Low Breakage rate Dia 20mm-150mm Forged Steel Grinding Ball for
Mining
Description:
Hot-rolled steel balls are high-quality grinding balls manufactured
through rolling technology. Hot-rolled steel balls are formed by
heating round steel bars in a continuous heating furnace and then
sending them to a steel ball rolling mill for rolling. After
rolling, the red-hot steel balls immediately enter the heat
treatment equipment for quenching and tempering to ensure that they
have a high and uniform hardness. Finally, the qualified products
will be sent to the finished product warehouse for packaging and
shipped to customers.
Hot-rolled steel ball is a kind of ball milling ball using a new
rolling process technology.
