MODULE #5: FUNCTIONAL PERFOMANCE OF BALL MILLING

If a ball mill contained only coarse particles, then 100% of the mill grinding volume and power draw would be applied to the grinding of coarse particles. In reality, the mill always contains fines: these fines are present in the ball mill feed and are produced as the particles pass through the mill.This study aims to develop a new approach toward estimating the Bond ball mill work index (BBWI) by applying a series of kinetic grinding tests with Bond standard mill.

EFFECTS OF GRINDING MEDIA SHAPES ON BALL MILL

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 emitting diode, phototransistor and video photographs were used to determine thelaboratory ball mill. if the mill diameter is greater than 3.81m. The cylindrical . Feed Characteristics . The laboratory ball mill was designed for grinding limestone, meaning that the work index required for the specific power calculation was assumed to be the work index of limestone, which is 11.6 KWh/t, with a specific gravity of 2.6 g/cm. 3Design, Construction and Performance Analysis of a 5 KgLaboratory Ball Mill
