A mill is a device that breaks solid materials into smaller pieces by grinding crushing or cutting such comminution is an important unit operation in many processesthere are many different types of mills and many types of materials processed in them historically mills were powered by hand or by animals eg via a hand crank working animal eg horse mill wind or water

An online calculator lets you calculate top ball size of grinding media for your mill use this equation method to properly grind your ore
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
The optimal ball diameter in a mill calculation of grinding media in ball mill grinding quartz and copper ore in a laboratory ball mill there has been defined of the equation for determining the optimal ball diameter depending on the grain kinetics of grinding ceramic bulk considering grinding media contact pointsdoeringselection of
Ball mill size as a replacement grinding media wears and reduces in size at a rate dependent on the surface hardness density and composition of the ore ball wear is directly proportional to surface area per unit mass and thus inversely proportional to ball diameter other factors include speed of mill rotation mill diameter mineral density
Apr 06 2020 media motion about ball mill is established and the motion regimes of grinding media is simulated using the discrete element method dem with simplifying the contact model of grinding media 25082016 a slightly inclined or horizontal rotating cylinder iron ore ball mill grinding media calculation formula iron ore ball mill
The mill product can either be finished size ready for processing or an intermediate size ready for final grinding in a rod mill ball mill or pebble mill agsag mills can accomplish the same size reduction work as two or three stages of crushing and screening a rod mill and some or all of the work of a ball mill
To the feed side you can put three quarter to one inch minus here then ore enters into the scoop of ball mill with a twoton charge of balls the material works its way through the ball mill which turns about 35 rpm with the water addition to the discharge they will go on to the shaker tables for concentration
Jul 01 2016 the grinding media may be the ore itself autogenous grinding bars balls or cylpebs or even the ore itself together with a small amount of balls semiautogenous grinding a survey found out that approximately 53 of the grinding circuits around the world use ball mills and 38 use autogenous or semiautogenous grinding and therefore nearly 90 of mining operations are users of balls as grinding media
