The production of small-scale automatic compound fertilizer equipment mostly uses drum granulators, disc granulators, roller extrusion granulators, etc., which have high investment, high cost, and low output.
The small-scale compound fertilizer production line equipment includes: chain crusher → disc mixer → roller extrusion granulator → drum screening machine → automatic packaging machine. The small-scale compound fertilizer production line requires two steps to process commercial organic fertilizer: the preliminary fermentation and treatment part and the deep processing granulator part.
The small-scale compound fertilizer production line equipment mainly includes two parts: fermentation and production. Due to the presence of harmful substances in fresh pig manure and its inability to become a commodity in its form. The purpose of fermenting pig manure is to treat it harmless and make it a fertilizer with high organic matter content. The fermented pig manure is loose and odorless, and can be processed into powder or granular organic fertilizer as needed, and then packaged and sold using an automatic packaging machine. This is the organic fertilizer production part.
The small-scale automatic production line for compound fertilizer has low investment, fast efficiency, and good economic benefits. The complete equipment process layout is compact, scientific and reasonable, and technologically advanced. Energy saving and consumption reduction, no discharge of three wastes, stable operation, reliable operation and convenient maintenance. Wide adaptability of raw materials, suitable for granulation of various raw materials such as compound fertilizers, pharmaceuticals, chemicals, feed, etc., with high product granulation rate. It can produce various concentrations and types of compound fertilizers (including organic fertilizers, inorganic fertilizers, biological fertilizers, magnetized fertilizers, etc.).
The machine process flow of the small-scale compound fertilizer production line can be divided into: raw material batching, raw material mixing, raw material granulation, particle drying, particle grading, particle cooling, finished product coating, and finished product packaging.
