Cement plants normally have sufficient silo space for 1–20 weeks production, depending upon local demand cycles. The cement is delivered to end-users either in bags or as bulk powder blown from a pressure vehicle into the customer''s silo. In industrial countries, 80% or more of cement is delivered in bulk. Our raw mill has been widely used in
Vertical roller mills (vrms) have become the equipment of choice for raw and solid fuel grinding in cement factories. increasingly modern cement plants also use vrms for cement grinding. however, opportunities for the optimisation of vrms are less obvious than with ball mills as all processes of grinding, drying, classification and regrinding take place within the body of the mill.

The cement raw material mixtures are ground, dried, and classified in the Pfeiffer vertical roller mill. For drying the material, hot gases are directed into the mill. Product fineness can be adjusted within a wide range (0.063 to 0.2 mm). The ground and dried product is separated from the process gas in a cyclone collecting system which is followed by the mill fan. Downstream of the mill fan

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
Raw meal homogenization is the most important process link of the four, accounting for 40% of the homogenization task. It is an important factor to support the balanced and stable working performance of preheaters and kilns, and plays an important role in improving the output and quality of cement clinker.
