We can calculate the steel charge volume of a ball or rod mill and express it as the % of the volume within the liners that is filled with grinding media. While the mill is stopped, the charge volume can be gotten by measuring the diameter inside the liners and the distance from the top of the charge to the top of the mill.

CHAPTER 4 104 Survey meters come in different shapes and sizes, depending upon the specific application (see Fig. 4.2). The gas is usually a non-electronegative gas in order to avoid negative ion formation by electron attachment, which would increase the collection time in the detector, thus limiting the dose rate that can be monitored.

The ball charge and ore charge volume is a variable, subject to what is the target for that operation. The type of mill also is a factor as if it is an overflow mill (subject to the diameter of the discharge port) is usually up to about 40-45%. If it is a grate discharge you will have more flexibility of the total charge.

On the other hand, piezoelectric transducers have extremely wide measuring range. In other words, with a piezoelectric transducer it is possible to measure down to a few pe (e-strain m/m) and still have a measuring range of a few me. Normal strain gauges (wire or metal) have a threshold of about 20 ne and a measuring range of 1 me.
