A ball mill is another type of milling machine that uses balls to crush material. The ball mill is made up of a hollow section that spins down either a horizontal or a vertical axis. The section is packed with balls. The materials to be crushed are added and the balls move around inside the mill, colliding with the materials.

WhatsApp: +86 18203695377The ball mill is a tumbling mill that uses steel balls as the grinding media. The length of the cylindrical shell is usually times the shell diameter (Figure ).The feed can be dry, with less than 3% moisture to minimize ball coating, or slurry containing 2040% water by weight.
WhatsApp: +86 18203695377The quality and surface area of forged steel balls of various sizes are shown in Table 112. A kind of Because of the wear of steel balls in the mill production process, in order to keep the mill stable. Steel balls need to be added regularly. The maximum diameter of additional steel balls is still determined by the method mentioned above.
WhatsApp: +86 18203695377Chrome alloy steel balls comprise about 90% of all balls manufactured. This material is a high carbon (%), chrome (%) alloy steel that will harden into the 60 65 HRC range when oil quenched from a soaking temperature of 1475 ° F. The hardness usually ends up at 62 HRC.
