Organic fertilizers were collected from full-scale compost factories.These factories treat organic matter from animal manure and other agricultural organic residues. These factories produce approximately 5000-150000 tons of commercial organic fertilizer per year.
In organic fertilizer production line, it is to be equipped with the fermantation compost turner machine to ferment the raw materials that the series fertilizer machine can use the simple compost turner machine to ferment the raw materials.And then it is to be equipped with the fertilizer mixer machine and fertilizer crusher machine to deal with the raw materials. Next, when producing the organic fertilizer granulator, organic fertilizer granulator machine are necessary to be equipped in the fertilizer manufacturing process. In organic fertilizer production line, we can use the double roller press machine which it is also to be equipped in organic fertilizer production line to finish the production process of the organic fertilizer granulator. The double roller granulator machine generally to be used by using the dry granulation method to finish the production process. This point is different from the rotary drum granulator machine that it is usually to use the wet granulation method to produce the fertilizer granulator.
