Application of "Fengxing" Brand High-Chrome Grinding Balls in No.2 Mineral Processing Plant of Jinruyang Company

Gold * * Ruyang No. 2 Mineral Processing Plant is a large mineral processing enterprise with an annual design processing capacity of 5.92 million tons. The mill size is 7.32x 12m and overflow type. It originally uses low chromium balls from other manufacturers. The balls consume 0.67kg/ton of raw ore. The hourly output is 780 t/h with a crushing rate of 3% and a rounding rate of 6%.

due to the high wear, high crushing rate and high rounding rate of low chrome balls, the mill output has not been able to meet the standard and the grinding fineness is not ideal, so the use of high chrome balls for mines of Anhui Fengxing New Material Technology Co., Ltd. will be used in August 2021, with remarkable results. The current ball consumption is stable at 0.4kg/ton of raw ore, and the crushing rate is less than 0.2%. The output per hour increased to 820t/hour, with very few missing round steel balls.

economic benefits;

high chromium ball is 8900 yuan/ton, and the ton cost is 8900x 0.4=3.56 yuan/ton.

low chromium ball unit price 5800 yuan/ton, ton cost: 5800x 0.67=3.93 yuan/ton.

annual cost savings: 820t/hx24hx330 days x(3.93-3.56)= 212544.00 yuan
