Mining and Cement Industries with Large Consumption of Wear-resistant Balls Have a Detailed Analysis of the Economic Benefits of Using High-chromium Balls

I. First of all, take iron ore as an example: most mines generally use low chromium ball or forged steel ball, and its current price is about 5000 yuan/ton, and the consumption of grinding body per ton of concentrate powder is about 3Kg. If we use our company's special high chromium ball for mine, the current average price is 7000 yuan/ton (excluding freight, the same below), and the consumption of concentrate powder per ton is 1.5Kg/T. If we calculate the annual production of 100000 tons of concentrate powder in this mine, the actual consumption of steel balls per unit year will be greatly reduced by using special high chromium ball for mine instead of low chromium ball or forged steel ball, and the saving of steel balls is the direct benefit, The reduction of freight costs and the increase of Taiwan's production will also produce greater benefits. 1. The reduction of procurement cost caused by the reduction of wear: the original low chromium ball wear was 3Kg, the price was 5000 yuan/ton, and the total value of 300 tons of low chromium ball needed to produce 100000 tons of concentrate powder was 1.5 million yuan; At present, the special high-chromium ball for mine is used, with the wear of 1.5 Kg and the price of 7000 yuan/ton. The production of 100000 tons of concentrate powder requires 150 tons of high-chromium ball, with a total value of 1.05 million yuan. Save 450000 yuan by comparison. At the same time, a large amount of freight has been saved due to the substantial reduction in the purchase quantity. 2. From the point of view of the customer's production workshop, the use of special high chromium balls for mines is reflected in the consumption cost of 7000 yuan/ton of concentrate powder × 1.5 kg/t · concentrate powder=10.5 yuan, while using ZQCr2 low chromium ball, reflected in the cost of ball consumption per ton of mine is 5000 yuan/ton × 3 kg/t · concentrate=15 yuan, the cost of powder pellet per ton of concentrate is reduced by 4.5 yuan, and the production of 100000 tons of concentrate powder can save 450000 yuan, with considerable economic benefits. 3. Because the carbide in the matrix structure of the high chromium ball is dispersed, the content of carbide is high, and the hardness of the product after heat treatment oil quenching is high (martensite content is high), so the wear resistance is good, the wear is low, the grinding efficiency is high, and the grading of the ball in the mill is stable and not easy to change, which not only increases the fineness to a certain extent, improves the output per hour, ensures and improves the quality of the concentrate powder, but also prolongs the balling period, It reduces the labor intensity of workers. 4. Intuitively, the purchase cost of a ton of steel ball increased by 2000 yuan. In fact, according to the ball consumption, the actual steel ball price can be seen from the price comparison: (1500 g/ton × 7000 yuan/ton)/3000 g/ton=3500 yuan/ton; That is to say, the actual price of the steel ball used for the Zhongyi brand mine special high chromium ball is only 3500 yuan, and the reduction of wear reflects a reduction of 5000 - 3500=1500 yuan per ton.
