The dam ring height is the height measured from the grinding table segment to the top of the dam ring. For vertical mills the dam ring height is often referred to as "% of table diameter". The optimum height normally being in the range 2.5 - 4% of table diameter. Example: A dam ring of 120 mm in an Atox 32.5 will give a relative height of: 120 ...

The equipment costs are higher for a VRM than a ball mill, reflecting the greater complexity of the system, which includes items such as the rollers, table and the hydraulic system. Overall, when equipment, erection and civil costs are taken into account, the cost of a VRM project is around 20 – 25% greater than a ball mill system of the same ...

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 0.15-0.20 EUR per ton of cement. For an OK mill grinding a similar product, the cost of wear parts depends on the maintenance procedures, i.e. whether hardfacing is applied.
