Organic fertilizer contain a large amount of nutrients required by plants, and the supply of nutrients to plants is relatively smooth and long-lasting, and has a long aftereffect. Organic fertilizers also contain a variety of trace elements. Since all kinds of nutrients in organic fertilizers are relatively complete, and these substances are completely non-toxic, harmless and non-polluting natural substances, this provides a necessary condition for the production of high-yield, high-quality, pollution-free green food.therefore,the factory should pay much attention on the process of the production.
The organic fertilizer flat die granulator
and ring die granulator
are commonly use in the fertilizer production. They have some similarities and differences.
About the flat die granulator,there is one flat die inside,when working ,the materials will be extruded through the die,and the cutter will cut the pellet into requirement length,the diameter of the pellets also can be adjusted.the temperature rise in the production is low,so that can keep the nutrients in the raw materials,this is good to the plant.
About the ring die granulator,there are two dies inside,so it’s also called double dies granulator.this is the structure difference compared to flat die granulator.the working principle is similar with that of flat die granulator,the pellets diameter and length can be adjust too.another difference is the capacity,it’s higher than flat die kind.
The pellets from both of them are cylindrical form.some customers choose this type,but some choose round type,so the polishing machine is often used with them to make the granules in to round shape.the polishing machine also can be working with new organic fertilizer granulator besides the flat die granulator and ring die granulator. This machine can be chosen two or three level discs. After polished and the finished particles size is uniform and smooth.
