The increase in solid fraction (SF) of a packed granule bed with pressure applied during the in-die compression process results in an evolution of the tablet's matrix and mechanical strength. In this case study, the tensile strength (TS) of a dry gra

The bulk properties of a powder are dependent on the preparation, treatment, and storage of the sample, that is, how it was handled. The particles can be packed to have a range of bulk densities and, moreover, the slightest disturbance of the powder

The modern rotary pharmaceutical tablet press is capable of accepting or rejecting individual tablets based on the measured compression force of the tablet. Because during steady operation, each tablet is compressed to the same thickness, a larger co

The blending of powders is a critical step in pharmaceutical drug product manufacturing as it ensures that each dosage unit will contain the same intended fraction of active pharmaceutical ingredient (API). Under-blending thus poses a significant ris

The objective of this work is to measure the adhesive force profile between a punch face and powder compact in-die during the decompression phase of a tablet compaction process. An instrumented punch was developed for use on a single station compacti

The diametrical compression (DC) test, as defined in United States Pharmacopeia1217and in American Society for Testing and Materials testing standard D 3967, has been used extensively to derive the tensile strength (TS) of pharmaceutical tablets from

In recent years, more and more powder blending operations have been augmented with the addition of an intensifier bar (I-bar) in a tumble bin. While the tumble bin rotates with rotational speeds of 5–20 rpm, I-bars rotate at 1000–4000 rpm, with t

Roller compaction is commonly used in the pharmaceutical industry to improve powder flow and compositional uniformity. The process produces ribbons which are milled into granules. The ribbon solid fraction (SF) can affect both the granule size and th

In pharmaceutical development, powder flow characteristics are notoriously difficult to predict. Although tests exist that aim to determine the flowability of powders, many have not been definitively correlated with a powder’s performance in downst
