Dry granulation technology
In pharmaceutical, chemical, and food industries, the need for improved powder processing methods is crucial. Traditional wet granulation often results in challenges like poor flow, inconsistent compressibility, and product integrity issues due to added moisture.
Enhance powder properties without added moisture
The dry granulation process by Alexanderwerk uses roller compaction to form granules from dry powders without liquid binders. This two-step process compresses powders between counter-rotating rollers to produce densified flakes, which are then milled into granules of uniform size and density. Alexanderwerk’s design features vertically aligned rollers and a special control logic to maintain consistent flake thickness and density, ensuring high-quality granules. This method offers versatility for both batch and continuous operations, making it ideal for applications in the pharmaceutical, chemical, and food industries. Typical uses range from tablet and capsule production to processing chemicals like silica and carbon black. Alexanderwerk’s roller compactors like the WP Pharma Series, with capacities ranging from 8 kg/h to 400 kg/h, provide tailored solutions for various industrial needs.
