1. Determine the scale of the organic fertilizer production line, such as how many tons per year or how many tons per hour, and then determine the price.

2. Determine the shape of particles in the organic fertilizer production line, that is, what kind of granulator to choose: powder, column, flat ball or standard garden. Common organic fertilizer granulator equipment include: disc granulator, drum granulator, wet granulator, drum extrusion granulator, flat mold granulator and stirring gear granulator. The selection of granulator shall be determined according to the local organic fertilizer sales market. If the shape requirements of particles are different, the processing process of organic fertilizer production line is also different, and the price of organic fertilizer production line is also different.

3. Determine the configuration of the organic fertilizer production line: the equipment configuration of the organic fertilizer production line is different, the price is different, and the labor intensity is also large or small. If the output is stable and high, the general configuration is high, the automatic batching equipment, automatic packaging equipment, automatic quantitative feeding equipment, cyclone dust remover, solid-liquid separation equipment, etc. should be added to the basic equipment.

4. Determine the type of organic fertilizer production. The yield of compound organic fertilizer production line or organic fertilizer production line is the same. The organic fertilizer production line generally considers that the water content is high and the beneficial bacteria are not resistant to high temperature. The model is larger than the compound fertilizer model. There are four types of organic fertilizer: pure organic fertilizer, organic-inorganic compound fertilizer, biological organic fertilizer and compound microbial fertilizer. The configuration of organic fertilizer is also slightly different.

5. Selection of organic fertilizer fermentation turnover machine: common organic fertilizer fermentation methods include strip fermentation, tank fermentation and fermentation tank. Different fermentation methods and fermentation organic fertilizer production lines are also different. Generally speaking, the tank fermentation stacker is more suitable for the principle of aerobic fermentation (the advantages of tank fermentation: it is more in line with the principle of aerobic fermentation, it is not easy to form anaerobic bacteria, the fermentation is completely completed and the fermentation speed is fast).

6. Determine the environmental assessment to be achieved: select ordinary dust removal equipment in areas with low environmental assessment requirements, and the investment of organic fertilizer production line is low; Areas with high environmental protection requirements need to use high-performance dust removal equipment. The equipment has good effect and can fully meet the environmental protection standards required by the state. Therefore, the investment will be higher.
