Re: Cement milling. NO x and kiln torque are both good indicators of the temperature in the burning zone of the kiln. This is key to ensuring stable operation and good combination of the clinker. Kiln inlet oxygen is a good indicator of the combustion conditions in the kiln where a small excess of oxygen is necessary to ensure burning in oxidising conditions.
• Empty heights of both the chambers measured to calculate the ball charge, % filling and estimate the power consumption at mill shaft. Based on the empty height measurements, charging of grinding media in Chambers I & II calculated as equivalent to degree of .
Calculation of the power draw of dry multi-compartment ball mills 225 The mill load that is the volume of charge in the mill is the principal determinant of power draw. Estimation of the ball load that is mixed with the cement charge is difficult and can be highly erroneous. So direct measurement must be taken for calculation of mill load.
Before the mill motor is started, the grinding rollers are lifted hydraulically from the grinding track. The mill can then be started not only empty, but also filled, at low starting torque. An adjustable buffer prevents the grinding parts from coming into metal contact when the mill is empty or loaded.
