A ball mill is a type of grinder used to grind, blend and sometimes for mixing of materials for use in mineral dressing processes, paints, pyrotechnics, ceramics and selective laser sintering It works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell
The operating principle of the ball mill consists of following steps In a continuously operating ball mill, feed material fed through the central hole one of the caps into the drum and moves therealong, being exposed by grinding media The material grinding occurs during impact falling grinding balls and abrasion the particles between the balls
Ball Mill Group No 3 LOGO Contents Introduction Types and Process Principle of work Description of Ball mill Design and Cost Introduction It is a device used for size reduction, It can reduce sizes up to a tenth of a micron Cylindrical in shape Rotates on a horizontal axis Partially filled with the material to be ground and the grinding medium
The ball mill is a tumbling mill that uses steel balls as the grinding media The length of the cylindrical shell is usually 1–15 times the shell diameter (Figure 811)The feed can be dry, with less than 3% moisture to minimize ball coating, or slurry containing 20–40% water by weight
Ball mills are simple in design, consisting of horizontal slow rotating vessels half filled with grinding media of ¼” to 15” The particles to be milled are trapped between the grinding media or balls and are reduced in size by the actions of impact and attrition

How to Make a Ball Mill With Lego and a Pvc Pipe ,
My design is very close to what you would expect from commercial lapidary tools (fancy work for rock tumbler/ball mill), except it runs off a lego motor rather than a 240v brushless The problem with ball mills though, particularly the commercial ones, is that the worst of them still cost around $100 bucks
Slice Mills™ are identical to the Ball Mills and Ceramic Lined Mills in diameter and design The only difference is that they are as little as 12” in length Since mill diameter dictates performance and mill length only affects capacity, Slice Mills™ are used to develop or ,
Calculate and Select Ball Mill Ball Size for Optimum Grinding
In Grinding, selecting (calculate) the correct or optimum ball size that allows for the best and optimum/ideal 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 and/or mill liner wear and tear
