Mills are classified into two general types namely, vertical and horizontal. The key difference between the two is the orientation of the spindle, a component of the mill that holds the cutting attachment. While the two mill types work similarly, it's important to understand that they have varying capabilities. Vertical milling machine

Horizontal milling machines feature short and thick tools capable of removing large amounts of material from the workpiece compared to vertical milling machines. Vertical milling machines feature long and thin tools. The difference in cutting tool geometry affects the nature and accuracy of the cuts each machine is capable of.

Brissett (2010) reviews several industrial cases of stirred milling against ball milling. Vertical mills can operate at higher volumetric load (6085%v/v) than ball mills (3545%v/v), which then leads to higher productive throughput capacity (tph/m3). Fig 2 shows that that savings for a vertical mill can range from

Vertical stirred mills may be classified according to the speed of the stirrer in two groups: gravityinduced or fluidized mills [[1], [2], [3]]. In the gravityinduced mills, the stirrer, generally of the screw type, turns so that the grinding charge exhibits an ascending convective motion at the center, descending from the edges of the screw ...
