    In ball mills, steel balls or hard pebbles to break particle based on impact and attrition. A rotating mill charged with media and ore is lifted against the inside perimeter. Some of the media falls and impacts the ore particles at the bottom of the mill. The rest of the media cascades and, in the process, creates particle breakage by attrition.

    Grinding control strategy on the conventional milling

    There are six parallel conventional milling circuits at Palabora Mining Company. Each milling circuit consists of a rod mill followed by a ball mill in series. Crusher product (-9 mm) is fed to the rod mill, and the water is fed in ratio to the ore feed mass. The rod mill discharge is pumped, without any further water addition, to the first ball mill.

    Autogenous mills range up to 12 meters in diameter. The length-to-diameter ratios in the previous table are for normal applications. For primary grinding, the ratio could vary between 1:1and 1.8:1. For fine regrinding in open circuit, the ratio ranges from 1.3:1 to 1.5:1. Some ball mills are separated in to compartments by grates.

    F 80 is the mill circuit feed size in micrometers. Rod mill. A rotating drum causes friction and attrition between steel rods and ore particles. [citation needed] But note that the term 'rod mill' is also used as a synonym for a slitting mill, which makes rods of iron or other metal. Rod mills are less common than ball mills for grinding minerals.

    Ball Mills 911 Metallurgist

    13-02-2017· Ball Mill Grinding Circuit. Even though many ores require fine grinding for maximum recovery, most ores liberate a large percentage of the minerals during the first pass through the grinding unit. Thus, if the free minerals can be immediately removed from the ball mill classifier circuit, there is little chance for overgrinding.

    Milling Process, Defects, Equipment

    End milling An end mill makes either peripheral or slot cuts, determined by the step-over distance, across the workpiece in order to machine a specified feature, such as a profile, slot, pocket, or even a complex surface contour.The depth of the feature may be machined in a single pass or may be reached by machining at a smaller axial depth of cut and making multiple passes.

    Selection of Comminution Circuits for Improved Efficiency

    Fully autogenous circuits are attractive due to the elimination of steel media costs. Typically, a SAG mill based circuit (P80 of 106 to 150 um) has media costs of around A$1/t. Providing the ore is amenable, the use of primary autogenous milling can reduce this cost by 40%. Autogenous milling is typically practiced in association with
