Sampling Samples must be representative of each filling nozzle For single filling size Take a minimum of 3 fill containers from each of the beginning middle and end of the filling run. The total number of samples must be not less than 10.## Ball mill - LinkedIn SlideShare

24/4/2015& 0183;& 32;Ball mill consist of a hollow cylindrical shell rotating about its axis. Axis of the shell horizontal or at small angle to the horizontal It is partially filled with balls made up of SteelStainless steel or rubber Inner surface of the shell is lined with abrasion resistant## Volume Load

The measurement of the ball charge volume load or filling degree is essential to maintain the absorbed power of the mill and consequently the mill production. The most common way to evaluate the filling degree is the measurement of the free height inside the mill vertical distance between the top of the charge and the lining in the mill axis .## Ball Mills - an overview ScienceDirect Topics

The degree of filling the mill with balls also influences productivity of the mill and milling efficiency. With excessive filling the rising balls collide with falling ones. Generally filling the mill by balls must not exceed 30–35% of its volume. Productivity of ball mills## Cement mill notebook - LinkedIn SlideShare

Example: Two compartment cement mill Diameter = 4.05 m Length = 12 m Filling degree = 196 tons at 30% filling degree Mill speed = 16.27 rpm C = 0.223 from the figure Then: K = 0.223 * 196 * 4.05 * 16.27 = 2.88 KW 8.2 Calculation of the Specific Consumption of## Page 1 Ball Milling Theory
