Description

Dry granulator can make the powder raw material directly to granular products to meet user requirements without any intermediates and additives. after granulating Product granularity uniformity and bulk density increased significantly which not only control the pollution but also reduce the production cost and improve the appearance and liquidity material to facilitate drug next operation process and storage. Also can control the solubility, porosity, specific surface area and many other advantages. Because particles compression time is short, long time no heating process, so that the active ingredients of drugs is not easy to be destroyed, especially suitable for wet and heat sensitive drugs.

Working process

Put dry powder material to hopper by hand or automatic feeder (pneumatic or motor), then transport them to pressure chamber by screw. Push back the material into high density slice by two high pressure extrusion wheels and make the particles based on customer requirement then granulating finished.

working principle

The granulation process of the machine is to press powder material to blocky shapes by a pair of press rollers that moves in opposite directions so as to improve its proportion. And then it is shattered through the secondary granulating mechanism to finally become the qualified material. Besides, it guarantees that the material is clean and it produces no pollution in the granulating process.
