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
Nov 18 2008 basic principle ball mill is generally used to grind material 14 inch and finer down to the particle size of 20 to 75 microns to achieve a reasonable efficiency with ball mills they must be operated in a closed system there is a specific operating speed for most efficient grinding
Generally filling the mill by balls must not exceed 3035 of its volume productivity of ball mills depends on drum diameter and the relation of drum diameter and length optimum ratio between length l and diameter d l d is usually accepted in the range 156164
In order to achieve good results with ball sizing the part must be ductile enough to allow the metal to flow we usually consider 40 rockwell c as the upper hardness limit for the process while 30 rockwell c and softer is ideal we manufacture ball sizing kits that come in a series of basic fractional diameters between 332" and one inch
The ball mill in closed circuit with hydrocyclones is an industry standard and well known methodologies exist for equipment sizing selection and design
a total apparent volumetric charge filling including balls and excess slurry on top of the ball charge plus the interstitial voids in between the balls expressed as a percentage of the net internal mill volume inside liners b overflow discharge mills operating at low ball fillings slurry may accumulate on top of the ball charge causing the total charge filling level to
Modelling mineral size reduction in the closedcircuit ball mill at the pine point mines concentrator international journal of mineral processing 1981 8 1 6178
Balls for ball sizing "ball sizing" is the process of forcing an oversized ball through the inside diameter of a metal part it will increase the inside diameter and greatly improve the surface texture of the part it is commonly used to assure an inside diameter size in elbows of tubing
Product description 1kg of 20mm white ceramic grinding balls 20mm diameter alumina al2o3 ceramic balls very hard wearing and ideal for ball milling for volume calculations 1kg will take up roughly half a litre 1kg of 20mm balls is roughly 55 balls but the exact quantity can vary
Aug 10 2020 use balls with a diameter between 13 mm and 19 mm inside the mill the number of balls is going to be dependent on the exact size of your drum for a cylinder drum of the size used above about 4060 balls should be sufficient larger drums will require more balls
