D diameter of ball mill in m D 450 mm 045 m R 0225 m

Unit Operations-I 2.26 Size Reduction of Solids Example 2.6 : What rotational speed, in revolutions per minute, would you recommend for a ball mill 1200 mm in diameter charged with 75 mm balls ? Solution : The critical speed of ball mill is given by N c = 1 2 π g R r, in r.p.s. where g = 9.81 m/s 2 R = radius of the ball mill Diameter of ball mill = 1200 mm ∴ R = 1200 / 2 = 600 mm = 0


Ball Mill an overview ScienceDirect Topics

Ball mills tumble iron or steel balls with the ore. The balls are initially 5–10 cm diameter but gradually wear away as grinding of the ore proceeds. The feed to ball mills (dry basis) is typically 75 vol.-% ore and 25% steel. The ball mill is operated in closed circuit with a particle-size measurement device and size-control cyclones.


Ball Mill Ft Diameter

Ball Mill Ft Diameter. Apr 01, 1988nbsp018332The data includes mill diameters ranging from 0.4 to 5.5 m 1.3 to 15 ft and lengths ranging from 0.4 to 9.8 m 1.3 to 32 ft with ball sizes ranging from 38.1 to 76.2 mm 1.5 to 3.0 inches. The development of this correlation was based on consideration of the tur bulence level in a mill and its influence on the extent of dispersion back
