This data-file captures cement costs, based on inputs, capex and energy economics. A typical cement plant requires a cement price of $130/ton for a 10% IRR, on capex costs of $200/Tpa, energy intensity of 1,000 kWh/ton and CO2 intensity of 0.9 tons/ton. Cement costs can be stress tested in the data-file.
However, in general, maintenance costs can be expected to represent a significant portion of the overall operating costs of a bauxite calcination plant. Tips for Reducing Maintenance Costs. There are a number of things that can be done to reduce the cost of maintaining bauxite calcination crushers. These include:

Cement acts as the binder between aggregates (fine and coarse rocks) in the formation of concrete. While cement makes up only a small percentage of the mix (approximately 12 percent by volume), it is almost exclusively responsible for the resulting CO 2 emissions. In the cement-manufacturing process, raw materials are heated to high …
Specific maintenance costs were assumed to be 7 €/MWh (yearly maintenance costs around 4% of the overall capital cost), 80% plant capacity factor and a cost of coal of 1.5 €/GJ. Fixed cost has been taken as 1% of the total capital requirement.

Since CSP substitutes for coal to supply part of the calcination energy, standard coal consumption rate of co-driven case decreases by 6.9 g/kW h compared with coal-driven case. The baseline plant has an efficiency of 45%, while the thermal efficiencies for coal-driven case and co-driven case are 35.65% and 35.37%, respectively.
Important control variables are heating rate, air addition rate and final calcination temperature. To obtain the calcined coke properties required by the carbon and graphite industries, the coke must be subjected to temperatures of 1150-1350 Deg C or higher to achieve density and conductivity.
In case of a CSP plant without thermal energy storage for the operation of the solar calciner, the calcination step is limited to the sunny hours (≈8h/day). Since the cement plant operates 24 h/day, two particle storage vessels are needed to continuously clean the flue gas of the cement plant.
