Paprastai, there are two methods of biofertilizer granulation in „Biofertilizer“ gamybos linija: dry granulation and wet granulation. The two methods have different requirements for biomaterials. Be to, different biofertilizer granulation equipment uses the two methods to make bio organic fertilizer granules.

Dry granulation requires that the moisture content of the granulation raw materials should be between 10-18%. It focuses more on squeezing the biofertilizer raw materials into granules through mechanical force, and can quickly form uniform granules. Dry granulation does not require additional drying treatment. So you can be directly package and transport the biofertilizer granules. This can reduce bio organic fertilizer production costs and energy consumption. Todėl, dry granulation has a simple process, low investment, and simple operation, which is suitable for manufacturers who open small and medium-sized biofertilizer plants.

Wet granulation is a kind of biofertilizer granulation method. It is to granulate biofertilizer raw materials with a moisture content of 30-50%. Moreover you can add certain amount of water or biological agents during the granulation process. Tačiau, in order to ensure the quality of biofertilizer granules, you also need to configure a rotary dryer and a drum cooler for the production line. Then you can package and sell the produced biofertilizer granules.

At Yushunxin, we have designed a variety of biofertilizer pelletizer. Pavyzdžiui, Disko granuliatorius ir drum granulation machine. Both of them are wet granulation, with a granulation rate as high as 93%. The granules produced are round in shape and have a diameter of 3mm-8mm. The Roller išspaudimo granuliatorius we designed adopts dry granulation process. which is suitable for granulating various common compound fertilizer materials. Granulate biofertilizer by double-roll extrusion. It can produce granules of various shapes and sizes such as semicircular and walnut shapes.
