Rod mills are less common than ball mills for grinding minerals The rods used in the mill, usually a high-carbon steel, can vary in both the length and the diameter However, the smaller the rods, the larger is the total surface area and hence, the greater the grinding efficiency

Ball mills are among the most variable and effective tools when it comes to size reduction of hard, brittle or fibrous materials The variety of grinding modes, usable volumes and available grinding tool materials make ball mills the perfect match for a vast range of applications

Figure 2 shows the active grinding area for an optimally charged ball mill As the drum rotates, the media should ideally form a sloping pile that maintains a 45 degree angle so that there is a constant cascading of media at the surface Because the media is falling the fastest and for the longest distance at the top of the pile, the majority

The forged steel ball is selected from the best quality of carbon and alloy steels as well as forged due to more density and strengths Most importantly, we can accept the all grinding with enhanced the forging process ensuring spherical ball shape is very reliable and supplies grinding products for ,

In Grinding, selecting (calculate) the correct or optimum ball size that allows for the best and optimum/ideal or target grind size to be achieved by your ball mill is an important thing for a Mineral Processing Engineer AKA Metallurgist to do Often, the ball used in ball mills is oversize “just in case” Well, this safety factor can cost you much in recovery and/or mill liner wear and ,

Larger grinding media has a smaller grinding surface area, but offers a heavier weight that’s generally used to break larger ore Small grinding media has a larger grinding surface area generally chosen to help make smaller ore smaller In some cases, we find ourselves adjusting the ball size by the millimeter to approach optimization
