Only after the cow dung has been completely fermented and decomposed can it be used as organic fertilizer and applied to the fields and crops. A small amount of cow manure or organic manure from your own household can be artificially used with traditional composting and fermentation.
If it is an organic fertilizer production plant that requires a large amount of cow dung for processing, 10 tons, 20 tons of cow dung, such a quantity needs to use organic fertilizer fermentation equipment to carry out the fermentation process. There are many kinds of equipments required for biofertilizer production. Which fermentation equipment can be selected for fermentation processing of cow dung? What are used? Let's take a look.
Before the cow dung is fermented, it needs a simple treatment:
The simple treatment of cow dung is to prepare for subsequent fermentation. The cow dung is added with a starter, and then straw, wheat bran and other auxiliary materials are added to adjust the water content. Make the water content in the cow dung reach about 60%, and put it into the mixing equipment for uniform mixing.
After the cow dung has been pretreated, the subsequent organic fertilizer processing technology will begin. Cow dung is made into organic fertilizer. The organic fertilizer manufacturing equipment used includes:
1. Trough type stacker
The tank type biological fermentation is adopted, and the stacker is used to shift the other end of the fermentation tank by three meters, and at the same time, it can achieve the purpose of water regulation and uniform mixing, which can save a lot of land and a lot of labor. It can achieve the purpose of being fully decomposed.
Use a shovel to move and transport the fermented organic fertilizer at the top of the fermentation pile or the fermentation tank to the semi-finished product stacking area, which helps to ensure the automation of the entire production line and reduce labor costs.
3. Screening machine and semi-wet material shredder
Use a sieving machine to sift out the large debris and stones in the organic fertilizer, and then crush the large materials with a semi-wet material pulverizer, which is not only beautiful but also convenient for subsequent processing of powdered organic fertilizer or granular organic fertilizer.
4. Horizontal mixer
The sieved and crushed organic fertilizer and the addition of N, P, K and other elements are thoroughly mixed and stirred to ensure the stability of the product quality and at the same time increase the nutrition of the cow dung organic fertilizer.
