Basic Ball Mill Grinding Circuit - how to grind black sand into a powder
Therefore, the ball mill length shall be designed appropriately, so is the diameter. In this way, the ball mill efficiency is improved with an appropriate crushing and energy consumption. Ball mills of different length and diameter The theoretical ratio of length to diameter is between 1.09 and 1.5.eighty percent of six millimeters or finer for hard rocker eighty percent of twenty-five millimeters or finer for fragile rocks (Larger feed sizes can be tolerated depending on the requirements). The ratio of machine length to the cylinder diameter of cylindrical type ball mills range from one to three through three to one.
