Compound Fertilizer Granulator Machine , NPK Fertilizer Making Machine

Product Introduction

The electric motor drives the pulley, and the transmission belt is transmitted through the speed reducer to a pair of two high-pressure roller bodies with a sliding mold shell to perform relative work.

The DZJ-I extruder has two rollers interacting with each other by the work of a pair of split gears.

The two rollers of the DZJ-II extruder are driven directly by two output shafts on a dedicated reducer to achieve the purpose of extrusion.

During the production, raw materials enter the hopper and are pressed and formed by the high-pressure roller body. After the mold is released, it flows to the crushing and forming part in the lower part of the roller body.

The power of crushing and forming is the relative movement of a pair of crusher rollers driven by the sprocket of the active press roller shaft via a chain drive.

After crushing and screening in the working chamber, the finished particles pass through the screen to the discharge then come out of the machine.

Working principle

The series of roller granulation is extrusion sliding model, its working principle is driven by the motor belt and pulley, through the reducer to the drive shaft, and through the open gear and passive shaft synchronization, the opposite work. The material is fed from the hopper, extruded through the roll, stripped and pelletized, and passed through a chain, transferred to the crushing sieve studio, sieved and separated from the finished product pellets, and then the feed is mixed with the new material Granulation. With the continuous rotation of the motor, the material continues to enter, in order to achieve mass production.

Mainly including compound fertilizer production equipment, organic fertilizer production line equipment, double-roll press granulat
