Most of the causes of multimill malfunctions such as oversized granules, excessive fines, screening problems, or motor overloads are related to blade dullness, incorrectly sized screens, or improper feed rates. In this article, you will find 8 failure modes with their potential causes and solutions for your pharmaceutical granulation process.
Even a well-maintained colloidal mill experiences recurring issues that lead to malfunction eventually, and usually, there are only several common causes for that: the gap drift, rotor/stator wear, improper feed rate, or a faulty mechanical seal. Moreover, preventing the issues from arising is significantly simpler and less resource-consuming than addressing them after they occur. For … Read more
Have you ever asked yourself why a tablet, which has passed all the other quality control tests, fails the QC bench? A disintegration test apparatus is used to determine whether a tablet or a capsule disintegrates within a specified time under defined conditions. The test is performed by vertically reciprocating the unit in a liquid maintained at human body temperature. This article describes the working principle of the disintegration test apparatus, its components, the procedure for the disintegration test, calibration, and the disintegration limits set by the manufacturers for different dosage forms. This information will help QC and manufacturing personnel to perform the disintegration test properly and release the batches of the pharmaceutical products.
