Technical cost is also an important factor that affects the price of vertical mills.
Cement Milling. In a horizontal ball mill, the clinker is ground by different-size steel balls while it works its way through the horizontal mill's chambers, with gypsum being added to extend cement setting times. In a vertical cement mill, clinker is ground through the pressure exerted by four rollers, which roll over a turning milling table. i.

Vertical roller mills are developed to work as air-swept grinding mills. Roller mills are operated with throughput capacities of more than 300 t/h of cement raw mix (Loesche mill, Polysius® double roller mill, Pfeiffer® MPS mill). Loesche roller mill and Polysius® roller mills are widely applied in cement raw material grinding.
A raw mill is the equipment used to grind raw materials into "rawmix" during the manufacture of cement. Rawmix is then fed to a cement kiln, which transforms it into clinker, which is then ground to make cement in the cement mill.The raw milling stage of the process effectively defines the chemistry (and therefore physical properties) of the finished cement, and has a …
