Roll crusher liner wear investigation and experimental study

摘要

Wear on the surface of the rolls of the roll crusher is very common during crushing. The wear zones on the rolls have been identified as sliding zone and compression. In the present study wear in sliding zone has been investigated using the damaged liner of the rolls. The study was carried out to identify the wear mechanisms obtained on the rolls. To correlate the wear mechanisms obtained in sliding zone, dry sliding abrasive wear experiments has been processed further. The dry sliding abrasive wear experiments were also used to find out the weight loss. This was performed using statistical modelling to identify the effects of wear parameters on weight loss. The obtained results of equation in statistical modelling confirmed the validity of the wear model. The surface of the test samples was examined under field emission scanning electron microscope to validate the results of wear mechanisms of liners.
