Investigation on measuring the fill level of an …
01.11.2009 · Kolacz (1997) proposed a method to measure the fill level by using a strain transducer. The transducer was installed at the middle of the mill shell. When the transducer moved to the top position of the mill shell, it measured the compression. After half a revolution, the transducer reached the bottom of the mill shell, the tension being measured.

Optimization of mill performance by using
The complete grind-out is required to obtain the accurate ball load measurement or the percentage by volume of balls in the mill. This is usually performed soon after a crash stop. The basic principle is to measure the height ‘H’ from the charge to the shell and the internal mill diameter ‘Di’.
Mill (grinding) - Wikipedia
Ball mill. A typical type of fine grinder is the ball mill.A slightly inclined or horizontal rotating cylinder is partially filled with balls, usually stone or metal, which grind material to the necessary fineness by friction and impact with the tumbling balls. Ball mills normally operate with an approximate ball charge of 30%.

Ball Mill - an overview | ScienceDirect Topics
Ball mills are filled up to 40% with steel balls (with 30–80 mm diameter), which effectively grind the ore. The material that is to be ground fills the voids between the balls. The tumbling balls capture the particles in ball/ball or ball/liner events and load them to the point of fracture. When hard pebbles rather than steel balls are used for the grinding media, the mills are known as ...
