Vertical roller mill
The vertical roller mill is a kind of grinding machine for cement, raw material, cement clinker, slag and coal slag. It has the benefits of simple structure and low cost of manufacture and use. Vertical roller mills have many different forms, but they work basically the same. All of these forms come with a roller (or the equivalent of roller grinding parts), and roller along the track of the disc at the Altun et al.

A Technical and Economic Comparison of Ball Mill Limestone
ABSTRACT. Wet flue gas desulfurization (WFGD), using limestone with forced oxidation (LSFO), is a common Flue gas desulfurization (FGD) process where limestone reacts with SO 2 to produce gypsum (CaSO 4.2H 2 O). In South Africa, Eskom’s Kusile Power Station utilizes conventional wet ball milling to grind high-grade limestone of 80mm. The raw materials are mixed in a certain proportion and fed into a vertical roller mill (LOESCHE mill). The vertical roller mill grinds the marital to D 85 of 90µm. The ground product is calcined in a preheater to 850-900℃. After calcination, the materials enter to a rotary kiln and heated to 1450℃ to become clinker.Modeling and simulation of vertical roller mill using population

Cement grinding Vertical roller mills VS ball mills
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.30.0 Particle Size Diameter d50 [m] 40.0. 0.0.
