monitoring the grinding process of mill rolls

01 Monitoring the liner wear in high throughput grinding equipment is critical if process uptime is to be maximized. The image shows the mill at the Boliden mine at Garpenberg, Sweden where mining has been carried out since at least 375 BC. This mill contributes to the mines production figure of 2.5 million tonnes of ore per year.

Roll Grinder Monitoring – Alta Solutions

Steel and aluminum mills know that monitoring the roll grinding process for quality control improves the performance of work rolls and back-up rolls (BURs) used throughout the mill. Work rolls touch all product surfaces that pass through a mill. Therefore, any pattern or lead line on these rolls is imparted onto the strip surface. Grinding chatter can lead to both 3rd and 5th octave mill chatter, which increases mill downtime and shortens roll

AS-240 Advanced Monitoring of the Roll Grinding

Roll shop operators do not have sufficient information to recognize many grind problems that lead to mill chatter and back-up roll printing. These subtle roll surface variations result in reduced mill productivity and poor product quality. AS-240 GrinderMon™ provides advanced monitoring of the roll grinding process. For the first time, roll shop operators can dramatically reduce hidden roll surface imperfections.

The Maintenance of Rolling Mill Rolls

2021-2-22  Several methods can be used to judge whether the grinding wheel has contacted with the roll: one is to use the grinding indicator; the other is to apply a thin layer of red oil on the surface of the roll, and then make the grinding wheel slowly approach the roll for judgment; in addition, the distance between the grinding wheel and the roll can be judged by observing the water ratio on the grinding wheel or the change of the cooling liquid sound between the roll and the grinding
