The composting stacker is used for cow dung organic fertilizer fermentation, and the equipment ensures sufficient nutrition of base fertilizer


In order to ensure that the base fertilizer can adequately supply the nutrition for the growth of vegetables in the whole growth period, the method of mixing organic fertilizer with chemical fertilizer is often adopted in the base fertilizer. Generally, 100% of the required phosphorus fertilizer, 20% - 50% of potassium fertilizer and 30% - 50% of nitrogen fertilizer are mixed into organic fertilizer and applied together. The amount of chemical fertilizer should be adjusted according to the quality and quantity of organic fertilizer. On the one hand, adding biological bacterial fertilizer to the base fertilizer can better improve the soil and improve the absorption and utilization rate of nutrients; On the other hand, biological bacterial fertilizer can prevent root diseases and the harm of continuous cropping by bacteriostasis.

Cow dung fermentation was carried out by composting stacker, and microbial strains were added to promote the process of cow dung fermentation. Cow dung and bacteria are evenly stirred and stacked in the built fermentation tank. When the material rises to a certain temperature, pour it with a dumpling machine to reduce the temperature and facilitate strain propagation. Crawler stacker can also be used for fermentation. Compared with tank fermentation, it does not need special tank body and is more convenient to use.

After the fermentation materials of the small cow dung organic fertilizer production line are batched by the batching system, they are lifted and transported by the belt conveyor, crushed, screened and graded. The materials on the screen are returned to the mixing room for batching. The powdery part under the screen is transported by the belt conveyor for batching, granulation, drying, cooling, coating and packaging. The finished products are stored in the finished product warehouse.
