Low-chromium alloy is widely used in ball mill
During this period, domestic and international low-chromium alloy casting ball is the fastest growing alloy casting ball, which is applied in the second and third sections of grinding in large and medium-sized concentrator and small and medium-sized ball mill.
(1) JISCO dressing φ2700 mm × 3600 mm mill the Ningguo Factory production of wear-resistant materials, high-carbon low-chromium cast the ball into the industrial test, the ball consumption of the original Carbon Ball 0 82 kg / t – to 0 276 kg / t, saving 66%, wear a multiple of 2.97, the annual benefit of over 40 million.
(2) Shanghai Meishan iron ore concentrator. Φ2700 mm x 3600 mm, ball mill using low chrome alloy casting ball, the ball is consumed by the Carbon Ball 2.27kg / t – reduced to 0.733 kg / t,. The obvious saving, 4-year section of the ball 3 000 t, and efficiency 71 million.
(3) the Jiangxi iron pit iron ore concentrator. Industrial test φ2700 mm x3600 mm ball mill using low chrome alloy casting ball, the ball consumption the former Putan ball 0.6 kg / t – reduced to 0.259 9 kg / t.
(4) of Tongling Nonferrous Metal Lion Copper Mine. Trial low-chromium alloy φ3200 mm x 3100 mm mill, ball consumption the former Putan ball 1.85 kg / t reduced to 0.63 kg / t, t ore ball fee reduction to 0.46 yuan.
(5) Baiyin Nonferrous Metals concentrator. Φ2700 mm x 3600 mm mill on the industrial test of low chrome alloy casting ball, the ball consumption the former Putan ball 1.99 kg / t reduced to 0 73 kg / t, t ore ball lower costs 0.726 yuan. Then ore processing 600 000 t count, the New Year ball 756t.
(6) Zhangjiakou gold concentrator low chrome alloy casting ball, the ball is consumed by the Carbon Ball 2.10 kg / t reduced to 0.816 kg / t, the annual saving grinding balls cost of 170,000 yuan.
(7) the Magang Gushan iron ore concentrator. Maanshan City, wear-resistant metal casting and forging materials company production of low-chromium alloy, used in the period of φ2700mm x 3600 mm mill, ball consumption original Carbon Ball 2.77 kg / t reduced to 1.35 kg / t – annual ore processing 400 000 t total grinding balls costs savings of 230,000 yuan.
(8) Zhengzhou Aluminum Plant. Industrial test of the the Ningguo cast steel plant production φ120 mm high toughness low chromium homes in gold ball, the ball consumption the original No. 45, forged steel ball of 1.62 kg / t reduced to 0.521 kg / t, t ore grinding balls fee low l 1 million. Total of 800 000 t annual grinding bauxite, save money 860,000 yuan.
