Application of "Fengxing" Brand Products in Molybdenum Industry Company

Luoyang * * Molybdenum Industry Co., Ltd. is located in Luanchuan County, Luoyang City, Henan Province. The ore hardness of the concentrator is f = 12-14, the particle size of the mill is -5mm accounting for 90%, the operation rate reaches 95%, and the fineness of the mill is -200 mesh accounting for 58% ~ 63%. The current production scale processes 7.8 million tons of raw ore annually, consisting of two 30 4.8 × 7m and a 30 3.6 × 6m overflow ball mill, before July 1, 2018, the concentrator has been using low chromium alloy cast balls as grinding medium. The contract price of steel balls is 3.1 yuan/ton of raw ore. Among them, machine #2 30 4.8 × 7m uses local Xichuan low chromium balls, abrading 0.65kg/ton of raw ore, producing 370 tons/hour and adding 5.8 tons of steel balls every day.

on July 1, 2018, the special high chromium balls for mines of our company were first used in the No. 2 mill of Luoyang Luanchuan Molybdenum Industry Group Co., Ltd. No. 3 mineral processing company. Due to the tight production task, the original low chromium balls in the mill could not be ground and cleared. Only the original low chromium balls in the mill could be replaced in the form of top balls. After four months, the abrasion consumption dropped to 0.34kg/ton of raw ore and the output increased to 420 tons/hour. Add 3.4 tons of balls every day.

: after using "phoenix-shaped" brand high chromium balls for mines, the grinding consumption of No.2 mill of No.3 mineral processing company decreased from 0.65kg/ton of raw ore to 0.34kg/ton of raw ore. in 2018, the price of our company's products was calculated at 7200 yuan/ton, and the cost of steel balls per ton of raw ore was 2.448 yuan. compared with 3.1 yuan of low chromium balls, the mining company could save 0.652 yuan/ton of raw ore, the annual cost of steel balls can save 11.084 million yuan. Due to our company's mine special high chromium ball in the application of low wear, low crushing rate, ball from large to small in the process of almost no deformation, grading stability, can greatly improve the production and grinding fineness, further improve the concentrate recovery rate, to create huge economic benefits for enterprises. The application of phoenix-shaped mine special ball can reduce the number of clearance, reduce the amount of ball, reduce the labor intensity of workers.
