There is a simple Wall Friction Tester available commercially, (from Ajax Equipment (Bolton) Ltd.), which uses a round plastic cell 160 mm in diameter and 25 mm in height, with a stainless... 

An instrument which attempts to measure cohesion was originally developed at Warren Springs Laboratory and is now available from Ajax Equipment (Bolton) Ltd. It is designed to aid the assessment of flow properties of bulk solids in that it measures the cohesive strength of samples of powders in varied states of compaction, from lightly settled conditions to firm compacts. It attempts to measure directly cohesion as defined in section 4.1.2, i.e. the shear stress at failure, with no normal load acting upon the surface of failure. 

The shear cells as used in testing yield strength of solids may also be used for testing friability. As large strain is required in order to produce significant attrition, the annular shear cells (which permit infinite strain) are usually used. A variant on the annular shear cell for attrition testing is available commercially from Ajax Equipment in Manchester. 

I am very grateful to all of the industrialists and academics I have talked to during the preparation of this Guide. I must acknowledge with particular thanks the following people who have made available to me their own notes and written material about the details of test methods quoted in this Guide Dr J. C. Williams and Dr D. Geldart of Bradford University, Mr L. Bates of Ajax Equipment (Bolton) Ltd and Mr M. Walton of Chr. Michelsen Institute. 

AJAX Equipment (Bolton) Ltd Warren Springs Laboratory cohesion tester It is appropriate to include in this chapter an instrument which was one of the first attempts to measure the cohesion of powders directly. It was initially developed at Warren Springs Laboratory, Stevenage, but is now commercially available from AJAX Equipment (Bolton) Ltd.
