• Concrete • Electrical • Structural steel • Instrumentation. • Architectural Indirect Costs. Indirect costs can fall within a range of 40 to 60% of the direct costs, and include: • Construction indirects • Startup and commissioning • Construction equipment • Freight • Spare parts/first fill • Taxes/duties

The cement industry is one of the most intensive energy consumers in the industrial sectors. The energy consumption represents 40% to 60% of production cost. Additionally, the cement industry contributes around 5% to 8% of all man-made CO 2 emissions. Physiochemical and thermochemical reactions involved in cement kilns are still not well understood because of their complexity.

In electric drives the driving equipment is an electric motor. Selection of particular type of motor driving an m/c is the matching of speed-torque characteristics of the driven unit and that of the motor. · Different types of loads exhibit different speed torque characteristics.

Depending on the application, carbon and silicon content are adjusted to the desired levels, which may be anywhere from 2–3.5% and 1–3%, respectively. Other elements are then added to the melt before the final form is produced by casting. Iron is more often melted in electric induction furnaces or electric arc furnaces.

Some applications of cycloconverters are: • Cement mill drives • Ship propulsion drives • Rolling mill drives • Scherbius drives • Ore grinding mills • Mi ne winders 1.Operation Principles: The following sections will describe the operation principles of the cycloconverter starting from

The type of drive chosen to run the industrial motor can add some positional awareness. An encoder can be added to the motor if the application requires it, and a drive can be specified to use the encoder feedback. This setup can provide servo-like speed as a result. 3. Is position control required for the application?
