    Figure 8.4 The effect of mill speed on the power drawn by a rotating mill. The liner profile and the stickiness of the pulp in the mill can have a significant effect on the actual critical velocity. Mills usually operate in the range 65 82% of critical but values as high as 90% are sometimes used.

    Feb 12 2017· As rocks is feed into the mill they are crushed (pinched) by the weight of its 3.5 x 16 rods at one end while the smaller particles migrate towards the discharge end and get slightly abraded (as in a Ball Mill) on the way there.

  • The operating principle of the ball mill energosteel

    The operating principle of the ball mill consists of following steps. In a continuously operating ball mill feed material fed through the central hole one of the caps into the drum and moves therealong being exposed by grinding media. The material grinding occurs during impact falling grinding balls and abrasion the particles between the balls.

  • Effect of Grinding Media on Milling

    Effect of Balls Hardness on Rate of Grinding Tests by Coghill and Devaney show that the hardness of the balls has some effect upon the rate of grinding in mill. These results are plotted in Fig. 6.8a and it is seen that both for dolomite and chert there is an increase in the rate of grinding with increasing hardness of ball.

    Ball Mills. The ore from the crushing section is delivered to the fine ore bin placed at the head of the grinding section from which it is fed together with water to one or more grinding units consisting of a ball mill or rod mill in circuit with a classifier. One such unit with a conical ball mill is shown in Fig.

  • Optimum choice of the make up ball sizes for maximum

    For the same amount of ball charge the number of balls in the mill decreases as the ball size increases. Thus the S values are lower for larger balls. However larger balls are capable of breaking large particles; therefore the size at which the S value becomes maximum x m increases as the ball

  • Ball Mill an overview ScienceDirect Topics

    Ball mills give a controlled final grind and produce flotation feed of a uniform size. Ball mills tumble iron or steel balls with the ore. The balls are initially 510 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.
