1.  General description
 Roller Compactor is also called Dry  Granulator. It is a new high efficient type granulating equipment that can make  powder to granules directly, and the working process does not need adding  water, stirring or drying. It is widely used in pharmaceutical, chemical and  food industry. It has a lot of advantages, so it in widely used in all kinds of  industries for treating active materials, especially suitable for  heat-sensitive drugs.
 LGS-5 is small laboratory model equipment  that used for R&D, and is favored by customers.

2.  Work principle
 The mixed powder material is charged into  the hopper by special feeding device (Pneumatic or mechanical), and then  transferred to the pressure chamber by screw conveyor. In the pressure chamber  material is compacted to high density lamina by two high pressure rollers, then  the lamina is cut into pieces by cutting system. Finally one degree milling  system will make the pieces to granules with needed size. The granulating  process is finished.

3.  Features of the equipment
 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.
