The experimental dry granulation machine is suitable for laboratories, intermediate experimental devices, and small-scale production. The particle size can be adjusted to meet different requirements, with high yield, high degree of automation, convenient use, and good universality. Water cooling devices can be added at the pressure wheel according to customer needs.
The structure of the experimental dry granulation machine mainly has the following characteristics:
1. The lifting part is achieved by hydraulic lifting cylinders to raise and lower the feeding mechanism, controlled by limit switches, and interlocked with feeding, pressing, and whole granule.
2. The whole granulation part is driven by a variable frequency speed regulating motor to rotate the granulation blade, shaping the sheet material into the required particles and discharging them in the mesh.
3. The feeding part is driven by an electric motor to pre press and degas the powder using a double cone screw with unequal pitch. According to the performance of different materials, the feeding speed can be infinitely adjusted (variable frequency speed regulation).
4. Cooling can be achieved by using tap water or cooling water, which is forcibly cooled on the surface of the pressure wheel through the HS-X32A bidirectional inner tube rotary joint via the shaft hole.
5. The tablet press is driven by an electric motor to drive a cycloidal pinwheel reducer, which rotates the transmission shaft and drives the relative rotation of the two pressure wheels to work together with pressure, compressing the powder into flakes. According to the compressibility of different materials, the speed of the pressure roller can be infinitely adjusted (variable frequency speed regulation)
6. The pressure section is supplied with oil to the oil cylinder by an electric vane pump, which is stabilized by an accumulator. The upper and lower pressure limits are set using an electric contact pressure gauge.
