High chromium alloy cast ball, is a chromium cast ball, low chromium cast iron balls and other medium chromium cast ball, is based on the content of chromium to distinguish.

Long term since the domestic and foreign some black metal (iron ore) and non-ferrous metal processing industry will still low chromium ball and forged steel ball as a grinding body is still widely used. Although the use of high chromium substitute low chromium ball and forged steel ball use has done a lot of work some ball manufacturers, but due to its own ball product quality is not perfect, there is no good abrasion resistance (hardness is lower than HRC56-59, the wear resistance of low chromium ball only 1.5 times), sometimes even appear a lot of crushing grinding ball wait for a circumstance, anyhow is price difference, not bring good economic benefits to the users, so it has been unable to change the status quo. Practice has proved that the mines superhard high chromium instead of low chromium ball and forged steel ball used must be a kind of trend, the majority of foreign mines are already using ultra hard high chromium ball as a grinding body.

High chromium wear single bin 30 grams, 90 grams of a total of 3 warehouse. 90 grams of =0. 09 kg X8 yuan =0. 72 yuan a ton of cement (high chromium steel at present market price in 8000 yuan) because of the high chromium in normal running condition there is almost no breakage and loss of circle, thus greatly reducing your labor and workload (such as a ball was broken and the loss of a round, you have to rummage binning the time-consuming also affect the yield). At the same time also increase your production to Taiwan, according to an hour to give you 2 tons of cement production calculation (relative and can save electricity 70 degrees, generally 3, 2 meters of mill tons of cement consumption in 35 degrees or so). According to a class of metaphor production 20 hours to count, can give you 40 tons of cement production, thus saving electricity about 1400 degrees.

If with high Cr, a ton of cement ball cost can give you save 0, 48 yuan a ton. In operation under the condition of the same one hour and can give you much production of 2 tons of cement, according to a class of more than 40 tons of cement 40 tons of calculation, the electricity saving.
