Cylpebs
Conventionally, grinding media was made of cast iron, cast steel and even through forged process. However, Hyper Steel grinding media has surpassed the conventionally produced grinding media in terms of performance. A minimum 50% reduction in wear rate is expected over conventional grades. SBMI is one of the highest suppliers of quality hyper steel grinding media and castings.
