  • Grinding Ball Gerdau Website

    Grinding Ball. Gerdau Grinding Ball products are produced in a facility designed specifically to manufacture high carbon, forged steel for application in the mineral processing and mining industries. Typical applications are copper, iron ore, gold, cement, nickel and phosphate. Grinding Balls are available in diameters ranging from 1" to 3.5". grinding temperature is dependent on its composition, heat treatment and form. Hardened tool steel, for example, can normally tolerate an arc-of-cut "hot spot" of 650º C without experiencing problems. But the same hot-spot temperature could cause an intricately shaped 52100-grade part to crack. Additionally, the amount of hard carbides

    STEEL. Steel Shot There are many sources for steel shot but all are not equal since much of the steel shot is used for shot peening. Make sure that the shot is designed as a grinding media or it could tear up the mill. Steel shot is one of the least expensive grinding medias with the benefit of high density and the availability of a wide range of sizes for small media.

  • Chrome Balls VS Steel BallsGrinding Classification

    I think in ball mills you can use steel balls which are very resistant to wear rates, but in SAG mills its tricky as the accumulation of small steel balls due to low wear rate in the mill will affect so much your power draw, meaning that your power draw will be high whilst grinding efficiency is reduced as in SAG mills you need larger steel balls, this will cause a reduction in throughput.

  • Mechanical Disruption Methods Beating

    For instance, a grain of rice is only about 20 mg, and easily fits in a well of a deep well plate, but the 5/32" grinding balls used in that format have insufficient mass to crack the rice. To pulverize the rice requires a 4 ml polycarbonate vial with a 3/8" grinding ball. Approximately 35 of the mill volume, including the interstices within the ball bed, was loaded with 25.4 mm steel balls weighing 8 kg. Each grinding test was performed with 0.63 kg of the chromite ore or clinker for various grinding times from 0.25 min up to 16 min. Mill product size distributions were obtained by dry sieving. 3.
