plain milling cutters that are more than 3/4 inch in width are usually made with spiral or helical teeth. a plain spiral-tooth milling cutter produces a better and smoother finish and requires less power to operate. a plain helical-tooth milling cutter is especially desirable when milling an uneven surface or one with holes in it. types of teeth,cyclones - resource book - wordpress.com,the purpose of the cyclones in the circuit is to size the mill discharge slurry. two product streams are generated by the cyclones; • a fine ‘overflow’ stream which reports to the leach/adsorption tanks. • a coarse ‘underflow’ stream that is recirculated to the mills for further grinding.
