Girth gears for cement mills | CEMEX | Czech Republic ...
The production process culminates in two ball mills. Each day, the 15-meter-long machines grind up to 5000 metric tons of clinker – the result is ready-to-use Portland cement. In each mill, two pinions and gear units transfer the force from two 2250-kilowatt asynchronous motors to a girth gear that is directly connected to the ball mill surface.
