Mill Selection. The first step in mill design is to determine the power needed to produce the desired grind in the chosen ore. The most used equation, for this purpose, is the empirical Bond equation (Bond, 1960, 1961; Rowland and Kjos, 1978).
In ball and race mill the coal passes between the rotating elements again and again until it is pulverized to the desired degree of fineness. The coal is crushed between two moving surfaces namely balls and races. A worm and gear drove the upper stationary race, …

RAYMOND BARTLETT SNOW Vertical Ball Race Mill is a durable design, power efficient, cost effectivecharacterized by consistent and reliable performance for greater productivity and has more than 250 installed fleet in successful operation.
Ball mills are simple in design, consisting of horizontal slow rotating vessels half filled with grinding media of ¼” to 1.5”. 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.
tion area, and thus design engineers must be familiar with different types of bearings, and their applications and limitations. As with all other types of machine elements, it is important to understand the FUNdaMENTAL operating principles of different bearings in order to select the right bearing for the intended application. Indeed, the
breakage tests do not include ball mill grinding data. Based on the 2009 CIM stone (Starkey and Samuels, 2009), the ratio of SAG to ball mill grindability is an important factor in achieving a reliable SAG mill circuit design because that ratio reveals the best and most practical split for SAG and ball mill energy for the ore being tested.
races may rotate against a ball or roll (in a Ring-Roll Mill the rolls may rotate while the ring is stationary). Ring-Roll (Bowl-Mill) and Ball-Race Mills comprise the majority of coal pulverizers currently in service at power generating facilities. Figure 3 shows a cut-away of a Ring-Roll type coal pulverizer. In this design the grinding rolls ...

In this instructable i will show you the basic design you will need to follow, in order to build a ball mill from lego. 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.
