InGrinding, selecting (calculate) the correct or optimumball sizethat allows for the best and optimum/ideal or targetgrind sizeto be achieved by yourball millis an important thing for a Mineral Processing Engineer AKA Metallurgist to do. Often, theballused inball millsis oversize “just in case”.
I believe that as circulating load in aball millincreases beyond a critical point themill powerdraw begins to fall so there is an adverse effect ongrindingefficiency (apart from the obvious physical problems it causes like high scats rates, balls discharged frommill, sumps overflowing, cyclones clogging up etc.).

1 Calculation of ball mill capacity. The production capacity of the ball mill is determined by the amount of material required to be ground, and it must have a certain margin when designing and selecting. There are many factors affecting the production capacity of the ball mill, in addition to the nature of the material (grain size, hardness, density, temperature and humidity), the degree of grinding (product size), the …

May 22, 2019· Theball millconsists of a metal cylinder and aball. The working principle is that when the cylinder is rotated, thegrindingbody (ball) and the object to be polished (material) installed in the cylinder are rotated by the cylinder under the action of friction and centrifugal force.
Jun 25, 2018·Milleffective diameter = 2.23 m . 335 is a constant used for drygrindingwith steel balls in themill. Actual size of media is taken is lower than the calculated value. It is around 80 to 90 mm. If you Wants to reduce the maximumballsize, thenreduce the feed size by using pre-grindingoperation.
