How to Solve the Problem of Loose Particles in Organic Fertilizer Disk Granulator Machines
The core to solving the problem of loose particles in organic fertilizer disk granulator machines is to enhance adhesion, improve density, and optimize the curing process. Specific measures are as follows:
First, optimize moisture and binder content. Control the material moisture content to 20%–30%, using atomized spraying to avoid uneven drying. Add appropriate amounts of bentonite, humic acid, or a special binder to supplement insufficient raw material viscosity, allowing the powder to effectively agglomerate and improving particle bonding strength from the source.
Next, adjust equipment operating parameters. Appropriately reduce the disc speed and fine-tune the tilt angle to extend the material’s rolling time within the disc, allowing the particles to be gradually wrapped and compacted, improving density. Maintain continuous and uniform feeding to prevent material interruption or accumulation, ensuring stable pellet formation and reducing loose fine powder.
Finally, standardize the subsequent drying process. Feed wet particles into the dryer promptly, using a stepped heating and drying method to avoid sudden cooling and heating that could cause particle cracking and loosening. Controlling the drying temperature and duration reduces the moisture content of the finished product to a safe range, allowing the granules to fully solidify and improving their hardness and shatter resistance.
Simultaneously, improving raw material compatibility involves increasing the proportion of viscous organic raw materials and reducing the proportion of inert fine powders. The raw materials are pre-mixed evenly using a twin-shaft mixer to avoid localized areas of insufficient viscosity that could affect pelletizing. Regularly cleaning the inner wall of the discs keeps them smooth and free of material accumulation and clumping, ensuring smooth material rolling and further improving granule compactness.
These combined adjustments quickly resolve the issue of loose granules, improving pelletizing rate and the quality of the finished bio organic fertilizer granultion.
