摘要：Summary There are several techniques such as surface profilometry, advanced technique of electron microscopy and optical methods which have been used by researchers to determine the measurement of wear and it is found useful to understand the surface geometry of the material. In mining industries, wear is acute in rock crusher. This work explores the characterization of wear observed on the surface of liner material of roll crusher crushing coal. Wear characterization like ploughing, scratching, cavities has been observed on the surface of liners. To correlate wear characterization due to abrasion on roll crusher liner wear, experiments have been performed. To perform abrasive wear test, pin-shaped sample of liner material has been developed for the purpose of testing. The abrasive wear experiment was conducted using pin-on-disc tribometer. During the investigation, experiments based on full factorial design adopted from statistical modelling software. In this methodology, the input parameters like load, sliding distance, hardness of coal, hardness of liner material are taken into consideration, and weight loss was considered as the output response. The influence of each input parameters were examined to understand its effect for weight loss. The regression equation obtained from analysis of variance table was used for the prediction of weight loss. The regression equation developed was validated with the experimental results. The percentage error was observed less than ±10%.
