| Summary: | The present invention relates to a method and apparatus for testing the compression strength of a granule. More particularly, the present invention relates to a method and apparatus for determining the breakage mechanism involved with the compressive failure of a granule.
A method and apparatus for the accurate monitoring of a granule during compression testing is provided and enables the study of breakage mechanisms that cause particle failure during compression. The method involves compressing a granule or particle with the apparatus and the apparatus is a spring device that combines a spring in parallel with the granule or particle and a spring in series with the granule or particle. Under failure conditions, sudden deformation of the granule or particle results in fast relaxation of the granule or particle during breakage and allows very careful granule breakage. Measuring or recording devices coupled to the apparatus provide for the detailed study of breakage conditions at the moment of failure and lend incite into the compression strength characteristics of the granule or particle. |
