The machine uses dry granulation to directly form the powder into granular products without additives and intermediates. After granulation, the particle size is uniform, the bulk density is high, the fluidity is good, and it is not easy to form layers, which not only reduces the waste of powder, but also prevents environmental pollution. Easy to store and transport, control solubility porosity and specific surface area.
Feeding System
Raw materials of dry granulator can be fed by hand, elevator or vacuum feeder. During automatic feeding, the material level sensor monitors the material level in the hopper in real time and automatically adjusts the feeding speed. The powder is scattered in the hopper and quantitatively transported to the feeding port of the pressure wheel through the horizontal feeding screw.
Roller Extruding System
The powder is pressed into sheets by a pressing wheel, and the gap between the pressing wheels is accurately adjustable to meet the requirements of different sheet thicknesses. According to the powder properties, smooth wheel, reticulate wheel and straight wheel can be selected to meet the forming requirements. After being pressed into tablets and pre-crushed, the tablets enter a granulation mechnism.
Mill System
According to the requirements of grain collection, the whole grain net with different apertures can be selected, and the gap between the whole grain wheel and the whole grain net can be adjusted. According to the property of the material, spiral or hob grading wheels can be selected. The whole mesh can also be equipped with woven mesh or punched mesh plate.
Discharging System
An aggregate port and a discharge port are arranged. The aggregate port collects a small amount of uncompressed raw materials in the triangle area. The discharge port is equipped with a vacuum discharge assembly with a respirator to facilitate vacuum delivery to the screener.
Product Features
The whole machine is designed into two major parts such as machine body inside part and the work part outside the operation panel. All driving parts and auxiliary facilities are designed inside the machine. The work part that contact material is set outside the operation panel. The middle part is isolated by multiple sealing. The work part works under a fully closed status, and al parts that contact materials are convenient to assemble, disassemble and clean, so as to effectively avoid dust leakage, lower pollution possibilities and reduce cleaning area, fully meeting GMP requirements for medicine production.
3.1. functions in one unit, These are compression, crushing and milling.
3.2. Simplified process to obtain highly stable granules. No water or other liquid is added and no need drying, so the loss of active ingredients due to decomposition can be eliminated.
3.3. Pressure rollers with a water cooling system;
3.4. Overall modular design, compact structure, better space utilization;
3.5. The power area is separated from the work area to prevent cross contamination;
3.6. Horizontal feeding structure, exposed installation of extrusion system, easy to clean and maintain;
3.7. Meet GMP requirements
