36’’ = 914 mm
41’’ = 1041 mm
48’’ = 1219 mm
54’’ = 1371 mm
and ratios 54/5 – 65/4 – 76/5 – 94/5 104/5 – 94/7 and 100/7
Our maximum capacity is: centre distance = 1600.
CMD has more than 600 large-scale worm gears operating in vertical coal mills in leading manufacturers worldwide.
These gears are used in electric power stations and cement plants. The milling process involves several pendulous rollers with pressure applied to the plate. These are directly controlled by the worm gear.
