The hardness of grinding media ball how to choose balls

Ball mill, the harder the hardness of the ball, the better? Grinding media Ball is one of the essential parts of ball mill The quality of grinding media ball affects not only the productivity of the ball mill, but also the consumption of ball, and then affects the cost of grinding mediumChrome Balls (steel type 52100) are throughhardened and tempered steel balls designed to achieve maximum strength and quality Ball hardness is in the 60–67 HRC range They wear better than 440C stainless steel and throughhardened carbon steelGrinding Media Grinding Balls Union Process, IncHigh Cr media for primary grinding will typically contain maximum levels of eutectic carbide (30 – 35% by volume) and are heat treated to their maximum hardness (HRC 65 – 68)Cast Grinding Steel Balls 911Metallurgist

GOST 75242015 "Steel grinding balls for ball mills"

Russian national standard (edition 2015) is applicable to the grinding balls manufactured by rolling and forging method and used for grinding the raw materials in ball mills This document describes the requirements for raw materials and finished products (grinding balls); classification of grinding balls by groups of hardness and requirements; regulates the rules of labelling, packaging The Molycop range of SAG grinding balls is prepared for impact Through an innovative manufacturing process we’ve produced a ball with greater impact resistance and reduced spalling compared to the standard SAG ball, ready to perform in the highest impact SAG milling environments PRODUCT SPECIFICATIONS SIZE: SAG milling grinding media are available in sizes from 40” to 65” or 105 SAG MolycopGrinding media can be steel balls, steel rods, hard rock pebbles or the ore itself and the mill is classified accordingly The grinding mill reduces feed particles of 520 mm to optimum liberated size between 40 and 300 μm as required for beneficiation (a) Ball mill Ball mills (Fig 1217) are short cylindrical vessels with a shell to diameter ratio of 15 to 1 and less When the length to Grinding Mill an overview ScienceDirect Topics

Thus, full metallurgical characterization (eg chemical analysis, hardness profile, and microstructure) has to be conducted to select the suitable costeffective grinding balls (Pitt, Chang When hard pebbles rather than steel balls are used for the grinding media, the mills are known as “pebble mills” As mentioned earlier, pebble mills are widely used in the North American taconite iron ore operations Since the weight of pebbles per unit volume is 35–55% of that of steel balls, and as the power input is directly proportional to the volume weight of the grinding medium Ball Mills an overview ScienceDirect TopicsTable of ContentsData on Ball ChargesBall Mill Ball Wear ProjectionRecapitulation of Ball Wear FormulasPractical Application of Theoretical Conclusions In the previous discussion the fact was established that the work done by a ball when it strikes at the end of its parabolic path is proportional to its weight and velocity; then, since the velocity may be considered as constant for all the Grinding Media Wear Rate Calculation in Ball Mill
