9.3.4 Mill Speed During normal operation the mill speed tends to vary with mill charge. According to available literature, the operating speeds of AG mills are much higher than conventional tumbling mills and are in the range of 80–85% of the critical speed.
Stop the mill and remove the speed change plate. Unwind the chain for a look inside. Remember to draw the chain up with a bit of tension after peeking inside. Else the vari-disc will have a snap speed change because of the slack. Thinking about the original problem and taking a peek. Why not run the mill up to the 2000 rpm limit.

milling. For many years it was common practice to mill against the direction of the feed due to the absence of backlash eliminating devices and the use of high speed steel cutters. This method is called conventional milling. In conventional milling, friction and rubbing occur as the insert enters into the cut, resulting in chip
In recognition of ore variability, many current SAG mills are installed with variable speed drives, capable of operating the mill through a wide and continuous range of speed values. Mill speed and liner profile determine grinding media trajectories, as shown in Figure 1. By increasing mill speed or the steepness of liner attack angle,
Ball mills have been successfully run at speeds between 60 and 90 percent of critical speed, but most mills operate at speeds between 65 and 79 percent of critical speed. Rod mills speed should be limited to a maximum of 70% of critical speed and preferably should be in the 60 to 68 percent critical speed range.
Mill Speed is one variable that can often be easily changed with a variable frequency drive (VFD). The starting point for mill speed calculations is the critical speed. ... Dry mills typically operate in the range of 50%-70% of CS and most often between 60%-65% of CS.

For best results, the speed of the spindle should be between 150 and 250 rpm. Get a tap guide. The hole is now ready to tap. To do this, use the taps and guide blocks near the manual mills. The guide blocks will have several holes for different sized taps. Select the one closest to the size of the tap being used and place it over the drilled hole.

Cutting speed, also known as surface speed, refers to the speed at the outside edge of the tool as it is cutting. It is measured in surface feet per minute (SFM). Cutting speed is mainly depending on the type of materials and cutting tools, related to their hardness. The harder the material, the slower the cutting speed should be.
