The first six-roller Loesche mill for grinding cement raw material

Conclusion
The successful commissioning of the first six-roller Loesche mills has justified the selected development concept, in which the grinding capacities of Loesche mills were boosted by increasing the number of rollers rather than the roller size/mass. The use of roller modules tested in practice
in four-roller mills made it possible to rule out potential development risk to dynamically loaded components. The modules so far installed in the largest six-roller Loesche mills are only medium-sized. Other module sizes, right through to the largest from the LM 63.4, are available and have been in use for years in the comminution of cement raw material. This means that further increases in performance can also be realised in the future insofar as these are demanded by the industry.
