Airswept mill. This mill can accept ores up to a lump size of 15 mm (in special cases up to 30 mm) and a moisture content of up to 15 %. The ground material is carried out of the mill in the stream of gas and collected in the highefficiency separator. Separator tailings are returned to the mill for regrinding.
This reliable, effective grinding technology dates back more than 200 years, and has since designed, manufactured, and installed more than 8,000 ball/pebble mills, all over the world. Both the ball and pebble mills utilize a tumbling media, ball mills with steel balls, and pebble mills with ceramic or the natural rock itself.
The type of mill also can affect the selection of grinding media. Ball Mills use very large media while Attritors employ media ranging in size from 1/8" to 1". Horizontal mills require much smaller media, as small as mm to 2 mm. To read detailed specs and submit a quote, click here for our metallic media or here for our nonmetallic media.
