Organic Pig Manure Is the Best Natural Fertilizer(two)

 Add proportional probiotics, rice hull and humic acid uniformly, then adding rice bran (or wheat bran, corn meal and so on) for mixing, evenly spreading on fermentation raw materials, and then stirring equably for pile composting, We mix the formula of organic and inorganic materials according to different series of products and mix them fully in blender, it's best to use a professional equipment  -horizontal mixer that whips together quickly and evenly. About fermentation time and temperature, it takes about a week to complete the composting and fermentation. optimum environmental temperature for fermentation is 25 to 35 ℃. Adopt the hydraulic type groove turning machine, generally fermentation completion criteria: the smell of fermented compost with odor but not smelly.
 The compost lump materials should be grinded before the granulating process by the cage crusher, and after it needs horizontal mixer to mix fully the crushed materials for better granulation. It is not easy to stick to the material and wear resistance. The colloidal-pin wheel reducer has the characteristics of compact structure, convenient operation, uniform mixing, and convenient discharge and transportation

Granulating process is the core part in this production line, so we choose the suitable model of fertilizer granulator according to customer’s detailed requirements. Disc granulator machine can be chosen to granulate the materials evenly. 
In the production process of biological fertilizer, not only the water content of the particles generally exceeds the indicators after forming, requiring low temperature drying, but the moisture content of organic materials is about 30% ~ 40% after fermentation, and the moisture content of the particles after granulation is generally between 15% ~ 20%, which needs drying treatment with rotary dryer, because the fertilizer quality index of moisture content requires less than 14%, Therefore, the drying process is an indispensable and important process in the process of biological fertilizer production, which directly affects the output, quality and energy consumption. It is very important to choose the type and specification of the dryer reasonably and control the process conditions.
Drying materials are transported by belt conveyor and feeding into the rotary cooler, the cooling process mainly involves the use of wind fans to feed natural air into the cooler through pipelines to cool the materials. The wind direction in the cooling machine is reverse flow. The exhaust gas pumped into the settling chamber by the fan and pipe is treated and discharged into the atmosphere as the drying exhaust gas
Materials were screened after cooling, and the large particles of materials are crushed were transported into granulator with the sifted powder by the return belt for re-granulation, and the finished products enter the automatic packaging system for packaging.
