Transport the fermented and decomposed organic materials with a moisture content of about 30% -35% to the constant feeding then convey to the Cusher machine by a betl Conveyor. then enters the Sieving machine for screening, the finished material enters the computer batching system with nitrogen, phosphorus, potassium, and microIngredients such as quantitative elements and biological bacteria are added in a certain proportion, and then enter the mixer and packaging machine to produce powdered bio organic fertilizer (or directly package to produce powdered bio organic fertilizer) Or others can enter the rotary granulator (extrusion granulator) for preliminary ball forming and granulation, and the semi-finished particles are fed into the disc granulator (shaping machine) through a belt conveyor for further processing Particle shaping and re-granulation, finished particles are transported into the belt conveyor, and the second dryer is used for low-temperature and high air volume drying (exhausted gas is treated by the drying induced draft dust removal system)
