Description of Roller compactor:
During granulation, the dispensed and mixed dry powder materials are fed into the upper hopper through the special feeder (pneumatic or mechanical) and conveyed to the pressure chamber through the spiral conveyor. The two high pressure extrusion wheels will press the materials into slices of high pressure density, which will be cut into small pieces by the cutting system and made into granules of desired sizes by the two-stage granule sizing system, so that the granulating process is completed.
The LG Roller Compactor is mainly composed of the following parts: material conveying system, direction changing material conveying system, extrusion system,crushing system, front cover system, water cooling system, granule sizing system, hydraulic system, machine body combination, cover plate combination and vibrating sifter (not provided for partition installation).

Features of roller compactor:
1. Material is formed by mechanical compactor, its chemical properties will not be destroyed, and effective content will not be reduced.
2. Low energy consumption and high productivity. The granulation rate can be 85% for 8~60 mesh granules.
3. Structure is simple and fastening part is less. It is convenient to install and disassembly the equipment. The disassembling time is less than 8min, and installation time is less than 8min.
4. Sealing efficiency is good and there is no leakage. So it can ensure the safety of operator and drugs.
5. When the machine is shut down, the automatic water-return function can avoid the leakage of cooling water when disassembling the equipment.
6. The surface of roller can be checker type, straight type and plain type. They can meet the requirements of treating materials with different properties.
7. The control system and main machine is in one body, and it is convenient for installation and commissioning.
8. The gap of rollers is adjustable. So the density of lamina is even.
9. There is hydraulic system, so the hardness and density of granules are adjustable.
10. Two rollers and installed up and bottom type, this structure can eliminate the effect of gravity to material. So the uniformity of material before compacting can be ensured.
