Ball mills, that are commonly used for finish grinding, have high energy demands, consuming up to 30-42 kWh/t clinker depending on the fineness of the cement. Complete replacement of ball mills by vertical roller mills (VRMs) with an integral separator – as opposed to the use of VRMs as pre-grinding to ball mills – is regarded as a breakthrough.

HTPM series milling cutters have unequal flute spacing (variable pitch) and multiple helix angles (35° and 37°) to reduce chatter and harmonics, for improved stability and better finishing. This also optimizes chip formation and chip evacuation. These 4-flute end mills feature a spherical ball end. Aluminum Chromium Nitride (Hybrid AlCrN) coating reduces wear and increases heat resistance.

For overflow ball mills, the charge should not exceed 45% of the mill volume . For grate discharge mills, the charge should occupy about 50% of the mill volume . Bond developed a relationship that can be used to determine the percent charge by volume as a function of the vertical height above the charge, He, and the radius of the mill, R, i.e.,
