Measurement and Use of Bulk Solids Flow Properties
Dr. Johanson has written many papers explaining ways in which Indices can be used. These articles explain how the Indices can help to solve problems in hoppers, processes, designs and quality controls.
This article describes the Indices, their measurement using small samples, and their application to pharmaceutical equipment selection, design and operation. Jerry R. Johanson. Pharmaceutical Manufacturing International 1995, pp.159-164.
This article proposes a standard for judging any bulk solids handling characterization system and then evaluates several existing systems against this standard. Jerry R. Johanson.
This article considers a bimodal mixture, relating each component's properties to its segregation tendencies, when caused by the five most frequently encountered segregation mechanisms. Johanson, J.R. Pharmaceutical Technology, Vol. 20, No. 5, pp46-57 and Pharmaceutical Technology Europe, Vol. 8, No. 1, January 1996, pp. 38-43.
Test methods provide guidance on storage methods for materials with caking tendencies. Focuses on outdoor storage and crystal growth within materials. Johanson, J.R. Chemical Processing. Vol59, No. 8, August 1996, pp71-75.
Compares the Johanson Indicizer to the Jenike Shear Cell from the perspective of Dr. Jerry R. Johanson. Dr. Johanson first worked on improving the Shear Cell under the direction of Dr. Andrew Jenike in 1958. Johanson, J.R. Bulk Solids Handling, Vol. 12, No. 2, May 1992, pp.237-240
How a powder's physical functionality often determines the success or failure of pharmaceutical processing. Johanson, J.R. Innovations in Pharmaceutical Technology, second edition, 1999, pp. 136-146.
