If a ball mill uses little or no water during grinding, it is a 'dry' mill. If a ball mill uses water during grinding, it is a 'wet' mill. A typical ball mill will have a drum length that is 1 or 1.5 times the drum diameter. Ball mills with a drum length to diameter ratio greater than 1.5 are referred to as tube mills.

Concept of Swirling and Vortex (Unbaffled Tanks) • If a low viscosity liquid is stirred in an unbaffled tank by a centrally mounted agitator, there is a tendency for a swirling flow pattern to develop, for the lighter fluid (usually air) to be drawn in to form a vortex at the surface of the liquid. This reduces the degree of agitation and mixing.
Therefore, ball load could be kept constant by using direct measurement. This article describes the Sensomag and presents some of the major improvements that can be achieved with it. Some other promising avenues are still to be explored. Keywords: Comminution, process control, process optimization, process instrumentation, online analysis.

Typical instrumentation is illustrated in Figure 7.40 for a primary (AG/SAG or rod) mill-secondary ball mill/cyclone circuit. Control of the feed rate is essential, and devices such as variable speed apron feeders or feeder belts, in conjunction with weightometers, are often used.
The mills are now running at 51,500 to 52,000 tons/day, a nearly 5% improvement, which generates an extra $7 million in revenues per year. Based on its success Northgate is planning to use a similar systems to control flotation cells, which accept the output of the ball mills and separate the minerals from the crushed rock.
KIMA Process Control. Innovation, Reliability and Quality Since 1996. ... In contrast to all existing classical methods of ball mills' fill level measurement SMARTFILL is the only system, which measures the sound directly where it occurs: on the mill shell. The structure-born sound sensor only receives the signal directly on the mill body itself.
Ball mills are a special instrument used to break up hard solids into a fine powder. They are similar to rock tumblers in that the instrument is a rotating container filled with heavy balls to grind the substance into powder. Ceramic material, crystalline compounds, and even some metals can be ground up using a ball mill.
