THE GRINDING CHARGE OF ROTARY MILLS Prof.Dr.Eng. Gh. Ene "Politehnica" University of Bucharest ABSTRACT This paper presents the achievemens of grinding charge for the tube mills with balls.The author shows charactheristic size of grinding media charge: bulk density, porosity, filling degree. Regarding this last size,the
Ball mill grinding machine is a kind of horizontal drumtype grinding mill with external gear and double bins. Materials goes evenly through quill shaft in feeding device into the first bin, which has ladder lining or ripple lining with steel balls in different specifiions.Steel balls are taken to a certain height by centrifugal force from
The second chamber is the fine grinding chamber. It is lined with classifyingtype mill shell liners and provided with finer ball charge. Classifying liners ensure that the ball charge is segregated along the length of the chamber keeping larger grinding media at the beginning of the compartment and smaller media towards the end of the chamber.

What is the effect of low ball % full on grinding efficiency?One of our clients is thinking of the future and has bought a ball mill that will be the right size someday, but is very large now.I know what happens to mill power from adjustments to % critical speed and % balls charge. What I don''t know
The density of the charge must account for all of the material in the mill including the media which may be steel balls in a ball mill, or large lumps of ore in an autogenous mill or a mixture in a semiautogenous mill, as well as the slurry that makes up the operating charge. Let Jt
Gravityinduced stirred mills initiate a ball charge motion via rotational movement of a screw to provide a size reduction mechanism. In contrast, fluidized stirred mills use a rotational movement to fluidize a mediaslurry mixture, resulting in constant speed to stir the grinding balls and slurry. As the particles are ground, they rise to

The combination of a grinding circuit simulator with a model of ball wear in a grinding mill leads to a method to calculate, with a preselected accuracy, the makeup ball charge that optimizes the operation with respect to a given objective for the grinding process.
In the present invention a method, apparatus and computer program are presented, with which the amount of balls among ore material contained in a grinding mill is estimated as a percentage by volume of the total volume of the mill. Preferably, the invention relates to semiautogenous mills. In the invention, an expanded Kalman filter is used to estimate the ball charge such that measurements
