Working principle
Mechanical extrusion principle: The rotary
Granulator uses a set of relatively rotating grinding blades and pressing blades to force the material through a stainless steel mesh, forming particles. The relative rotation of the grinding blade and the pressing blade produces a squeezing effect, causing the material to be extruded and formed in the sieve holes.
Rotating motion principle: The material moves inside the equipment along with rotating components (such as drums or screw shafts), and through the combined effect of centrifugal force, gravity, and friction, the material rolls and flips, promoting the formation and compaction of particles.
Mold adjustment principle: The equipment adopts a screw center pressure adjustment mechanism, and the mold gap can be adjusted according to the material characteristics to ensure the pressing effect. The pressure wheel adopts multiple evenly distributed designs, which ensures smooth operation, increases the pressing area, and improves production efficiency.
Structural composition
Drum: As the core component of granulation, its material, structure, and surface treatment process have a significant impact on the granulation effect. Generally made of high-quality stainless steel, it has good corrosion resistance and wear resistance.
Blade (or ring gear): Helps materials form particles through rotation and cutting. The shape, quantity, and installation position of the blades can be flexibly adjusted according to the material properties and granulation requirements.
Drive device: provides power for the granulator to ensure its stable operation. It is usually composed of an electric motor, a reducer, a coupling, etc., and is driven to rotate the drum and blades through transmission methods such as V-belts, worm gears, and spur gears.
Control system: used to adjust equipment parameters, such as speed, feed rate, etc., to achieve precise granulation effect. PLC control system can be used, combined with touch screen operation interface, to achieve automatic control and monitoring of equipment.
Feeding device: uniformly add the material into the drum of the granulator. It is generally composed of a feeding hopper, a feeding screw, etc. By adjusting the speed of the infinitely variable speed motor, the appropriate material flow rate can be obtained.
Discharge device: discharge the produced particles from the granulator. Usually, an automatic discharge system is used to avoid particle damage caused by manual operation and improve production efficiency.
Performance characteristics
Good granulation effect: able to produce products with uniform particle size and moderate density, meeting the needs of different industries.
High production efficiency: By adopting a continuous operation mode, large-scale production can be achieved with stable particle quality and good consistency.
Wide adaptability: Suitable for a variety of materials, especially those with high viscosity. By changing the mold, particles of different shapes can also be produced to meet the compression molding needs of various materials.
Easy operation and maintenance: The whole machine is made of stainless steel, which meets various hygiene requirements and is easy to clean and maintain. The structure design of the granulator is reasonable, the components are easy to disassemble, and it is convenient for maintenance and replacement of worn parts.
High degree of automation: equipped with automatic discharge system, variable frequency speed regulation device, etc., it can achieve automatic control and monitoring of equipment, reducing operational difficulty and labor intensity.
