As the key equipment of organic fertilizer and compound fertilizer granulation, the double roller extrusion fertilizer pellet machine has advanced technology, reasonable design, compact structure, novel and practical, low energy consumption, and forms a small production line with corresponding equipment, which can form a certain capacity of continuous mechanized production. Zhengzhou Huaqiang Heavy Industry Co., Ltd. adopts eugenics formula, no need of drying, normal temperature production, one-time rolling forming, so that the quality of the equipment fully meets the index requirements of compound fertilizer technology. It is a special compound fertilizer with high and low concentration for growing crops and a new product for energy saving and consumption reduction in organic fertilizer industry.

The corresponding supporting facilities of roller extrusion fertilizer granulation process are: organic fertilizer compost turning, semi wet material crusher, organic fertilizer mixer, extrusion granulator, organic fertilizer roller screening machine, finished product automatic packaging machine.

The production line of organic fertilizer with double roller extrusion granulation is selected, and there is no need to configure an organic fertilizer dryer. The water content of the finished product produced by the double roller extrusion granulation machine is low, which saves a lot of cost in the investment and production of organic fertilizer. At present, this set of dry granulation fertilizer production line is the first choice for small and medium-sized fertilizer plants.
