Organic fertilizer production line with an annual output of 10,000 to 200,000 tons
Chicken manure is a relatively high-quality organic fertilizer, and its content of pure nitrogen, phosphorus (P2O5) and potassium (K2O) is about 1.63%, 1.54%, and 0.085%. Chicken manure must be decomposed by a decomposing agent before application, and the parasites and their eggs in the chicken manure, as well as some infectious bacteria, are inactivated and deodorized through the process of decomposing. The production process of chicken manure organic fertilizer is closely related to the equipment configuration of the organic fertilizer production line. The complete set of equipment of general organic fertilizer production line is mainly composed of fermentation system, drying system, deodorization and dust removal system, crushing system, batching system, mixing system, granulation system and screening system. and finished product packaging system. The production process of chicken manure organic fertilizer generally includes: raw material selection (chicken manure, etc.) → drying and sterilization → ingredient mixing → granulation → cooling and screening → metering and sealing → finished product storage.
Performance characteristics
The production process design of chicken manure organic fertilizer includes: 1. Compound strain and its propagation technology; 2. Raw material allocation technology and biological fermentation system; 3. Special fertilizer formula technology (which can be flexibly designed and combined according to local soil and crop characteristics) 4. Reasonable secondary pollution (exhaust gas and odor) control technology; 5. Design and manufacturing technology of complete sets of process equipment for fertilizer making.
Working principle
The production process of chicken manure organic fertilizer roughly includes: raw material selection (chicken manure, etc.) → drying and sterilization → ingredient mixing → granulation → cooling and screening → metering and sealing → finished product storage.
The complex production process of chicken manure organic fertilizer is as follows: organic fertilizer raw materials (animal manure, domestic waste, dead branches, rotten leaves, biogas residue, waste bacteria, etc.) are fermented and then entered into a semi-wet material pulverizer for pulverization, and then nitrogen is added. Phosphorus, potassium and other elements (pure nitrogen, phosphorus pentoxide, potassium chloride, ammonium chloride, etc.) make the contained mineral elements meet the required standards, and then a mixer is used to mix them, and then enter the granulation mechanism to granulate, and then dry them after they come out. The products are screened by the screening machine, the qualified products are packaged, and the unqualified products are returned to the granulator for granulation.
Among them, the reasonable matching of the fineness of raw materials is very important for the production process of organic fertilizer. According to the experience of Tongda Heavy Industry, the fineness of the whole raw material should be matched as follows: 100-60 mesh raw materials account for about 30%-40%, 60-mesh to 1.00mm diameter raw materials account for about 35%, and small particles with a diameter of 1.00-2.00mm account for about 30%-40%. It accounts for 25%-30%, the higher the fineness of the material, the better the viscosity, and the higher the surface finish of the particles after granulation. However, in the production process, the use of an excessive proportion of high-fineness materials is prone to problems such as excessively large particles and irregular particles due to excessive viscosity.
