Classification in a ball milling circuit may be done using

In a ball mill circuit, the output can be defined as the production rate of fines of the circuit. As for any output, ball mill circuit output is a function of both its inputs and efficiencies. There are two inputs to a ball mill circuit: the ore fed to the circuit and the power delivered by the grinding mill

    The right determine of SAG feed size. This depends on the mill diameter and the ball size. Feed size necessary to take 80% of the maximum piece of ore that will crushed by the balls. For the big SAG more than 8 meters optimal feed size will be - 50mm. Ball size - 120 ... 125mm. Do not a pebble crushing, the need secondary crushing

All flanges are double welded as well as steel head to shell, note design. Tumbling Mill (Rod or Ball) Mill TYPE E Has quadruple flanged construction. This also furnishes mill heads in two sections flanged and bolted in the center

    8.3.2.2 Ball mills. The ball mill is a tumbling mill that uses steel balls as the grinding media. The length of the cylindrical shell is usually 1–1.5 times the shell diameter ( Figure 8.11). The feed can be dry, with less than 3% moisture to minimize ball coating, or slurry containing 20–40% water by weight

    If you need to add water to the feed end of your ball mill to control the density, by all means do so, but make sure you decrease water addition by an equal or greater amount elsewhere in the circuit (e.g. SAG feed or cyclone feed) or the overload will continue to escalate once the immediate benefits are overtaken by increased circulating load

    Ball milling technique, using mechanical alloying and mechanical milling approaches were proposed to the word wide in the 8th decade of the last century for preparing a wide spectrum of powder materials and their alloys. In fact, ball milling process is not new and dates back to more than 150 years. It has been used in size comminutions of ore, mineral dressing, preparing talc powders and many
