As a core piece of equipment in fertilizer production, organic fertilizer dry granualtors boast a "waterless and binder-free" process as their core advantage. Their efficient and environmentally friendly forming logic makes them the preferred solution for large-scale organic fertilizer production. This equipment requires no additional water or chemical binders, relying entirely on the physical properties of the organic fertilizer raw materials and mechanical extrusion to achieve granulation. This preserves the core nutrients such as organic matter and beneficial microorganisms in the raw materials while avoiding the energy consumption of subsequent drying processes, aligning with the concept of green production.
In the actual production process, the pretreatment stage is fundamental to efficient operation. After fermentation and composting, the organic fertilizer raw materials must first be processed to a fineness of 80-100 mesh using a crushing device, and then subjected to vibrating screening to remove impurities and large particles. This ensures uniform particle size and a moisture content controlled within a suitable range of 10%-15%—a moisture content range that guarantees a certain degree of viscosity while preventing problems such as sticking to rollers and clumping during extrusion. The purified raw materials are fed uniformly into the granulator via a screw feeder. The feeding speed can be precisely adjusted according to production needs to ensure a stable material supply.
The entire process of the organic fertilizer production line features low energy consumption, low pollution, and complete nutrient retention. It is suitable for various organic fertilizer raw materials such as livestock and poultry manure, straw, and mushroom residue. By adjusting the extrusion pressure, roller groove shape, and screening specifications, it can flexibly produce organic fertilizer granules of different sizes and for different applications, providing fertilizer production enterprises with diversified solutions and helping them enhance their core competitiveness in the context of tightening environmental policies and upgrading market demands.
