Loesche Mills for Cement Raw Material
1934 Loesche mills are increasingly also used worldwide for limestone and cement raw material. 1937 400 Loesche mills have already been sold for coal, phosphate and cement raw material. 1939 The largest Loesche mill at this time is an LM 16 with two steel spring-loaded rollers, a grinding track diameter of 1,600 mm and product throughput of 22 t/h.
Vertical Roller Mills - FL
It features a patented roller and table design and concrete mill stands instead of traditional, heavy steel structures. The OKTM Mill's flexible design makes it possible to operate it with a number of rollers out of service while still reaching 60 to 70 percent of the normal operation output, minimising production losses.
