• avoidance of pneumatic transport systems ... Correct timing on the maintenance of a first chamber cement mill lining and the successful implementation of an expert system on a cement mill both offer benefits in terms of power consumption (see case studies panel). Accurate process measurements are also key to energy saving opportunities.
Bulk shipments of dry cement were among the first commodities to be hauled in covered hopper cars. Because of their sturdiness and ease of use, they are still the rail car of choice for cement transport today. Typically shipped in free flowing, dry form, 110 tons of cement can be conveniently piped directly into a hopper car.
The cement is taken over by a transport relay and stored in the cement silos, the coarse part returning to the mill for a new crushing. The cement is then taken up and transported to the silos, either with a conveyor belt and elevator or with a system of pneumatic gutters and elevators [ 39 ].

After the raw materials are calcined to clinker, the temperature begins to decrease. Finally, the high-temperature clinker discharged from the rotary kiln is cooled by the cement clinker cooler to the temperature that the downstream transport, storage, and cement mill can bear. Meanwhile, the heat of the high-temperature clinker is recovered by the cooler to improve the thermal …
Cement heated to 1,650 – 1,830°F. A high loss on ignition can indicate pre-hydration and carbonation, which may be caused by improper and prolonged storage or adulteration during transport or transfer Cement treated with hydrochloric acid – a measure of "non-cementing" materials largely arising from gypsum impurities
Coal Mill(Contd.) • The raw is then fed to the coal mill VRM via weigh feeder, drag chain and screw conveyer. • Coal Mill is an important integral part of cement plant. Here large size of approx size 600mm, is ground fine to the size of 90 micron. Coal from coal mill is used to feed kiln and calciner.
Where the alkali occurs in the cement can affect this, but to get a first approximation, we need to track the equivalent alkali content. If a change is noted in the mill certificate, air-entraining agent dosages may need adjustment. Above 0.60%, alkali changes of 0.1% can be significant.

This is done by a mixture of both air-cooling and water-cooling, including spraying water inside the mill. Cement milling and gypsum dehydration Because the cement gets hot due to the heat generated by grinding, gypsum can be partly dehydrated, forming hemihydrate, or plaster of Paris - 2CaSO 4 .H 2 O.
The belt conveyor is used to mix and transport the cement clinker, gypsum, and mixture in a certain proportion. The cement roller press and cement mill are used to grind the cement raw material to the required particle size and packaging. There are two types of cement mill including a ball mill and vertical cement mill.
