① Ceramic Ball Mill: It prevents iron pollution and is especially suitable for grinding glass and ceramics. Ceramic mill balls are white aluminum balls with a diameter within 0.5-120 mm. ② Rod Mill: Same as ball mills, except for the use of steel rods as grinding media. The maximum feed size is 50 mm. The output size is 4-35 mesh.
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 ...
The supply of cheaper iron aided a number of industries, such as those making nails, hinges, wire, and other hardware items. The development of machine tools allowed better working of iron, leading to increased use in the rapidly growing machinery and engine industries. Iron was used in agricultural machines, making farm labor more effective.
