These have been used for many years for the less exacting raw-milling process, but recently roller mills, in combination with high-efficiency separators, have been used for cement grinding. The grinding action employs much greater stress on the material than in a ball mill, and is therefore more efficient.
A first approximation of the chemical composition required for a particular cement is obtained by selective quarrying and control of the raw material fed to the crushing and grinding plant. Finer control is obtained by drawing material from two or more batches containing raw mixes of slightly different composition.
Raw materials that are used to produce clinker need to be ground in order to get high level of particles fineness. Similar with cement grinding aid, grinding process efficiency of cement raw materials will also affect raw mill output.
From the early 1900s, both for cement grinding and for grinding hard raw materials, whether by wet or dry process, the standard arrangement was a ball mill for preliminary grinding (to below 0.75 mm), followed by a tube mill for fine grinding.
Successful cement production starts with the raw materials and the methods needed to process it. Vertical mills grind the raw powder to the correct fineness before it is subsequently burned in the rotary kiln to produce clinker.
