    Abstract

    ASTM Standard Practice G 81-83 describes a laboratory procedure for determining the relative gouging abrasion resistance of materials in a jaw crusher. The authors have found a number of problems associated with the test procedure, particularly in respect of its inefficiency, the fact that it yields biased estimates of the wear parameter, and its lack of facility for assessing the significance of differences between test results. An alternative methodology for conducting the tests and for analyzing the data is proposed, and it is shown, by example, how substantially more information can be obtained from tests results than has hitherto been demonstrated.
