The rotation of the kiln lifts the feed up the side of the kiln, and the energy required to maintain its centre of gravity above the lowest (6 o'clock) point is the main component (8090%) of the energy consumed. In the case of kilns containing curtain chains, these also produce an eccentric load. Rotary kilns have always had variable speed drives.
· Portland cement is produced by one of the most energyintensive industrial processes. Energy consumption in the manufacture of Portland cement is approximately 110–120 kWh ton−1. The cement rotary kiln is the crucial equipment used for cement production. Approximately 10–15% of the energy consumed in production of the cement clinker is directly dissipated into the atmosphere .
· Typical cement plant power costs can range from EUR39 to EUR170/MWh. Mill designs. The most important first step in controlling energy consumption is to be aware of the relative importance of the process areas where most energy is consumed. Figure 2 shows a typical breakdown of electrical energy consumption at a cement plant.
The analysis of cement kiln energyefficiency opportunities is divided into technologies and measures that are applicable to all kilns, those that are only applicable to rotary kilns, those that are only applicable to vertical shaft kilns, and product and feedstock changes that will reduce energy consumption for clinker making.

Rotary kilns represent the largest energy consumer and carbon dioxide emission source of the cement/concrete industry. The cover diagram shows a thermal image of an operating kiln. The high temperature of the kiln surface (300°F to 400°F) accounts for about a 5% energy efficiency loss. The diagram on the cover depicts a kiln that has lost ...
Rotary kiln can be divided into cement kiln, metallurgical chemical kiln and lime kiln according to different processing materials. It has been successfully applied to the roasting of molecular sieve alysts and alytic cracking alysts, oil sands, fly ash, alumina, chrome ore, chrome ore powder, cement clinker, activated lime and light burnt dolomite.
· Modern lime kilns take 6–8 million BTUs per ton, so that's 12 40 per ton energy costs. BTUs can be easily converted to MWh, and 6–8 million BTUs turns into to MWh.
Explore design concept of rotary dryer for processing the phosphogypsum. Abstract The cement industry nowadays is giving thrust to replace and reduce fossil fuelbased energy through recovery of waste heat, utilization of wastes (Alternative fuels) and adoption of renewable energy sources like wind energy, solar PV systems etc.
The energy consumption accounts for 1/21/3 of the cost of cement, which is higher than that of the vertical kiln and dry rotary kiln. Because of the high heat consumption, high energy consumption, large water consumption, and water resources consumption in wet production, wet cement production has been listed as a type of kiln that restricts the elimination of cement.
