MГ©langeur-3D- Turbula-T2F-T10B-T50A-Labo Services. 21/12/2012В В· Blending of powders is a crucial step in the production of pharmaceutical solid dosage forms. The active pharmaceutical ingredient (API) is often a powder that is blended with other powders (excipients) in order to produce tablets. The blending efficiency is influenced by several external factors, The effects of various factors on viscosity are summarized in Figure 1.5 following Cogswell [3]. Linear narrow molecular weight distribution polymers (e.g. metallocenes) are more viscous than their broad distribution counterparts. Fillers may increase viscosity (greatly)..

Powder mixing of cobalt and nickel was achieved by using a Turbula shaker mixer at a rotational speed of 49 rpm for 6 h where both translational and rotational motions were applied. Powder mixing is a very old and common operation performed instinctively by humans since the dawn of time with as first tools hands, poles, spoons and shovels. The need for mixing growing volumes and the formulation of more complex powders for industrial applications led to the design of numerous mixing devices in order to achieve homogeneity at specific scales.
