Aug 25, 2011· Cement producers have faced a significant rise in energy costs with the introduction of dry-process kilns, with a record average consumption of 100-200 kWh per ton of cement, according to the 2009 Cement Plant Operations Handbook. This complex challenge, coupled with rising fuel and energy …
In the conventional process of cement production, 30–80 kWh/t specific energy is consumed in cement grinding which equals 30% of the total energy consumption. Furthermore, approximately 60–70% of the total electrical energy used in a cement plant is utilized for the grinding …
Total energy consumption in a typical dry process cement plant is 75-80 per cent fuel (thermal energy) and 20-25 per cent electricity (electrical energy) 99 per cent of the fuel consumption is used for clinker burning or pyro-processing. Hence, pyro-processing has highest scope about 5 - 40 per cent for improvements in terms of energy efficiency.

A mill is a device that breaks solid materials into smaller pieces by grinding, crushing, or cutting. Such comminution is an important unit operation in many processes.There are many different types of mills and many types of materials processed in them. Historically mills were powered by hand (e.g., via a hand crank), working animal (e.g., horse mill), wind or water ().
For more even grinding, some machines are also equipped with floating heads that will follow the contour of the floor and adjustable rear wheels to keep the grinding discs level. Many manufacturers offer a choice of power options, including electric, gasoline and propane. Most machines are equipped with vacuum ports for dust-free dry grinding.
A cement mill (or finish mill in North American usage) is the equipment used to grind the hard, nodular clinker from the cement kiln into the fine grey powder that is cement.Most cement is currently ground in ball mills and also vertical roller mills which are more effective than ball mills.
Make energy consumption as the first goal is a leap of management thoughts: 1. To reduce electricity consumption can make allowances for grind production increasing. 2. Height consistent of power consumption reduction and cement quality. 3. Power consumption reduction can be helpful for the operation rate. 4.
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 basic parameters used in ball mill design (power calculations), rod mill or any tumbling mill sizing are; material to be ground, characteristics, Bond Work Index, bulk density, specific density, desired mill tonnage capacity DTPH, operating % solids or pulp density, feed size as F80 and maximum 'chunk size', product size as P80 and maximum and finally the type of circuit open/closed ...
