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
When charging a ball mill ceramic lined mill pebble mill jar mill or laboratory jar use on a jar rolling mill it is important to have the correct amount of media and correct amount of product charging a dry mill the general operation of a grinding mill is to have the product impacted between the balls as they tumble
In ball mills steel balls or hard pebbles to break particle based on impact and attrition a rotating mill charged with media and ore is lifted against the inside perimeter some of the media falls and impacts the ore particles at the bottom of the mill the rest of the media cascades and in the process creates particle breakage by attrition
As a thumb rule powder to be milled should be taken as 25 of total ball weight if the quantity of charge is very less then milling balls will start to collide with each other and no milling will
Highenergy ball milling is effective in getting welldispersed slurry 79 the preparation procedure is summarized in fig 242first commercially available pzt powders apc 850 were highenergy ball milled to get the desired particle size secondly a selected dispersant was added to the milled powders to get the surfacemodified powders
831 rod mill charge rod mill charges usually occupy about 45 of the internal volume of the mill a closely packed charge of single sized rods will have a porosity of 93 with a mixed charge of small and large diameter rods the porosity of a static load could be reduced even further
We can calculate the steel charge volume of a ball or rod mill and express it as the of the volume within the liners that is filled with grinding media while the mill is stopped the charge volume can be gotten by measuring the diameter inside the liners and the distance from the top of the charge to the top of the mill the loading or change volume can then be read off the graph below or
When charging a ball mill ceramic lined mill pebble mill jar mill or laboratory jar use on a jar rolling mill it is important to have the correct amount of media and correct amount of product charging a wet mill the general operation of a grinding mill is to have the product impacted between the balls as they tumble
