Axial transport in dry ball mills - ScienceDirect

Nov 01, 2006 These studies give reasonable confidence that the flow behaviour predicted accurately represent real particulate motions in dry mills. In this paper we turn attention to the axial transportation of fine material in a ball mill that is able to discharge from one end. This requires simulation of the entire mill length. 2. Discrete element method

AXIAL TRANSPORT IN DRY BALL MILLS

AXIAL TRANSPORT IN DRY BALL MILLS Paul CLEARY CSIRO Mathematics and Information Sciences, Clayton, Victoria 3169, AUSTRALIA ABSTRACT Ball mills are used for grinding of rocks, cement clinker and limestone from 10-100 mm feed sizes down to sub-millimetre product. They are typically rotating cylinders with diameters from 3-6 m and lengths from 6-12 m

In this paper, we examine the axial transport in dry ball mills. This requires simulation of the entire mill and the full volume of the charge for significant periods of time (thousands of revolutions). We use a simple model for grate discharge that allows prediction of the time varying axial distribution of different particle sizes within a discharging ball mill

RADIAL AND AXIAL MIXING OF PARTICLES IN A DRY

Radial and Axial Mixing of Particles in a Dry Batch Ball Mill _____ ii Abstract Mixing is an important operation that is carried out in food, paint, pharmaceutical and mineral processing industries. Ball mills are one of the many mixing vessels used in a mineral processing industry. During grinding, the mill’s efficiency depends on
