1. Introduction. World cement production is about billion tons in 2019 and cement plants consume about 2 percent of world electrical energy in the grinding process [1], [2].The total electrical energy that is consumed in cement companies is about 100 kWh per 1000 kg of cement, and twothird of this amount just consumes in raw material and cement mill units [3].

Average material height above the ball surface level (18 cm) and free height of the mill ( m) were measured to be used in mill powder load (holdup) calculation ahead of collecting the samples along the long axis of the mill at the crashstop condition. Mill filling was calculated to be 32% using the mentioned geometrical measurements.

A 10 MW cement mill, output 270 tonnes per hour. A cement mill (or finish mill in North American usage [1]) 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.

In cement mills, ventilation is a critical key for maintaining temperature and material transportation. However, relationships between operational variables and ventilation factors for an industrial cement ball mill were not addressed until today. This investigation is going to fill this gap based on a newly developed concept named "conscious laboratory (CL)". For constructing the CL, a ...
