Dry granulating machine for various powder materials development products. Powder raw material by the dry granulating machine without any additives can be processed into the 0.5-6mm irregular particles, so the material density is improved greatly, and reduce consumption, environmental pollution control, and reduce packaging costs, improve the operating environment of the workers.
The powdery material by dry granulation machine hopper feeder, the quantitative evenly added sheet material hopper, so that to maintain the stability of sheet material hopper feed position, and then by the sheet material inside the bucket longitudinal taper spiral of powder for precompression and arc-shaped notch is transported to the two roller; arc groove or wave trough two rolls uniformly distributed on the surface of the same shape, the meshing transmission, so that two roll uniform, reverse rotation, the material will be transported to notch bite into the groove and forced compression, compression molding pressure by the material decreases gradually, in its elasticity and gravity were used, detached from the dry granulating machine groove, into the whole grain the system is broken, and then according to the user's size requirements of sieving, grading, can meet the quality requirements of the granular products. The sieve powder back hopper recycling.
Double cone rotary vacuum dryer operation process
Open the vacuum pump, tank within a certain vacuum degree, the material tube is inserted into the powder, using vacuum material suction tank, charge amount shall not exceed the total volume of 50%, and the material is not a lump of hard. If the material density or water content is too large, should be appropriate to reduce the feed quantity. Pumping material Bi, inlet is directly communicated with atmosphere, close the valve on the vacuum line, remove the inlet nozzle, install feed pipe cap, and to ensure the sealing. Open the vacuum pipe valve, so that the tank reaches a certain vacuum degree. Open the double cone rotary vacuum dryer start button, the vessel moving around the horizontal axis.
Open the jacket heating steam (or hot water) inlet valve on the tank material, heating and drying, but in dry start stage should be continuously rotated, so as to reduce or eliminate material agglomeration phenomena.
Close double cone rotary vacuum dryer vacuum pump, open the vacuum pipe valve, open the vent valve vacuum system, so that the tank is connected to the atmosphere. |
