BLM Steel Grinding Balls are made by using a proprietary combination of alloy elements to create a high carbon nano steel. Billets of this steel are forged while using a proprietary heat-treating and cooling process. This process provides the high impact, minimal deformation and extended wear properties of BLM Steel Grinding Balls. In competing test against traditional high chrome steel balls at Anhui Conch Cement the top cement company of the world, BLM Grinding Balls delivered many significant benefits. Results of these test included: BLM  required 7.5% less balls in weight  . BLM  reduced power consumption for operating the grinding mill by 7.4%  . BLM average output of tons/hour was 8.5% greater.  BLM grinding balls showed a 9.1% decrease in wear rate
