Ball Mill Enviado por Humbulani Ball mills are usually the largest consumers of energy within a mineral concentrator. Comminution is responsible for 50% of the total mineral processing cost. An innovative tool which can deliver information about inmill dynamics has been developed by Magotteaux.
Classification: The ball mills can be classified according to the shape of mill (cylindrical or cylindroconical), the methods of discharging the product (overflow discharge, or gate/diaphragm discharge mill), discharge rate ( high discharge mill and low discharge mill), and whether operated dry or wet.
Speed reducer output speed: r/min. Sealed air volume: m3/min. Size of primary air inlet (inner wall:) 1828×786mm. Normal lubricating oil temperature of reducer: 45℃ ~ 55℃. f 5. The Composition of The Coal Mill. HP bowl coal mill is mainly composed of the following.
Tumbling mills consist of a cylindrical shell slowly turning about a horizontal axis and filled to about onehalf its volume with a solid grinding medium. The grinding medium is balls of metal for ball mill. Large ball mill shells might be 10 ft in dia and 14 ft long. The balls are 1 to 5 inches dia. The load of the balls in ball mill is ...

Find out the critical speed of ball mill by using the following data: Diameter of the ball mill is 450mm and Diameter of the ball is 25 mm. 2. Calculate the operating speed of the ball mill from the given data below Diameter of the ball mill is 800 mm and Diameter of the ball is 60 mm. if critical speed is 40% less than the operating speed.
Regardless of mill length, the larger diameter mill provides a greater weight of balls per unit of mill weight. and gives more capacity per unit of power. Colored line indicates hphr/ton required to grind a hard ore from 1/2″. to 65% minus 200 mesh; closed circuit, wet grinding.

over the roof of the mill due to centrifugal action. The critical speed (rpm) is given by: nc = /√d. Where "d" is the internal diameter in meters. Ball mills are normally operated at around 75% of critical. speed, so a mill with diameter 5 meters will turn at around. 14 rpm. ffDESIGN CRITERIA FOR BALL MILL.

From a control point of view, a ball mill grinding circuit represents an interconnected multivariable system with strong interactions among process variables. A typical structure of a closedloop circuit for wet grinding consists of a ball mill, sump and classifier [10, 13, 33, 39] and it is schematically shown in Fig. 4. Fig. 4
d = (F80)^ [ Wi / (Nc D^)]^. where d is the makeup ball size in mm, F80 is feed size in m, is ore density (specific gravity) in t/m, Wi is. metric Bond work index for ball milling, N is mill rotation speed in rev/min; Nc is rotation speed as % of. critical, and D is the mill diameter in US feet. fYou'll get different answers from ...
