Our colleagues Albin “Al” Friedrich and Matt Walczer, both National Sales Managers at Alexanderwerk Inc. (USA), recently wrote an article about how a roller compactor can be configured to properly and consistently provide a homogeneous powder blend during the granulation process. Additionally, the article covered in more detail how internal tests conducted on a WP 200 Pharma at Alexanderwerk in Montgomeryville (USA) were used to help recycle fines screened out during the granulation process and re-introduced during the compaction process.
Alexanderwerk has a very attractive and patented solution that features a metered material flow back into its CombiVent chamber in the roller compactor’s feed hopper. Reintroducing off-size recycled granules using such a dual chamber feed hopper design delivers efficient mixing and homogeneous distribution during the granulation process. Check out the results in this article in the latest version of Powder Bulk Engineering (page 35): https://www.e-digitaleditions.com/i/1263839-pbe0720/35?
