There is no standard solution for mineral industry and wear rate of grinding media varies from mine to mine, ore to ore and even for the same ore time to time. Different alloys are recommended depending on ore type and mill particulars in order to arrive at the most cost economic solution.
It has therefore been shown that the three important chemical conditions which grinding media can affect mineral floatability are: * Concentration of dissolved oxygen * Pulp potential * Opportunity for galvanic interaction between mineral and media. The next section describes these effects on the flotation of specific sulphide minerals.
Figure 8.2 Media motion in the tumbling mill. 8.1 Grinding 8.1.1 Grinding action Industrial grinding machines used in the mineral processing industries are mostly of the tumbling mill type. These mills exist in a variety of types - rod, ball, pebble autogenous and semi-autogenous. The grinding action is induced by relative motion between the
Effect of Ball Size and Properties on Mill Grinding Capacity Current ball milling theory suggests that grinding capacity is influenced by the size of balls charged to the mill. In selecting the appropriate ball charge, the first objective is to determine that ball size which will grind the coarse particles most efficiently. This size should be the largest ball size charged to the mill.
A mill is a device that breaks solid materials into smaller pieces by grinding, crushing, or cutting. Such comminution is an important unit operation in many processes.There are many different types of mills and many types of materials processed in them. Historically mills were powered by hand (e.g., via a hand crank), working animal (e.g., horse mill), wind or water ().
sumption and grinding costs due to media wear. Grinding balls and rods are traditionally used as grind-ing media in the mineral industry. In the recent years other grinding media with different shapes have ap-peared in the market, such as Cylpebs developed by .
