Chemical / mineral / fertilizer powder compacting press,Dry-process Compression and Granulating System Roller Compactor

Description

Compression and Granulating System Roller Compactor 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.

Dry roller compaction is the process of using mechanical pressure to compress fine powders into denser sheets. The basic concept of compaction is to force fine powders between two counter rotating rolls. As the volume decreases through the region of maximum pressure, the material is compressed into dense sticks or corrugated sheets. These sheets are then granulated through a milling system and series of screens to achieve the precise, uniform granule size specified.

Dry roller compaction is the best granulation process for materials sensitive to moisture and heat. Unlike wet granulation processes, which require liquid binders, alcohol solvents and high temperature drying, our roller compaction is free of these additional ingredients and energy requirements. The end result is a higher quality, consistent granule-usually at a lower cost.

2. Dry Roller Granulator Machinery 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.

HG series dry granulator has the following parts: feeding system, extruding system, front cover, water cooling system, Granulation system, hydraulic system, the body composition, cover plate, rotating screen system etc.

The whole machine is divided into machine body and operation panel, all drive parts and the affiliated facilities in the body, the work of contact with the material in operation panel, multiple sealing isolation between them, work under the completely sealed state and all parts contacting with materials are convenient disassembly cleaning, effectively prevent leakage of dust, reduced the possibility of pollution, reduced the purification area, completely accords with the GMP requirements of pharmaceutical production. We can offer FAT, SAT, IQ, OQ and PQ documents.

3. Dry Roller Granulator 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. The diagram of working principles:
