Dry granulation is one of the most new granulation method developed following the second generation of granulation method "one-step granulation" after. It is an environmental protection type granulating process, energy saving and no pollution, no wetting agent, environmental problems without solvent granulation explosion-proof and exhaust emission pollution; dry granulator obviates the drying process, saving a lot of energy; with the new adhesive dry granulation required continuously developed, dry granulation cost sharply.
Dry granulating machine comprises a feeding mechanism, pressing mechanism, a hydraulic mechanism, a frame and electrical control components.
1, dry granulator feeding component is composed of a motor speed reducer, the conical screw, funnel unequal pitch, degassing, the material preloading, forced into the pressing parts.
2, dry granulator is composed of motor, reducer pressing parts, shaft, bearing, roller etc.. Used roller pressure, wear resistance, acid and alkali resistance, corrosion resistance, high strength stainless steel and through special heat treatment and (solid solution treatment and surface nitriding treatment). Sheet material after pressing wheel after extrusion with certain strength, thickness.
3, 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 made in required size, the granulation with blade, the following granulation adopts cage type, particle size of a mesh mesh to control. The screen can be matched (phi 1.0mm, Phi 1.2mm, Phi 1.5mm, Phi 2.0mm)
4, 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.
5, dry granulating machine electric control parts
Electrical 220V two-phase power, by the inverter /PLC/ touch screen and other electrical components and circuit, the feeding, pressing, granulating stepless speed control. |
