    What is high chromium alloy cast ball

    Release time:2021-03-24     Views

    High chromium alloy casting ball is a kind of chromium casting ball. Other low chromium casting balls and medium chromium casting balls are distinguished according to the content of chromium.

    For a long time, low chromium balls and forged steel balls are still widely used as abrasives in some ferrous (iron ore) and non-ferrous metal processing industries at home and abroad. Although some grinding ball manufacturers have done a lot of work by using high chromium ball instead of low chromium ball and forged steel ball, due to their own grinding ball product quality is not good enough, there is no good wear resistance (hardness is lower than hrc56-59, wear resistance is only 1.5 times of ordinary low chromium ball), sometimes even a large number of grinding balls are broken, in short, the cost performance is poor, which can not bring good benefits to users Good economic benefits, so has not been able to change the status quo. Practice has proved that it is a trend to replace low chromium ball and forged steel ball with superhard high chromium ball. Most foreign mines have already used superhard high chromium ball as grinding body.

    High chromium ball wear single bin 30g, three bins total 90g. 90 g = 0. 09 kg x 8 yuan = 0. 72 yuan per ton of cement (the current market price of high chromium steel ball is about 8000 yuan) because there is almost no breakage and out of roundness of high chromium steel ball under normal operation, which greatly reduces your labor and workload (if the ball is broken and out of roundness, you have to clear and load the warehouse, which is time-consuming and affects the output). At the same time, it also improves your output per hour, which is calculated according to 2 tons of cement produced for you in one hour (relatively, it can save about 70 degrees of electricity, generally about 3 or 2 meters, and the power consumption per ton of cement is about 35 degrees). It means that if you produce 20 hours per shift, you can produce 40 tons more cement for you, which saves about 1400 degrees of electricity.

    If you use high chromium ball, the cost of a ton of cement steel ball can save you 0, 48 yuan a ton. Under the same operation condition, you can produce 2 tons more cement in one hour. According to 40 tons more cement in one shift, the electricity cost of 40 tons is saved.
