Investigation of the gouging abrasion resistance of materials in the mining industry Tolfree, Donald
Abstract
With increased budget constraints, innovative cost reduction methods are required to increase the profitability of today's mines. Abrasive wear reduction is a novel way to reduce costs and increase productivity. Specifically, gouging abrasion is making an increased contribution to abrasive wear losses in the oil sands industry. To assess material property requirements for mitigating this wear mechanism, jaw crusher gouging abrasion tests using a modified ASTM G81 procedure, have been carried out on a range of wear materials of interest for oil sands mining service. The method involves a comparison of the wear losses that occur for reference and selected test plates when a controlled amount of standard feed rock is comminuted in a laboratory jaw crusher. Among the classes of material evaluated have been Q&T plate steels, austenitic manganese steel, chromium and chromium molybdenum white irons as plain castings and in laminated forms and also chromium carbide and tungsten carbide overlaid wear plates. In addition, the initial stages of relationships are presented relating wear rates/factor, determined from the laboratory gouging abrasion test, to the quartz content of the abrasive material. Of all the materials tested, the laminated CrMo white consistently had the lowest wear factor (best gouging abrasion resistance). From the data produced by this work, the wear factor has a linear relationship with quartz, while the wear rate has a non-linear relationship.

With increased budget constraints, innovative cost reduction methods are required to
increase the profitability of today's mines. Abrasive wear reduction is a novel way to
reduce costs and increase productivity. Specifically, gouging abrasion is making an
increased contribution to abrasive wear losses in the oil sands industry. To assess material
property requirements for mitigating this wear mechanism, jaw crusher gouging abrasion
tests using a modified ASTM G81 procedure, have been carried out on a range of wear
materials of interest for oil sands mining service. The method involves a comparison of
the wear losses that occur for reference and selected test plates when a controlled amount
of standard feed rock is comminuted in a laboratory jaw crusher. Among the classes of
material evaluated have been Q&T plate steels, austenitic manganese steel, chromium
and chromium molybdenum white irons as plain castings and in laminated forms and also
chromium carbide and tungsten carbide overlaid wear plates. In addition, the initial stages
of relationships are presented relating wear rates/factor, determined from the laboratory
gouging abrasion test, to the quartz content of the abrasive material. Of all the materials
tested, the laminated CrMo white consistently had the lowest wear factor (best gouging
abrasion resistance). From the data produced by this work, the wear factor has a linear
relationship with quartz, while the wear rate has a non-linear relationship.
