The vertical roller mill (VRM) is firmly established in cement plants all over the world. The biggest issues facing plants are not due to the equipment itself, but more to do with how well mill maintenance is understood and how the mill is looked after following commissioning.
The paper shows the possibility to produce marble nanoparticles in a stirred media mill by appropriate milling parameters. In this study, marble wastes in the form of large pieces from Marfam Marbles factory were crushed below -1 mm and then dry grinding of wastes were investigated in a laboratory scale pin-type vertical stirred mill.
Apr 23, 2021 Different Types of Machining Operations. Two primary machining processes are turning and milling descried below. Other processes sometimes dovetail onto these processes or are performed with standalone equipment. A drill bit, for instance, may be installed on a lathe used for turning or chucked in a drill press.

Mills usually operate in the range 65 - 82% of critical but values as high as 90% are sometimes used. A crucial parameter that defines the performance of a mill is the energy consumption. The power supplied to the mill is used primarily to lift the load (medium and charge). Additional power is required to keep the mill rotating.
