The mill product can either be finished size ready for processing, or an intermediate size ready for final grinding in a rod mill, ball mill or pebble mill. AG/SAG mills can accomplish the same size reduction work as two or three stages of crushing and screening, a rod mill, and some or all of the work of a ball mill. Because of the range of mill sizes available, AG/SAG milling can often .

Get PriceThe Knife Mill GRINDOMIX GM 300 is suited for cryogenic grinding mainly of food samples, with the restriction that only dry ice and no liquid nitrogen can be used as the mill is not designed for temperatures as low as 196 °C. Rotor and cutting mills, however, accept both dry ice and liquid nitrogen as grinding aids. Due to the very low temperature liquid nitrogen is particularly .
Get PriceRod Mills your solution for grinding coarse materials. Available in multiple sizes. Designs extend to 15 feet x 22 feet (21 feet effective). Though mill length is limited by manufacturing constraints for the grinding rods, our Rod Mills are available in diameters from 5 feet up to 15 feet.
Get Pricemixer mill and Takacs and McHenry reported milling ball temperatures of 66 C[12, 13]. Comparably higher temperatures can be reached in planetary ball mills (PBMs), where temperatures from 60 to 600 C can be measured, depending on the type of PBM, the grinding stock, the grinding material and the ﬁlling degree [5, 13, 14].
