Vertical roller mill are suitable for huge capacity producing, widely used in grinding non-flammable and non-explosive materials under 9.3(the Moh's hardness), such as quartz, feldspar, calcite, talcum, barite, fluorite, iron ore, copper ore quartz, especially for slag, cement clinker, zircon sand, fly ash and carborundum, coal, etc.
A vertical roller mill has been installed in a Canadian cement plant for the pregrinding of Portland cement clinker. It is the first application of this type of technology in the Western Hemisphere. The process of selection of the technology and the development of the engineering project are described.
For most mill systems, manufacturers recommend the following raw material size: Fine clinker is more of an issue in vertical roller mills, since it can quickly slip under the rollers, leading to vibration and instability. As a general rule, there should be less than 25% of clinker that is below 1mm in size. ... Fine clinker is less of an issue ...
silica ratio and % C3S in clinker. The above relations as mentioned is computed for a specific raw materials use, keeping similar flux content. With the increase in C3S content in clinker, mix L.S.F. may touch 100 (even more) for a coal fired kiln — making mix harder to burn.But at the same time, reduced S.M. with C3S rise in clinker may help …
The common intergrinding of limestone and clinker in classical ball mills is there-fore producing a cement of very high surface. The higher the limestone content, the higher the negative impact of its surface on water demand and powder flowability.
