For a ball mill grinding OPC to a fineness of 3200 to 3600 cm2/g (Blaine) the cost of wear parts (ball, liners and mill internals) is typically EUR per ton of cement. For an OK mill grinding a similar product, the cost of wear parts depends on the maintenance procedures, whether hardfacing is applied.

Milling devices used: (a) knife mill, (b) impact mill (IM), (c) rotary ball mill (RBM), (d) stirred ball mill (SBM), and (e) vibratory ball mill (VBM). Before final comminution in the different ball mills, all samples were redried to a moisture content of about 3%, as measured by weight loss after ovendrying for 2 h at 135 °C.

Types of mechanical mills include hammer mills, ball mills, pin mills and roller mills. This variety of mechanical machinery can be used to effectively pulverize powders, but comes with a host of limitations and disadvantages. First and foremost mechanical milling will not allow for reducing particles to the smaller sizes.
