evolution of grinding models which incorporate liberation as a parameter Andrews and Mika 1976 Peterson and Herbst 1985 Choi 1986 A n With the existing size reduction models much work has been donein studying the effect of operating parameters such as mill speed and ball

plant ball mill’s grinding efficiency Fig 1 The functional performance parameters “mill grinding rate through the size of interest” and “cumulative mill grinding rates” from both plant and smallscale tests are applied to this task A plant media sizing methodology and

grinding Ball size distribution inside an industrial mill was analysed in terms of shapes and sizes Load behaviour mill power and breakage as affected by media shapes were studied in a pilot laboratory mill An inductive proximity probe light

81 Grinding 811 Grinding action Industrial grinding machines used in the mineral processing industries are mostly of the tumbling mill type These mills exist in a variety of types rod ball pebble autogenous and semiautogenous The grinding action is induced by relative motion between the particles of media the rods balls or pebbles

grinding media wear rates throughput power draw and product grind size from the circuit Each of these performance parameters peaks at different filling values In order to continuously optimize mill operation it is vital to obtain regular measurements of the ball load and pulp position The current way to measure the charge filling degree

Balls for use in mineral processing ball milling operations are designed for maximum abrasion resistance using high carbon content and high hardness levels PRODUCT SPECIFICATIONS SIZE Molycop supplies cast high chrome grinding balls for use in ball milling and regrind applications in nominal sizes from 15 mm to 90 mm in diameter

Reliable and effective grinding technology for diverse applications With more than 100 years of experience in developing this technology Metso has designed manufactured and installed over 8000 ball and pebble mills all over the world for a wide range of applications

Ball mills tumble iron or steel balls with the ore The balls are initially 5–10 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 The ball mill is operated in closed circuit with a particlesize measurement device and sizecontrol cyclones

In Grinding selecting calculate the correct or optimum ball size that allows for the best and optimumideal or target grind size to be achieved by your ball mill is an important thing for a Mineral Processing Engineer AKA Metallurgist to do Often the ball used in ball mills is oversize “just in case” Well this safety factor can cost you much in recovery andor mill liner wear and
