I. INTRODUCTION Ball mill is vital equipment used in industries for mineral dressing, ore processing, fertilizers, paint industries, food and diary, pharmaceuticals and many others. In ball mills, the energy input to the pigment dispersion is provided by the rotation of the mill, so that the hard balls within the mill are tumbled with, or onto, the pigment in the mill.

2020-11-1 Abstract. A modified three-dimensional quasi-wet discrete element method (DEM), which is constructed by adding the drag force and buoyancy and the velocity dependence of the friction coefficient of a ball to a conventional dry DEM model, is proposed for analyzing the impact energy of balls in wet ball-milling processes.

2017-5-25 The choice between wet and dry milling is, in general, unimportant in small-scale milling but is a major technical problem when large-scale milling in the metallurgical industries is involved. On purely mechanical grounds it is difficult to see any great difference in fundamental principles between wet and dry milling, since dry milling may be regarded as wet milling with a fluid having the ...

Abstract The present study deals with an analysis of the selection function for mills using balls as grinding media. The grinding mechanism assumes that a particle caught by two colliding balls will be ground only if the ball impact generates or activates at least one single crack within the particle causing the fragmentation. The derived selection function becomes convex in relation to ...
