The cement roller press, also known as roller press in cement plant, high pressure grinding roll (HPGR), is a kind of cement equipment for brittle materials, apply for grinding cement clinker, cement raw material, gypsum, coal, quartz sand, iron ore, blast furnace slag, and other materials.. The cement roller press is generally applied to the cement …
grinding of raw materials. The grinding efficiency of the vertical roller mill combined with an ability to dry, grind and classify within a single unit gives the vertical roller mill a decided advantage over a ball mill system. However, despite these benefits, applications of the vertical roller mill for cement grinding are less prevalent.
Working Principle. The working principle of vertical mill is as follows: the material is fed into the mill through the inlet on the top center of the mill and falls on the grinding plate, and the grinding rollers which are driven by the rotation of …
This paper deals in first place with roller mills for raw material processing. For grinding coal, slag, cement, etc., adaptations to mills and systems have to be made. 2.
