Dry granulating machine feeding structure to the decisive role of dry sheet forming effect of drugs on. The feeding system generally adopts special unequal screw feeding, feeding screw rod can give certain pressure in the feeding process, to ensure that such a pressing material hardness and thickness, the drug sheet pressure out of reach the requirement. All kinds of powder materials from the top into dry granulation, degassing, screw preloading on roll, in the roll extrusion pressure under the action of the huge causes the material to produce plastic deformation and pressed into sheet. The sheet material after crushing, whole grain, screening process, get granular products. The extrusion pressure size according to the need of pelletizing operation by hydraulic cylinder pressure regulator.
The key of dry granulator granulation system is rolled alloy sheet formed by crushing, granulating, demanding uniform particles and high rate of finished products of grain, dry granulating machine using the first sheet material crushing, then granulating structure of drum rotary rolling to the screen. Can greatly improve the production efficiency.
Dry granulating machine application:
Capsule filling particles, paint, detergent, catalyst, strontium carbonate, white carbon black, chemical fertilizer, inorganic salts, chloroisocyanuric acid, bleaching powder, pesticide, oxides, and industrial dust recycling materials: such as iron, lead, zinc plant dust, aluminum dust, converter dust, dust, grinding dust.
The main advantage of dry granulator:
1 material by dry granulator pressure forced compression molding, do not add any wetting agent, the purity of the product is guaranteed.
2 dry granulator short technological process, low energy consumption, high output.
3 dry granulation, without further drying process, more conducive to the existing production process of the connection and transformation.
4 high granule strength, bulk density increased compared with other method of granulation is more significant. Especially suitable for increasing the mass density of product.
5 big operating flexibility, adapt to a wide range of extrusion pressure, the size can be adjusted by hydraulic pressure. |
