A ball mill, a type of grinder, is a cylindrical device used in grinding (or mixing) materials like ores, chemicals, ceramic raw materials and mills rotate around a horizontal axis, partially filled with the material to be ground plus the grinding medium. Different materials are used as media, including ceramic balls, flint pebbles, and stainless steel balls.

Apr 19, 2013· Efficiency and grinding media filling level Abstract: Advances in materials, instrumentation, monitoring techniques, process knowledge and an ever increasing demand for efficiency and conservation have opened the way to research in areas of comminution that have been overlooked or abandoned time and time again.
Influence of balls filling degree The performance of ball mills is very sensitive to the volumetric mill filling which influences grinding media wear rates, throughput, power draw, and product grind size. A pilot plant investigation with an overflow mill discharge has been conducted.
• Empty heights of both the chambers measured to calculate the ball charge, % filling and estimate the power consumption at mill shaft. Based on the empty height measurements, charging of grinding media in Chambers I II calculated as equivalent to degree of filling of 22% 21% respectively. The estimated

terms of energy requirements and steel consumption related to grinding media and liners. Spherical grinding media are predominantly used in final stages of ore grinding. The spherical balls change shape through breakage and wear. Though this is universal in milling, its contribution and effect on milling kinetics, load behaviour and mill power
Grinding balls are only one type of grinding media. Grinding media are the means used to crush or grind material (cement, mineral, .) in a mill. Grinding media sorting is performed when the ball load wears out. New grinding balls are then added or full reload is carried out to keep optimum filling degree and hence mill performance.

conditions such as mill speed or balls filling degree, should limit the risk of projection. The purpose of this paper is to further explore the issue related to the grinding efficiency. There is probably more to be gained from media angle than a risk of breakage only. Table I illustrates or quantifies the media .
2. Grinding media The grinding media used are, generally, balls and cylpebs. In compartments of coarse and medium grinding are used balls, and in that of fine grinding, balls or cylpebs. In any compartment, sizes of grinding media must be correlated with the size of the material. Between the balls are formed free spaces (emptiness).
