Our group uses hot rolling and forging technologies to manufacture grinding balls. Hot rolling is employed
for finished diameters less than 40 mm, while forging is used for finished diameters larger than 40 mm.
Our raw material stocks are medium and high carbon and low-alloyed steel produced by leading
metallurgical companies. Raw materials are subjected to strict chemical composition and geometrical
parameters before introduction into production streams.
The machinery used include Air Hammer, Induction Forging, Cooling, Quenching and Holding Systems.
Temperature is strictly controlled. As such induction temperature prior to forging, initial and final
quenching temperatures are monitored and controlled automatically.
The raw material is heated until control temperature is reached. The metal forming machinery is then
used to exert pressure on the metal blank. From there, the material is shaped precisely into required
dimensions with specific hardness, toughness, impact and abrasion resistance.
The characteristics of the balls are evaluated in our state of the art laboratory and approved by the QC
Director before shipment.
Our technical team is composed of experienced metallurgists, chemical and mechanical engineers. The
team is engaged in a continuous and rigorous research and development program to ensure we are
among global leaders in material usage, chemistry and production processes.
In order to produce balls resistant to breakage and spalling, material chemistry and heat treatment are
tailored to ball diameter and intended application to optimise mechanical integrity and wear resistance.
We consult our end users continuously for feedback on performance in order to adjust our operations, if
necessary, to maximise grinding efficiency and reduce grinding media consumption.
