Absorptometer "C"
The Brabender Absorptometer "C" is a tabletop instrument with a torque measurement system (dynamometer), which is used for the precise and reproducible determination of the oil absorption number (OAN) of powdery materials. The test method is based on the changes of the consistency of powdery materials during oil absorption.

Effect of High‐Energy Ball Milling and Silica Fume ...
· Silica fume was further added in the raw mixtures to observe its role on the cementing phase formation. Results indied that the decomposition temperature of BaCO 3 lowered remarkably with the increase in milling time. Barium aluminate cements with grain size in nanometer range were obtained from highenergy ballmilled raw mixtures.

Silica dust
Air monitoring for silica dust. The mandatory limit for silica dust exposure in Australia is /m 3 averaged over an eighthour day (except in Tasmania where it is /m 3), although the American Conference of Governmental Industrial Hygienists (ACGIH) have recommended this be limited to mg/m 3.. However, there is no evidence to support a safe level of silica dust .

API Particle Size Reduction, Milling, Micronization ...
Micronization is a commonly used method for PSD. It allows reduction of the API particle to a micrometer size. This technique helps process heatsensitive products, because the temperature remains relatively constant throughout the process. Polpharma API has two jetmill micronizers, one in its manufacturing plant and one in the pilot plant.
