This paper describes the design and use of a tester developed to enable rapid-assessment of the handling characteristics of a coal, which is of importance for the smooth operation of a coal handling plant. The Edinburgh Cohesion Tester is for use of uniaxial unconfined compression of bulk solids. It was designed to be easy to use, portable, robust and relatively cheap. The tester undergoes rigorous testing including checking for test repeatability and sensitivity to the test operator. Additionally, the effects of various factors such as consolidation pressure, moisture content and particle size have been investigated. The results indicate great potential for this cohesion tester.
