Organic Fertilizer Production Line Manufacturers Tell You How to Process Cow Dung

With the rapid development of the cattle industry, fecal pollution has become a major problem. According to relevant data, in some places, the pollution of cow dung to the environment is more than 2 times, which has exceeded the total amount of industrial pollution. In fact, cow dung has many uses. In the past, it was directly fermented as the base fertilizer for crops. Now, manure can be turned into treasure and processed into organic fertilizer to obtain higher benefits. So how to process cow dung into organic fertilizer?


  1. Make 1 pack (200 grams) of cow dung compost starter with 3 kg of rice bran (straw powder, sawdust, wheat bran and rice bran are all acceptable) to make a strain mixture for later usewith compost screening machine.
  2. Sprinkle the above strain mixture evenly into 2-3 cubic meters of composted cow dung. The moisture of the whole material is kept at about 50-60%. Judging the moisture standard of the material: knead it into a ball, with watermark, no dripping, and it will disperse when you let go. , During the fermentation process, you should pay attention to shelter from the rain. If conditions permit, you can set up a canopy above the material pile, or cover it with a layer of plastic film to prevent the rain from getting wet.
  3. Be sure to turn the pile evenly and thoroughlywith the manure composting machine, and turn the low-level special materials into the middle and upper part of the pile as much as possible, so as to fully decompose. After turning the heap once, it must be turned once a week in the future, but when the temperature exceeds 70 degrees, it must be turned immediately, otherwise the beneficial microorganisms and fermentation bacteria will be killed in large quantities, which is not conducive to fermentation and decomposing.

Processing cow dung into organic fertilizer can effectively reduce the pollution caused by it, and to a certain extent, it is also of great help to production. Therefore, it is necessary to carry out organic fertilizer treatment on cow dung to play a greater role.

The Difference Between Powdery Organic Fertilizer Equipment and Granular Organic Fertilizer Equipment

As the process part of the granular organic fertilizer production equipment, the main technical means of the powdered organic fertilizer equipment are: fermentation, decomposition, crushing and mixing of organic raw materials, livestock and poultry manure or domestic garbage, sludge, distiller’s grains, biogas residue and other raw materials ,Package.

The basic process configuration of organic fertilizer equipment is dehydration, drying, fermentation, crushing, mixing, and packaging. This completes the processing of powdered organic fertilizer. Compared with the simple process of powdered fertilizers, granular organic fertilizers require further processing.

The basic process configuration of granular organic fertilizer equipment is dehydration, drying, fermentation, crushing, stirring, granulation, cooling, and packaging. Equipped with organic fertilizer granulator, organic fertilizer dryer, organic fertilizer coating machine. After the pellets are mechanically cooled, they can be packaged, stored or sold.

Organic Fertilizer Production Auxiliary Processing Equipment

Quantitative feeder

Also known as automatic feeders, silo scales, etc., the common ones are belt feeders, screw feeders, and disc feeders.

In the processing stage of organic fertilizer, it is necessary to use a forklift to mix the fermentation materials into the silo of the belt-type silo scale (feeder). The fermented product is uniformly sent to the chain mill through the feeder, and then processed step by step. In this way, there is no need to manually add raw materials to the next processing equipment through a shovel, thereby increasing the degree of automation.
