A ball mill is still the preferred solution for many types of dry grinding duty. A ball mill consists of a rotating horizontal cylinder, containing a cascading grinding media, typically steel or ceramic balls, in the range of 10 to 100 mm diameter. The grinding mechanism takes place within the falling and sliding grinding media.

Abstract Prediction of continuous steady-state ball milling using the traditional population balance model requires knowledge of several functions, namely those describing the rate and distribution of breakage products, the mass transfer relationship between the mill hold-up and the discharge, the mode of transport within the mill, as well as the description of internal classification ...

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 viscosity and density of air, whereas with wet milling

This paper presents the development of a mill scale-up procedure based on population balance models of grinding circuits. Models containing various degrees of details in their representation of the kinetics of breakage, material transport through the mill, and performance of the classifier are examined; and the extent to which each may be useful for design is discussed.

2017-7-20 Autogenous grinding is favored when the ore is quite competent and a fine grind is required. Semi-autogenous grinding is applied when fine crushing could cause severe problems or when ore is variable in hardness or competency. Figure 2 shows a typical conventional crushing-grinding circuit with three stages of crushing followed by ball mills or ...
