the pressure alone is sufficient to bind the particles together, making it an efficient and cost-effective method for producing fertilizer pellets.
