Abstract

The LCPC method is one of the most common abrasion tests used for determining soil and rock abrasivity. LCPC abrasivity coefficient (LAC) and LCPC brittleness coefficient (LBC) are two parameters obtained from this method. The rotation speed (RS) and rotation time (RT) are two factors that affect the results of this experiment. In this paper, the effect of these two factors on quartz and feldspar minerals is investigated innovatively. The tests were carried out in two groups. In the first group tests, the RS was changed from 500 to 4500 rpm, and LAC and LBC were measured at RTs of 1, 2, 3, 4, and 5 min. The results showed that LAC and LBC increase nonlinearly with increasing RS and RT, and the relationship of LAC and LBC with RS and RT is affected by the mineralogy. Experimental relationships between LAC and RT with a coefficient of determination greater than 0.97 were proposed for quartz and feldspar. Study of two-dimensional images of grains showed that the impact of coarse grains on the wear of the impeller is more than that of fine grains. In the second series, the sample inside the container is replaced with a new sample each minute at different RS values. The results showed that by increasing RT, the LAC rate increased as well. Besides, the LAC increased linearly with increasing RT due to the effect of the grain size and shape changes, which were removed during the test. In addition, the effect of the RS on the LAC is greater than that of the RT. Comparing the result of these two series, the optimum rotation time (ORT) is defined as the time when the trend line in the LAC-RT graph changes from linear to logarithmic. This parameter indicates the moment at which the effect of grain shape and size on impeller wear starts to decline. The changes in ORT versus RS for quartz and feldspar are similar and exponential.
