Lab Report 1 and 2: PRACTICAL 1 : BALL MILLING

28/12/2013 · Ball Mill is the equipment to be used for size reduction. It is a kind of grinder used for intermediate or fine grinding. Ball mill is a metal cylinder which rotates about its horizontal axis. The coarse sugar charged along with the metal balls breaks to fine powder by impact of metal balls.

Ball mill operation is often regarded as something of a mystery for several reasons. Ball milling is not an art it's just physics. The first problem will ball mills is that we cannot see what is occurring in the mill. The other problem is that many of the independent variables are nonlinear or have paradoxical effects on the end results.

Apr 26, 2017 · Figure 1 shows a SEM image of magnesium powders before ball milling, and these powders have an average size of ~40 µm and possess an irregular and flakelike shape. After being ballmilled for 160 min, some magnesium powders were deformed and reduced in size as exhibited in Figs. 2a and 3a. As indied by the arrows in the figures, some powders were curled around the edge after ball milling.

Ball mill

A ball mill is a type of grinder used to grind or blend materials for use in mineral dressing processes, paints, pyrotechnics, ceramics, and selective laser works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell. A ball mill consists of a hollow cylindrical shell rotating about its axis. T
