— To produce powdered cement, the nodules of clinker are ground to the consistency of powder. Grinding of clinker, together with additions of approximately 5 percent gypsum to control the setting properties of the cement can be done in ball mills, ball mills in combination with roller presses, roller mills, or roller presses.
would be a length of 13.5 m and a diameter of 2.5 m, with a speed of approximately 20 revolutions per minute. Such a mill would normally have a load of approximately 90 tons of grinding media, graduated from 90 mm to 60 mm in the first chamber, 50 mm to 15 mm in the second chamber and 15 mm down in the final chamber.
Cement plants must endure freezing cold and sweltering heat - sometimes within mere months of each other. Despite such extreme conditions, machinery and equipment used at cement plants must operate effectively, efficiently, safely, and smoothly. Making sure that your cement equipment is properly lubricated is a good start.
When cement clinkers are ground inside a ball mill, a significant amount of friction between balls is converted into heat, which can negatively impact clinker properties and complicate further processing.

A key enabler of lowering water spray is the use of an appropriate grinding aid product designed for use in VRMs. Using two cement industry case studies, GCP explains
VRMs tend to use considerably more water than ball mills; thus cement produced in VRMs exhibits, on average, higher prehydration levels than cement produced in ball mills. GCP Applied Technologies recently conducted a survey of 181 different cements produced in both ball mills and VRMs. 2. The survey found that 48% of the VRM-produced cements …

water vaporises inside the mill. Thus, a reduction in water spray can result in fuel savings as well as water savings. A further consideration is the negative effect of VRM water spray on cement quality. High levels of water spray cause prehydration of the cement, which can reduce strength, extend set times and interfere with the effect of chemical
