Here, we mainly introduce development history of vertical grinding mill. Vertical roller mill is also called vertical grinding mill, roller mill and vertical roller mill. The first vertical mill was invented in the 1920s in Germany while the first vertical mill used for cement production appeared in 1935 in Germany.
The MPS mill also grinds, dries, calcines, and classifies gypsum without any problem, all in a single machine, for any fineness requested and considering individual requirements. The MPS vertical roller mill built to last, reliable and energyefficient is the optimum solution when it comes to performing several process steps in one unit.
I see that several have answered based on dry grinding, Vertical Roller Mill vs. conventional Ball Mill. If we instead focus on wet grinding, we should differentiate between stirred media grinding, which can be both vertical and horizontal, and tumbling mills with manufactured grinding bodies.
We are devoted to the ultra fine powder grinding mill. During the past decade, we have accumulated rich experience and have designed and launched the optimized and outstanding vertical roller mills for ultra fine powder. Among which, CLUM series ultrafine powder vertical roller mills are the key products.

The grinding process in ball mills and vertical roller mills differ fundamentally. In a ball mill the comminution takes place by impact and attrition. The comminution in the vertical roller mill takes place by exposing a bed of material to a pressure sufficiently high to cause fracture of the individual particles in the bed, although the ...
Vertical Roller Mill Working Principle. There are many different forms of vertical mill, but the working principle is basically the same. All these forms of vertical roller mill with the grinding roller (or the equivalent of grinding roller grinding parts), grinding roll along the horizontal circular motion on the disc, the vertical pressure exerted on the grinding roller through the outer ...
