This is because at an AR of about 1.4, there is more clinker liquid at a lower temperature and combinability is optimised. (Minor constituents such as MgO can alter this optimum AR). The intrinsic reactivity of the raw materials - some types of silica, for example, will react more easily than will others.
typically generates ~ 25 kcal of heat per kg cement ground o Mill temperature could rise to 140 ˚C and causes gypsum to dehydrate & produces "false set" in cement, as well as "media coating" which impairs grinding efficiency o typically, ~ 0.8 m³ of cooling air is required to remove the heat Energy consideration in cement grinding
store and conveyed to the cement mill reception silos. Occasionally clinker is despatched directly for processing at other cement works and it may also be imported to the site.

Optimum mill operation depends on specific plant conditions and constraints, including clinker temperature, availability of hot gas, climatic conditions, quality of the feed materials (clinker composition, amount of additive materials such as gypsum, limestone, slag and their water content), legislative requirements, and storage time in the ...
a clinker. The clinker is discharged onto a traveling grate called a clinker cooler (Figure 1). Air from below the grates flows up through an 8 to 10 in. layer of clinker, cooling the clinker as it progresses through the cooler. Once the clinker has been cooled, it is transported to storage or directly to grinding mills.
The clinker content of the three kinds of cement is small, and the secondary hydration reaction is slow, while their later strength exceeds the ordinary Portland cement of the same grade. Sensitive to temperature and humidity, suitable for high-temperature curing.

o only < 2 - 5% of energy input is theoretically required to fracture particles; the bulk of the input energy ends up largely as heat & typically generates ~ 25 kcal of heat per kg cement ground o mill temperature could rise to 140 ˚c and causes gypsum to dehydrate & produces "false set" in cement, as well as "media coating" which impairs …
A 1.5 mio t/a cement plant is having a closed circuit ball mill for cement grinding: The mill has been operating with satisfactory performance in-terms of system availability and output, however power consumption was on higher side. 3.1 System Description Mill Rated capacity 150 t/h OPC at 2800 blaine I chamber liners
The invention relates to a clinker composition characterised in that it comprises: between 30 and 70 weight per cent of alite (C3S), between 10 and 40 weight per cent of belite (C2S), between 5 and 15 weight per cent of calcium sulfoaluminate (C4A3S), and between 1 and 7 per cent of ferrite (C4AF), the remainder consisting of anhydrite (CS) and/or lime (C3A).
The control of cement grinding/mixing process in an industrial mill regarding SO3 content has been effectively simulated taking into account all its fundamental sides and particularities.
The Chinese company Sinoma/CBMI was assigned to build a turnkey cement mill with a capacity of 3,600 tons of clinker per day – a significant project in Benin. Siemens supplied all the hardware and software engineering, from the integration of PCS 7 with CEMAT to data archiving and monitoring services.
Average clinker particle size A coarse clinker bed has less resistance than a bed composed of fine particles Clinker temperature (increase) An increase in clinker temperature increases the cooling air volume which increases bed resistance. Optimum clinker bed depth should allow free passage of air through it.

The rotary kiln is the heart of a cement manufacturing plant. Cement kilns have all chemical ingredients. These. ingredients are at a broad range of gas temperatures from 100° to 1650°C. The emissions contain: High concentrations of alkaline solids, including sodium and potassium oxides; High concentrations of freshly created Calcium Oxide.
clinker produced by a kiln controlled by Expert Optimizer. The control strategy is able to make optimum use of the available mill capacity and improve the production rate. • Reduced consumption of grinding media. As a result of the softer clinker produced in kilns controlled by Expert Optimizer the consumption of grinding media is reduced.
Cement manufacturing has several opportunities for WHR, specifically in the process step where the clinker material is produced. For clinker production, a mixture of clay, limestone, and sand is heated to temperatures near 1500°C. The kiln and clinker cooler have hot exhaust streams where waste heat could be recovered.
