Basically, there are three types of
grinding media, up-set forging balls, rolling forged balls, and
cast balls. CEGV supplies rolling forged balls and cast balls.
Rolling forged balls:
The advantage of rolling forged balls is that they have much
better uniformity and stability. Depending on working
environment, end users may select rolling forged balls or cast
balls. Depending on the size of mills, type of mills, and
mineral concentrates, rolling forged balls may have better
performance than cast balls.
We are the only one in China
who manufacture rolling forged balls up to 5". Due to the fact
that rolling forged balls are made from steel bar with fully
computerized manufacturing process. Our products have much
better stability and with our special designed heat-treatment
process, our products have better uniformity. Stability refers
to quality variance among individual balls and uniformity
refers to how uniform a ball will be. Stability and uniformity
can lead to improvement on the productivity of grinding media.
Our rolling forged balls have
been supplied to Codelco in Chile, Barrick Gold in Tanzania, and
Anglo American in South Africa, Chile, and Brazil. The
performance has been proofed being top class in the world. In South Africa Platinum mine and
Brazilian Nickel mine, the performance has been improved up to
37.5% comparing previous products.
Cast balls used
to be used mainly in cement industry but in mining industry, due
to poor ductility and the size of mills in mining industry, it
is rarely used. During past few years, the technology of
manufacturing cast balls has been significantly improved. Now,
cast balls have achieved good performance in mining industry.
significant price advantage for this product since cast balls
are a labor intensive product which can utilize labor cost
advantage in low cost countries.
