In the early stage of the
organic fertilizer production line, a composting fermentation equipment is needed to build a fermentation trough, and then the raw materials (manure, chicken manure and other farm manure, biogas residue, straw) are stacked in the fermentation trough, and the fermentation bacteria of bio organic fertilizer are mixed in the raw material pile. One kilogram of ripening agent can ferment one ton of raw materials. According to the comparison and mixing of the raw materials, the fermentation period is 10-15 days, the temperature is 0℃, and the decomposition can be completed after two days. After ripening, it is crushed by organic fertilizer crusher, and coarse material is screened out by drum screen, and then fermented. The organic fertilizer granulator machine of the utility model has the advantages of more beautiful appearance and higher granulation rate.
The fermented materials (with water content of 35%) are mixed in the mixer, dried in the dryer through the organic
fertilizer granulator machine, cooled in the cooler, screened in the screening machine, and the unqualified products are returned to the mixer. Qualified products can be passed through coating machine, silo and packaging machine.
Equipment characteristics of organic fertilizer production line
- 1. High temperature two-stage fermentation is used to recover and utilize bioenergy.
- 2. The use of organic fertilizer granulator machine can produce solid spherical particles when the moisture content is 20% ~ 40%, which greatly saves energy and equipment.
- 3. In the drying process, it has the function of polishing and mixing circle to make the particles smoother.
- 4. It can be pure organic fertilizer granulation, or organic or inorganic fertilizer granulation, without special requirements for granulation materials.
