After collecting cow dung and cow urine and mixing it with hay, rotten silage and so on, you need to make compost by crawler type compost turner.
Step 2: Crushing and mixing the ingredients
The inorganic fertilizers like N, P, K and other raw materials can be added in a certain proportion during the process of crushing and mixing.
Step 3: Granulating
In this step, there is a new type organic fertilizer granulator to granulate materials.
Step 4: Screening and recycling system
The granular material from the granulation molding system has a certain difference in pellets size. Therefore, it needs to be sieved and classified by a screener.
