Material crushing: According to the process requirements, select the appropriate mesh filter. The pre-mixed wet material is continuously poured into the crushing and mixing box from the hopper. In the crushing and mixing box, the blades on the high-speed rotating body exert impact on the material particles, and the material particles are repeatedly decomposed and mixed. The slices exert an upward force on the material. The force can prevent the materials from aggregating on the support plate, and at the same time make the materials flow in the circumferential direction due to the circumferential force of the blades, and at the same time be subjected to the axial force of the slice to flow axially, so that the material is mixed more evenly. The fully mixed material with particle diameter meeting the requirements is continuously discharged through the filter screen.

Adjusting the rotation angle of the tile-shaped paddle can adjust the force of the tile-shaped paddle on the granules. When the component force of the centrifugal force of the granules is not less than the force of the tile-shaped paddle on the granules, the granules will leave the working surface of the turntable and come out. The material is discharged from the material port to complete the granulation.

The upper cover is turned over: manually turn the handwheel to input torque to drive the worm gear reducer to work, and the power output end of the worm gear reducer drives the driving sprocket to drive the driven sprocket to rotate through the chain, driving the upper cover to rotate to the target angle with the transmission shaft as the rotating shaft , stop manually, the upper cover can be fixed at this angle. Turn the hand wheel in the opposite direction, and the upper cover can be reset.

The beneficial effects of the utility model are:

The above-mentioned split granulator can simultaneously satisfy the controllable size of the material particles to be made into granules and the controllable size of the finished granules, and carry out continuous operation of granule decomposition, full mixing and wet rolling granulation for wet materials.

Set up a filter screen, and the material that meets the volume requirements is discharged from the filter screen. The size of the mixed material particles can be controlled by adjusting the mesh number of the filter screen to adapt to different process requirements.

The blades and slices are swingingly arranged on the substrate, which can buffer the impact force on the blades and slices; the upward force exerted by the slices on the material can prevent the materials from aggregating on the support plate, and at the same time make the material move in the circumferential direction under the circumferential force of the blades. While flowing, it is also subjected to the circumferential force of the slice to flow in the circumferential direction, so that the material is mixed more evenly.

Rolling granulation can be carried out for fully mixed materials, and it is easy to adjust and control the size of the finished granules during granulation.

An air seal ring is set, and the compressed air is discharged from the air seal ring to increase the air pressure between the barrel and the turntable to overcome the gravity of the granules, and the granules will not fall under the turntable.
