For animal manure,wheat straw and corn straw mixed farmyard manure can also be added to the raw materials of npk manufacturing process by using organic fertilizer mixer machine.After harmless treatment by using organic fertilizer machine,microbial organic fertilizer fermentation agents is added to compost and fermentation,and the organic fertilizer granulator which it is to be produced by using the organic fertilizer granulation machine is used in agricultural industries. 

In organic fertilizer production line,it is to be equipped with the fermentation 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 for sometime.And then it is to be equipped with the fertilizer mixer machine and fertilizer crusher machine to deal with the raw materials.We can use the chain crusher machine,and the horizontal mixer machine to deal with the organic raw materials.Next,when producing the organic fertilizer granulator,the fertilizer granulator machine are necessary to be equipped in the fertilizer manufacturing process.In npk fertilizer production line,we can use the rotary drum granulator machine which it is also to be equipped in organic fertilizer production line to finish the production process of the npk fertilizer granulator.The rotary drum granulator machine generally to be used by using the wet granulation method to finish the production process.This point is different from the double roller granulator machine that it is usually to use the dry granulation method to produce the fertilizer granulator.
