Ball mill is a fine grinder. A horizontal or vertical rotating cylinder which is filled partially with the balls of ceramics, small rocks and balls made from stainless steel. The ball charge of a SAG mill is about 29% to 30%. By friction and influence of tumbling balls inside rotating cylinder grinds the raw material to the required fineness. Get price >>
The grinding programs were performed in a planetary ball mill Retsch PM 100, using a 500 mL zirconia pot and zirconia balls (120 mL, diameters 5, 10, and 20 mm). The volume of processed material per cycle was 80 g. Two grinding routes were evaluated: wet grinding and dry grinding. Get price >>
2020-12-12The ball size in a mill has a significant influence on the mill throughput and power consumption. Here the ball size refers to two aspects, one is the maximum ball size, and the other is the correct ball size ratio. The size of the grinding media directly affects the grinding efficiency and product fineness. Get price >>
A grinding ball works on the principle of impact and attrition. For each specific alloy there is a constant hardness of all grinding media grinding ball. This creates a positive influence in the down-stream process. high-Chrome grinding media grinding ball is suitable for both wet and dry ore applications in grinding ball mills and grinding Get price >>
