Grinding mill process design SAG ball rod and pebble mills in sizes ranging from kWs up to 30 MW Our product range also includes a number of unique solutions including the world’s largest acidresistant grinding mills which can operate with extremely corrosive slurry

A Total Apparent Volumetric Charge Filling – including balls and excess slurry on top of the ball charge plus the interstitial voids in between the balls – expressed as a percentage of the net internal mill volume inside liners B Overflow Discharge Mills operating at low ball fillings – slurry may accumulate on top of the ball charge causing the Total Charge Filling Level to be

The Attritors design accounts for much of the difference conventional ball mills turn the entire drum or tank containing the media and the material while Attritors stir the media in a stationary tank with a shaft and attached arms or discs resulting in a more efficient use of energy for the milling process

Ball milling technique using mechanical alloying and mechanical milling approaches were proposed to the word wide in the 8th decade of the last century for preparing a wide spectrum of powder materials and their alloys In fact ball milling process is not new and dates back to more than 150 years It has been used in size comminutions of ore mineral dressing preparing talc powders and many
