For the production of compound fertilizers, a double roller granulator is essential. What equipment is needed in addition to the double roller granulator to produce compound fertilizers?
Compound fertilizer granulation press granulator, what supporting equipment is needed for compound fertilizer granulator? Roll extrusion granulator is the main equipment for compound fertilizer granulation of powder materials. In addition to the roller extrusion granulator, the entire npk fertilizer production line also needs automatic batching machines, mixers, vertical pulverizers, drum screening machines, dryers, coolers, secondary drum screening machines, and automatic packaging scales. Belt conveyor connection.

The principle of the double-roll extrusion granulator: The double roller granulator adopts two rollers, leaving a certain gap (adjustable) between each other, and the two reverse at the same speed. There are many arc grooves of the same shape and size on the surface of the roll. According to the difference of the target compression ratio of the material, the trough of the arc groove of one roll is selected to be aligned with the trough of the other roll. The two rollers are horizontally parallel, and the powdery material is continuously fed from the top of the two rollers, evenly relying on self-weight and forced feeding between the two rollers. When the material enters the bite, it is gradually bitten by the roller. With the continuous rotation of the roll, the space occupied by the material is gradually reduced and compressed.
