Ball Mill

8.3.2.2 ball mills. the ball mill is a tumbling mill that uses steel balls as the grinding media. the length of the cylindrical shell is usually 1–1.5 times the shell diameter (figure 8.11). the feed can be dry, with less than 3% moisture to minimize ball coating, or slurry containing 20–40% water by.

Ball Mill Grinding Theory

Apr 28,   ball-mill power, 108 kw. in the first stage, 9.11 t. of minus 200-mesh material were produced per hour and 11.98 kw.-hr. were required for each ton of minus 200-mesh material produced. the classifier delivered 32 t. of sand per hour. the total feed to the mill was therefore 47.31 t. per hr. or 308 per cent, of the original.

Cement Grinding Vertical Roller Mills Versus Ball Mills

As less grinding energy is used in producing a cement of a required fineness in an ok mill and the retention time in the mill is shorter, the product will not be heated up as much as in a ball mill. this means that a lower degree of dehydration of the gypsum must be anticipated. this may not be a problem if the gypsum is.

Attrition Mills

Dec 13,   milling in an attrition mill (fig. 24) is effected by the stirring action of an agitator that has a vertical rotating shaft with horizontal arms. this motion causes a differential movement between the balls and the material being milled, thus providing a substantially higher degree of surface contact than is achieved in tumbler or vibratory mills.. fig. 24 attrition ball.
