Cow dung and accessories are mixed together to form a moisture content of 50-60%, which is kneaded by hand and printed with water between fingers but not discharged. When the stacking height is 0.8m-1.5m and the ambient temperature is below 15 ℃, cover with film or straw curtain. When the internal temperature rises to 25 ℃, the covering is uncovered. Generally, in the fermentation of 2 to 3 days, the organic fertilizer machine turns over the material and then ferments. The purpose of doing this is to make it fully ferment and kill pathogens and eggs. The purpose of turning once is to let a large amount of air enter into it and make it heat again and ferment again. In general, the fermentation is complete in seven days. Next, we can make granular organic fertilizer..jpg)
1. In the period of cow dung fermentation, the material was crushed by a crusher, so that the particle size requirements after crushing could meet the requirements of later organic fertilizer granulator production.
2. Use forklift truck to put manure organic fertilizer into the mixing mixer. Before mixing and mixing, according to the formula, add n, P, K and other trace elements into the mixing mixer to start mixing.
3. The mixed materials are transported to the organic fertilizer granulator, and the granulated materials are sent to the cooler after drying. The materials are sieved at room temperature. The particles that meet the requirements enter the coating machine and are packaged after coating. The particles that do not meet the requirements return to the granulation system and continue granulation.
4. The final qualified granules are packed automatically.
Note: the production of cow manure organic fertilizer can be made into powder or granular form. The organic fertilizer manufacturers need to choose the production mode according to their actual situation, and expand the investment scale when the opportunity is ripe in the future.
