Dec 23, 2013 Introduction Ball milling is a method used to break down the solids to smaller sizes or into a powder. A ball mill is a type of grinder which consists of a cylinder. It is used in grinding (or mixing) materials like ores, chemicals, ceramic raw materials and paints. The cylinder rotates around a Principle of Ball Mill Ball Mill Diagram. The balls occupy about 30 to 50 percent of the volume of the mill. The diameter of ball used is/lies in between 12 mm and 125 mm. The optimum diameter is approximately proportional to the square root of the size of the feed. The shell is rotated at low speed through a drive gear (60-100 rpm) and ...

The ball mill is a tumbling mill that uses steel balls as the grinding media. The length of the cylindrical shell is usually 11.5 times the shell diameter (Figure 8.11).The feed can be dry, with less than 3% moisture to minimize ball coating, or slurry containing 2040% water by weight. Oct 28, 2021 The water can wash away the fine particles in time to avoid over-grinding. The wet ball mill has a low noise, and low environmental pollution. The wet ball mill has a simple transportation device with less auxiliary equipment, so the investment is about 5%-10% lower than that of a dry ball mill. The grinding particle size is fine and uniform.
