Three Operating Guidelines to Teach You How to

Take the grid ball mill as an example. When the grinding ore (>0.15mm), the grinding concentration should be controlled between 75-85%; when the overflow ball mill is processing fine grinding products (0.10-0.074mm), the grinding concentration is generally controlled between 65-75%. Higher grinding concentration could make the surface of the
