Dry granulator and contact all material part adopts 304 stainless steel material, pressing wheel except. Press wheel with duplex stainless steel 0Cr26Ni5Mo2, surface ion nitriding treatment, this kind of material is called 329J.
Dry granulating machine comprises a feeding mechanism, pressing mechanism, a hydraulic mechanism, a frame and electric control components.
1, the feeding component
A motor reducer, screw, funnel unequal pitch composition, degassing, the material pre pressure, forced into the pressing parts.
2, pressed parts
Composed of a motor, reducer, shaft, bearing, roller etc.. Used roller pressure, wear resistant, acid and alkali resistance, corrosion resistance, high strength stainless steel and through special heat treatment and (solid solution treatment and surface ion nitriding). Sheet material after pressing wheel after extrusion with certain strength, thickness.
The 3 part, granulation
Dry granulator granulation unit consists of a motor, reducer, frequency converter, a granulating mechanism and mesh, the sheet material pressing parts out, after two times of granulating to obtain the required particle, the granulation adopts blade, the granulation adopts rotation cage type, particle size is controlled by the mesh mesh. The screen can be matched (phi 1.0mm, Phi 1.2mm, Phi 1.5mm, Phi 2.0mm)
4, hydraulic components
Dry granulating machine hydraulic component is composed of a pressure device: electric hydraulic station, two cylinder, high pressure oil pipe, valve, pressure gauge. After tabletting forming products required hardness is controlled by the pump pressure and feeding speed and wheel speed to.
5, electrical control components
Electrical 220V two-phase power supply, inverter /PLC/ touch screen and other electrical components and circuit, the feeding, tablet, granule for the stepless speed regulation to control. |
