Novokramatorsky Mashinostroitelny Zavod (Kramatorsk, Donetsk region) shipped to the customer a ball rolling mill ШПС 60-100, designed to produce steel grinding balls with a diameter of 60, 80, 90 and 100 mm. Balls will be produced by cross-helical rolling with subsequent in-line heat treatment, meeting the requirements for their quality.
Until recently, NKMZ have not produced cross helical rolling mills. And only in 2018 the first ball rolling mill ШПС 20-400 was designed and manufactured for Energostil company (Kiev) here.
In contrast, the current machine features an increased productivity up to 100 thousand tons per year, includes a heating section, a full heat treatment cycle and a ball packing section, and allows producing balls of high hardness.
