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.
2004 The 50th Loesche mill with 2+2 technology for grinding cement and granulated blast furnace slag was sold worldwide. 2005 The first mill with 3+3 technology, an LM 56.3+3, …
Ball mill is suitable for grinding all kinds of ore and other materials, is widely used in mineral processing, building materials and chemical industries, can be divided into dry and wet grinding two ways. According to the different way of ore discharge, it can be divided into two types: lattice type and overflow type.
