    Jun 01 2020 · This paper presented a new method for producing grinding media for ball mills based on the cross wedge rolling technique. It is a medium-throughput technique i.e. its throughput is higher than in die forging but lower than in skew rolling. The paper investigates typical failure modes which may occur during the rolling process.
