Ness ranging from 1 to 5 while a jet mill can grind materials with mohs hardness as high as 10 high hardness materials become very abrasive therefore they are not suitable for highspeed hammer mills in a typical jet mill grinding action is caused mainly by particleparticle collisions so wear to the mill’s internals is less of an
Safe efficient and trouble free operation of your valmetal hammer mill requires that you and anyone else who will be operating or maintaining the hammer mill read and understand the safety operation maintenance and trouble shooting information contained in the rods turning at high speed 12 always keep hands and clothing clear of moving
The critical speed of ball mill is given by where r radius of ball mill r radius of ball for r 1000 mm and r 50 mm n c 307 rpm but the mill is operated at a speed of 15 rpm therefore the mill is operated at 100 x 15307 4886 of critical
The distance between hammer and screen should be 05 inches ≈ 12 to 14 mm for size reduction of cereal grains the velocity or tip speed of the hammers is critical for proper size reduction tip speed is calculated by multiplying the rotational speed of the drive source shaft rpm by the circumference of the hammer tip arc formula 1
