Vertical Milling Machines. In vertical mills, the spindle axis is vertically oriented. Milling cutters are held in the spindle and rotate on its axis. Typically the spindle can be extended or the table raised or lowered to produce the same effect, allowing for plunge cuts and drilling. The two kinds of vertical mills are bed mills and turret mills.

Ideal for grinding finer products, stirred mills are known for their energy efficiency and compact design, reducing floor space requirements. These mills are based on gravityinduced and fluidized technologies, allowing for the optimum equipment solution for all comminution circuits covering secondary, tertiary, fine, ultrafine, regrind, and lime slaking applications.

The grinding action in the vertical mill is mostly by shear, torsion stresses and compression forces produced by the stirrer rotating at high velocities. The result is abrasion by the grinding media on the mineral particles. ... N = number of revolutions per second (s −1) N m = number of grinding media per unit volume (m −3) t = grind time (s)

"Two principal milling operations are slab milling and face milling. Slab milling uses the peripheral edges of the milling cutter to make planar cuts across the surface of a workpiece. Keyways in shafts can be cut using a similar cutter though one that is narrower than the ordinary slab cutter. Face cutters instead use the end of the milling ...
