How to handle clumping in an organic fertilizer disc granulator?
Disc granulators are prone to problems such as clumping, uneven size, sticking to the disc, and clumps that don’t roll properly during organic fertilizer production. Timely handling can quickly restore normal granulation, ensuring the yield and appearance quality of the finished granules.
First, control the moisture content of the feed. Excessive moisture is the main cause of clumping. The moisture content of the raw material should be controlled between 25% and 35%. Excessive moisture easily leads to the formation of large clumps. Reduce the amount of sprayed water and add appropriate amounts of dry materials or powdered additives to adjust the humidity and prevent material from sticking and clumping.
Second, adjust the disc inclination angle and rotation speed of the bio disk organic fertilizer machine. If the inclination angle is too small and the rotation speed is too low, insufficient material tumbling easily leads to clumping. Appropriately increase the rotation speed and increase the inclination angle to allow the material to roll fully and granulate in layers, reducing the formation of large clumps. At the same time, ensure the inner wall of the disc is smooth and free of material protrusions to prevent material from sticking to the wall and clumping.
Control the feeding method and speed. Use continuous, uniform, small-flow feeding. Large-volume feeding at once is strictly prohibited. First, add powder, then slowly spray water, following the principle of small, frequent applications to prevent localized over-wetting and clumping. Uneven feeding will cause some material to roll excessively large while others fail to form granules, resulting in clumps of varying sizes.
Promptly clean material adhering to the discs and shafts, as clumping is often caused by material accumulation on the inner walls. Regularly clean the bottom and edges of the discs to maintain a clean inner wall; polish or install smooth liners if necessary. Immediately stop the machine and remove large clumps to prevent breakage and subsequent impact on pellet formation.
By controlling moisture, adjusting parameters, stabilizing feed, and cleaning adhering material, the clumping problem in disc granulation can be quickly resolved, improving pellet yield and granule roundness, and stabilizing production line operation.
