Why we say we can increase the Iron ore mine output by using our grinding ball ?
Our grinding ball is made by alloy steel rod, which is produced by local best supplier, who can promise us best density, so compare with casted balls, our grinding ball weight is heavier than casted balls. This means, we need less grinding balls in the ball mill, give bigger space for Iron ore in ball mill, this can increase the output.
