The Critical Speed is used for the determination of ball mill ideal operating speed. But for comparison rod mills would operate between 50 to 95 of the critical speed. The faster the mill speed the greater the wear on the rods and liners.
SAG mills of comparable size but containing say 10 ball charge in addition to the rocks normally operate between 70 and 75 of the critical speed. Dry Aerofall mills are run at about 85 of the critical speed. The breakage of particles depends on the speed of rotation.
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 30.7 rpm. But the mill is operated at a speed of 15 rpm. Therefore the mill is operated at 100 x 1530.7 48.86 of critical speed. Get Price.
The critical speed formula of ball mill 4229 is a horizontal cylindrical equipment which is used in grinding under critical speed. It is expressed by the formula NC 4229 VDD. The critical speed is m and the mill with diameter of 5 m rotates when reading more.
The point where the mill becomes a centrifuge is called the Critical Speed and ball mills usually operate at 65 to 75 of the critical speed. Ball Mills are generally used to grind material 14 inch and finer down to the particle size of 20 to 75 microns.
