Horizontal ball mill slakers typically operate between 75 o C and 85 o C Because the temperature is not measured in the slaking zone it is difficult to maximize the operating temperature to minimize chemical consumption An alternate version of the horizontal ball mill slaker is vertical ball mill slaker which is a vertical stirred ball mill .
A ball mill also known as pebble mill or tumbling mill is a milling machine that consists of a hallow cylinder containing balls; mounted on a metallic frame such that it can be rotated along its longitudinal axis The balls which could be of different diameter occupy 30 -50% of the mill volume and its size depends on the feed and mill size

involve grinding) With Lloyd's ball milling book having sold over 2000 copies, there are probably over 1000 home built ball mills operating in just America alone This article borrows from Lloyd's research, which was obtained from the commercial ball milling industry, and explains some of the key design criteria for making your own ball mill
Volume Load - thecementgrindingoffice 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)
For overflow ball mills, the charge should not exceed 45% of the mill volume For grate discharge mills, the charge should occupy about 50% of the mill volume Bond developed a relationship that can be used to determine the percent charge by volume as a function of the vertical height above the charge, He, and the radius of the mill, R, ie.
Rod mills are very similar to ball mills, except they use long rods for grinding media The rods grind the ore by tumbling within the the mill, similar to the grinding balls in a ball mill To prevent the conditions leading to rod charge tangling, the length to diameter ratio is maintained at 14 to 16
