Introduction to the working principle and equipment of roller granulator

I. INTRODUCTION of roller granulator

Roller granulator is a molding equipment that makes materials containing certain moisture into a specific shape. It is mainly composed of rack, fixed roller device, movable roller device, transmission device, etc. Its working process is to extrude and form the materials entering the roller granulator at one time. The machine has the advantages of reasonable structure, stable and reliable performance, convenient cleaning and maintenance, low energy consumption, long service life, high granulation rate, etc.

II. Working principle of roller granulator

The working principle of the double-roller granulator is that the motor uses the belt to drive the reducer, and then the reducer drives the fixed roller and the movable roller to rotate synchronously through chain drive. The material falls between the double-roller from above the equipment, passes through double-roller extrusion and granulation, and is discharged from the outlet. The first function of extrusion is to squeeze out the air between particles, and the other is to make the distance between particles close enough to generate attraction such as Fan Dehua force, adsorption force, Crystal Bridge and embedded connection. Extrusion granulation particles are mainly formed by the force between molecules.

III. Structural characteristics of roller granulator

(1) the integrated welding and processing rack ensures the processing and matching accuracy and form and position tolerance of each part, and effectively improves the installation accuracy and reliability of the whole machine.

(2) belt transmission 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, thus obtaining products that meet the requirements.

(4) the split structure of the roller and the wheel hub is convenient to replace the roller.

IV. Advantages of roller granulator

(1) due to the extrusion molding of raw materials in the granulation process, the initial strength of the product is relatively high.

(2) the product granularity is uniform.

(3) low equipment investment and small floor space.
