The classifier delivered 33 T. of sand per hour. The total ball-mill feed was therefore 40.37 T. per hr. or 550 per cent, of the original feed. Two Stage Grinding. The object of these tests was to determine the capacity of ball-mills when crushing in two stages. The conditions of the test were as follows: First Stage of Ball Milling

Particle size reduction of materials in a ball mill with the presence of metallic balls or other media dates back to the late 1800's. The basic construction of a ball mill is a cylindrical container with journals at its axis. The cylinder is filled with grinding media (ceramic or metallic balls or rods), the product to be ground is added and ...

Within comminution circuits, High Pressure Grinding Rolls (HPGR) are increasingly replacing conventional SAG, rod and ball mills for hard rock reduction – owing to their substantially lower energy consumption and potential for significant total cost of ownership reduction. Not only do they require as much as 40% less energy than traditional …

Hard ore Work Index 16 = 100,000/65,000 = 1.54 kwh/t. For the purposes of this example, we will hypothesize that the the crushing index of the hard ore with the increased energy input of 1.54 kw/t reduces the ball mill feed size to 6,500 micrometers. As a result, the mill output will increase with this reduced size to approximately 77,000 tons ...
