Industrial Solutions quadropol QMR² - ThyssenKrupp

The grinding table – and thus the grinding rollers – of the QMR² mill are set in motion by a motor with a gear unit. The rotating grinding rollers are pressed onto the bed of material by means of a hydraulic cylinder. As the grinding table rotates faster than the grinding rollers, it presses the material under the roller.


Industrial Solutions quadropol QMC²

As roller units, grinding table and gear unit do not have any contact with the mill housing, the grinding forces are directly transmitted into the foundations. No grinding forces act on the mill housing; the outer grinding-roller seal between the roller and the housing minimises the intake of false air. Visual inspections may be per-

Monitoring the fill level of a ball mill using vibration ...

Ball mills are extensively used in the size reduction process of different ores and minerals. The fill level inside a ball mill is a crucial parameter which needs to be monitored regularly for optimal operation of the ball mill. In this paper, a vibration monitoring-based method is proposed and tested for estimating the fill level inside a laboratory-scale ball mill. A vibration …


FOR VERTICAL ROLLER MILLS - Loesche

Reduction of vibration levels Roller mills are constructed of major mechanical components that can be easily damaged by high mill vibrations. It is very important that a mill is operated in a stable manner and that corrective actions are taken to prevent damage to mechanical equipment and mill outages that result in lost production.
