TOWER FINE MILLING EXPERIENCE AT MOUNT ISA MINES

The Tower mill is a vertical stirred grinding mill which can be used in both dry and wet grinding applications. It has provided a means of size reduction in an area where conventional tumbling mills become inefficient (Morrell et al, 1993). The major advantage of the Tower mills over the ball mills inStirred Milling Technology A New Concept in Fine Grinding,Mill structure The vertical stirred media grinding mill uses a grinding chamber filled with small beads whereby comminution takes place by attrition between the beads. The stirring effect is caused by rotating discs mounted on a shaft. There are also stationary discs on the mill body positioned in Introduction to Machining: Milling Machine,• The type of milling machine most commonly found in student shops is a vertical spindle machine with a swiveling head. Although there are several other types of milling machines, shown is the vertical milling machine. • A milling machine removes metal by rotating a multi-toothed cutter that is fed into the moving workpiece.
