Özet

In this study, breakage behavior of three different coals in a laboratory impact crusher was investigated. The laboratory impact crusher carrying three rows of hammers is rotating at 2,840 rpm driven by a 1.1 kW motor. In the evaluation of crushers, t-family curves obtained from pendulum and drop weight test methods are frequently used. It is a known fact that there are many difficulties and problems in these tests. In this study, a new model was developed by t-family value evaluation and Bond grindability approach and the model was tested. As a result, the validity of the model was proved by a high regression value (r2 = 0.945). © Copyright Taylor & Francis.
