The mill has its name from the way of transporting the raw material. The ground material is swept out by the mill exhaust gases. This requires a high gas flow rate within the mill. Therefore its inlet device is designed to meet this requirement. The raw material is fed into the gas stream entering the mill.

A mediumsized dry process roller mill. 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 raw milling stage of the process effectively defines the chemistry (and therefore physical properties) of the finished ...

The cement rotary kiln. When operating the vertical roller mill, the operator must control the inlet and outlet air valves to make the air volume of the system in a balanced state, so as not to affect the air pressure at the back end of the rotary kiln.

In cement plants, generally false air intrudes in the kiln section through the kiln outlet, inlet seal, TAD slide gate, inspection doors and flap box. Similarly, in mill section false air intrudes through rotary feeder at mill inlet, mill body, mill door, flaps, expansion joints, holes of ducts and tie rod entry point.

Typical clinker nodules. Alite is the characteristic constituent of Portland cement. Typically, a peak temperature of °C is required to complete the reaction. The partial melting causes the material to aggregate into lumps or nodules, typically of diameter 110 mm. This is called clinker.

mill has to be calculated through a heat balance. The maximum admissible mill inlet temperature is < 450 [C]. Gas speeds: The mill has to be sized to meet the required speed ranges: e Nozzle ring: = 30 [m/s], higher speeds can be adjusted by covering nozzles e Mill casing: 7 [m/s] for vertical transport
