consumption and fan power consumption. Air leakage occurred in kiln and pre-heater increases fuel consumption in order for heating leaked cold air up to process temperature. However, air leakage in EP and raw mill does not normally increase fuel consumption, but it increases required power of fan motor.

mill is the energy consumption. The power supplied to the mill is used primarily to lift the load (medium and charge). Additional power is required to keep the mill rotating. 8.1.3 Power drawn by ball, semi-autogenous and autogenous mills A simplified picture of the mill load is shown in Figure 8.3 Ad this can be used to establish the essential
In this study, the first and second law analysis of a raw mill is performed and certain measures are implemented in an existing raw mill in a cement factory in order to reduce the amount of energy consumption in grinding process. The first and second law efficiencies of the raw mill are determined to be 61.5% and 16.4%, respectively.

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
mill consumes about 14 15 kWh/ ton of raw mix whereas the VRM motor uses 7 8 kWh/ ton. On an overall basis, VRM consumes about 20 % meal, cement and minerals, whereas Cemax Mill is mainly for cement grinding. The mill can be used for pre-grinding and finish grinding. This mill- significantly reduces power consumption.
Power Consumption in Cement Manufacturing Plant: The cement industry, as a traditional high power consumption industry, power consumption in the cement grinding process takes a large ratio in the whole production, electric power consumption is about 60%-70% of the total consumption.
The power ingesting of a grinding process is 50-60% in the cement production power consumption. The Vertical Roller Mill (VRM) reduces the power consumption for cement grinding approximately 30-40% associated with other grinding mills. The process variables in cement grinding process using VRM are strongly nonlinear and having large time

The first and second law efficiencies of the raw mill are determined to be 61.5% and 16.4%, respectively.
The mill differential pressure or the mill motor power consumption is an indication of how much material inside the mill. Normally the feed rate is controlled by the mill motor power consumption through an automatic loop. Vibrations A constant and acceptable level of vibrations is important.
The OK 54-6 raw mill with 8,700 kW installed power, follows FLSmidth’s modular mill design where rollers from the OK 39-4 mill are applied to a larger diameter table. Lower power consumption Compared with other cement grinding VRMs, the OK mill consistently operates with lower airflow and the lowest power consumption.
