ball mill design. a survey of australian processing plants revealed a maximum ball mill diameter of 5.24 meters and length of 8.84 meters (morrell 1996). autogenous mills range up to 12 meters in diameter. the length-to-diameter ratios in the previous table are for normal applications. for primary grinding the ratio could vary between 1:1and ...
ball end mills are used for drilling shallow holes slotting a channel where a flat bottom is not required or most commonly used to produce multi-dimensional contours in molds or dies. the design of ball end mills forms a hemispherical cutting action identical to the diameter of the tool. because of the shapes required in these products it’s common that multi axis machining
gives the optimum composition of 40% 50.8 mm ball and 60% 25.4 mm balls for a 1 m diameter mill and 27% 50.8 mm and 73% 25.4 mm for a 2 m diameter mill when grinding from a 90% passing 9.5 mm feed to an 80% passing 150 μm product. the portion of 50.8 mm balls decreases as the feed size or the product size decreases.
