Cement is typically made from limestone and clay or shale. These raw materials are extracted from the quarry crushed to a very fine powder and then blended in the correct proportions. This blended raw material is called the 'raw feed' or 'kiln feed' and is heated in a rotary kiln where it reaches a temperature of about 1400 C to 1500 C.
A rawmill 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. ... For this reason, the early cement industry used the "wet process", in which the raw materials...
clays, and shales used as raw materials for portland cement. Because a large fraction (approximately one third) of the mass of this primary material is lost as carbon dioxide (CO2) in the kiln, portland cement plants are located close to a calcareous raw material source whenever possible. Other elements
PENTA also prepared the mechanical general arrangement drawings for the raw mill feed bins, bin building and all raw material and clinker (mechanical) transport systems and raw meal and cement (pneumatic) transport systems plus the detailed mechanical engineering for all chutes, dedusting ducts and piping systems.
The raw mill considered in this study is located in a cement plant located in Sanliurfa, Turkey. The plant is a single chamber mill with mechanical circulation system which grinds a medium hard material at a capacity of about 160 tons/h.

Raw milling. The gas-swept vertical mill quickly became the raw mill of choice. Grinding energy was approximately 50 per cent of the ball mill and the drying capabilities allowed direct processing of materials of up to 20 per cent moisture content.[PDF]
(4) This type of mill can crush materials which are too large to be fed into the tube (ball) mill. (5) Ground materials are dried by the flue gas from the kiln. Fig.2 Schematic process flow of vertical roller mill for grinding of raw materials. Vertical roller mills are adopted in 20 cement plants (44 mills) in Japan.[PDF]

4 Due to the interaction of raw materials and kiln gases, rotary kiln systems have inherent SO2 removal efficiencies ranging between 40-99% of the sulfur input to the system. The literature suggests that 50-70% of the remaining SO2 will be removed from exhaust gases when passed through an in-line raw mill .
