Organic fertilizer equipment (new type organic fertilizer granulator) double roller press granulator



The roller pelletizing machine is a kind of molding equipment that makes the material containing certain moisture into a specific shape, which is mainly composed of a frame, a fixed roll device, an active roll device, a transmission device, etc. The working process is that the material entering the counterroll granulator is extruded and formed at one time. The machine has the advantages of reasonable structure, stable and reliable performance, convenient cleaning and maintenance, low energy consumption, long life and high granulation rate. Rotary drum granulator also has the same advantages.



Working principle:

The working principle of the roller granulator is that the motor uses the belt to drive the reducer, the reducer then drives the fixed roller and the active roller to rotate synchronously through the chain drive, and the material falls from the top of the equipment between the rollers, through the double roller extrusion, granulation, and discharge from the discharge port. The effect of extrusion is to push out the air between the particles, and to make the particles close enough to produce attractive forces such as van der Waals forces, adsorption forces, crystal Bridges, and embedded connections. The particle strength of extruded granulation is mainly formed by the force between molecules.

Structural characteristics:

(1) The integrated welding and processing frame ensures the processing, matching accuracy and form and position tolerance of each part, and effectively improves the installation accuracy and reliability of the whole machine.
(2) The belt drive is adopted between the motor and the reducer, which is stable and reliable, and has overload protection function for the motor
(3) The movable roller device can adjust the pre-pressure of the movable roller device by adjusting the position of the bearing seat, so as to obtain products that meet the requirements.
(4) Split structure of drum and hub, easy to replace the drum.

Advantages and characteristics:

(1) Because the raw material is extruded during the granulation process, the initial strength of the product is high.
(2) The product size is uniform.
(3) Low equipment investment, small footprint.
