Cow manure is the most troublesome thing for friends in the aquaculture industry, which is equivalent to the problem of dealing with agricultural straw, which is the biggest headache for us people in the agricultural industry. Collect cow dung and add crop straw in a certain proportion. After being decomposed, it can be used as raw material for Manure production, and its value will be greatly increased. Cow manure contains a lot of organic matter nutrients, and crop straw absorbs nutrients from the soil for a long time, so straw also has a certain amount of nutrients. Therefore, when these two materials are mixed to ferment Manure raw materials, they will be rich in more organic matter nutrients..jpg)
Operation steps of cattle manure straw Organic fertilizer production line:
1. Organic fertilizer dumper: collect cow dung and add straw in a certain proportion for fermentation. During the fermentation process, a composting machine is used to ferment cow manure thoroughly. Only timely and uniform composting can achieve this. After the material has fully matured and fermented, it can proceed to the next processing step.
2. Semi wet material crusher: After the above equipment has completely fermented and decomposed, the fermented and decomposed materials can be crushed using a crusher. The reason is that the newly fermented and decomposed materials are too large to be processed in the next stage, so a professional crusher is needed for processing. Here we will tell you about the commonly used types of crushers: semi wet material crushers, dual axis horizontal crushers, vertical hammer head crushers, etc.
3. Horizontal mixer: The materials processed by the crushing equipment can be transported to the horizontal mixer for mixing operations. During this period, mixing the materials evenly is a key factor, and the most important thing is which nutrients we want to add to it. During the mixing process, it is the most suitable stage.
4. Organic fertilizer granulator: the stirred materials can be transported to the granulator, thus entering the important granulation stage. I hereby recommend the disc granulator, which is a large and medium-sized granulator and is also the most commonly used equipment. In addition to this equipment, there are also wet stirring toothed granulators and roller extrusion granulators. As for which device to use, you can choose according to the customer’s needs.
5. Organic fertilizer dryer: the reason for passing through the drum dryer is that the moisture content in Manure granules is large, so it needs to be controlled within a certain range;
6. Rotary cooler: the reason for using the rotary cooler is that the processing temperature of Manure particles has reached a very high level through a series of equipment, so we need to use the rotary cooler to reduce the temperature;
7. Rolling screening machine: after being cooled, Manure particles can be screened out from Manure particles of different sizes using a drum screening machine for secondary crushing processing;
8. Organic fertilizer coating machine: the function of the coating machine is to wrap a layer of transparent coating on the surface of Manure particles, and to wrap a layer of coating without affecting the fertilizer efficiency of Manure particles so that the particles are not easy to be crushed and packed; By now, the production of Manure granules has been completed;
9. Organic fertilizer packing machine: the function of the automatic packing scale is to pack and sell the produced granules to the market.
