A wet grinding ball mill in closed circuit is to be fed 100 TPH of a material with a work index of 15 and a size distribution of 80 passing inch 6350 microns. The required product size distribution is .
Ball mills are customarily divided into categories that are mainly defined by the size of the feed particles and the type of grinding media. Intermediate and fine size reduction by grinding is frequently achieved in a ball mill in which the length of the cylindrical shell is usually 1 to 1.5 times the shell diameter.

Grinding media size distribution in ball mill. The Azzaroni equation indicates that the correct ball size for the 293 m mill is 81 mm Years of experience show that a 76 mm ball grinds the coarse particles most effectively Ball size distribution is governed by the wear law of the mill and by the wear characteristics through the crosssection of ...
Jul 25 2017018332Grinding Media Ball have a significant impact on the performance of grinding mills in terms of product size distribution energy consumption and grinding costs. The below Figure shows main grinding costs for the specified mills.
Key properties of grinding media include composition hardness size and density. Some common types include alumina stainless steel yttria stabilized zirconia and sand. Ball milling will result in a ball curve particle size distribution with one or more peaks. Screening may be required to remove over or undersized materials.
The cement grinding process in this system is rather simple with less equipment required. The finished product cement from this system has all been further ground in the ball mill so it has wide particle size distribution and stable performance.
The objective of this dissertation was to investigate how media shape affects grinding. Ball size distribution inside an industrial mill was analysed in terms of shapes and sizes. Load behaviour mill power and breakage as affected by media shapes were studied in a pilot laboratory mill. An inductive proximity probe light
The present study is taken to control the particle size distribution and reduce the specific energy consumption in an industrial ball mill. A batch mill of 2.21m diameter and 2.43m is used for grinding silica from average size of 3mm to 100 below 80 microns.
Which can grind efficiently in a mill c is the exponent which characterizes the ball size distribution. The condition for efficient grinding defined by Eq. 7 will be fulfilled when the grain size distribution and the ball size distribution are the same which means that the parameters of both distributions are equal in Eqs. 7 and 9: m c. 10
