Introduction. The control of the raw mill feed before the raw mill and the raw meal after the mill is still indispensable. Because of the complexity and the significance of the control process, various automated systems are available for sampling and analysing the raw mix as well as for adjustment of the mill weight feeders according to the raw meal chemical modules in mill outlet or inlet [1].

The vertical roller mill (VRM) shown in Figure 4 is an air swept, mediumspeed, vertical pulverizer with integral classifier. It pulverizes coal by applying hydraulicallyloaded grinding pressure through three grin ding rollers onto a rotating bed of coal. Grinding pressure can be adjusted to account for variations in coal

The mill feed material needs to be free of metal pieces. Higher the metal pieces frequent operation of diverting gate and results in feed variation. [8,12,14] Abnormal feed size and distribution may increase the level of vibration and destabilize the mill. Large feed size in any case will reduce the mill production rate. Excess fines in the feed

Conventional milling with a face mill causes the chip to start out thin, which sometimes leads to rubbing at the outset of chip formation that is bad for surface finish and can lead to BUE. The best finishes start the chip out fat and then thin it out before the chip releases. Take a light cut when finishing: ″

On Vertical Mills, the 4th Axis is frequently parallel to X or Y, and is laid down. On a Horizontal Mill, the 4th Axis is also parallel to X or Y, but it is standing up. Both methods work great, but the horizontal mill's standing 4th axis frequently has more clearance available since the work is never trapped between the table and the axis.
