The process flow of organic fertilizer production line: raw material treatment → harmless treatment → mixed ingredients → granulation → cooling screening → metering sealing → finished products warehousing. When choosing to purchase organic fertilizer equipment, we should first consider the needs of our own factories. After market research, we should determine the required scale of fertilizer production, and determine the appropriate scale of production based on market prospects and raw material supply. Then understand the organic fertilizer equipment for matching selection.

1. Determine the output size of complete sets of organic fertilizer equipment: for example, the annual output of tons, or exactly to the number of tons per hour, some factories can run 24 hours, while others can only run 8 hours, so it is necessary to specify the output per hour, and matching equipment is more reasonable.

2. Determine the shape of the grain: powdery, columnar, oblate or standard round. Commonly used granulators are: disk granulator, mixing granulator, roll extrusion granulator, flat mold granulator, ring film granulator. The selection of granulator should be based on the local fertilizer sales market, different equipment, the price is different.

3. The distribution level determines the cost of organic fertilizer equipment. Determine the configuration of equipment: the level of configuration is different, the price of equipment is different, the amount of labor is different.

4. Determine the type of fertilizer production. General organic fertilizer types are divided into four types, pure organic fertilizer, organic or inorganic compound fertilizer, biological organic fertilizer, compound microbial fertilizer, different varieties of equipment are also different.

5. Determine the main types of organic raw materials: common organic raw materials include chicken manure, pig manure, cow manure, sheep manure, straw, pharmaceutical residue, furfural residue, humic acid, pool mud, municipal sewage treatment plant sludge, etc. The choice of different raw materials and equipment is also slightly different.
