Iron Ore

Sree Balaji Metacast Industries has perfected and the patterns, moulds and dyes for these parts. This enables us to respond to all enquiries competently and execute orders within months instead of other vendors who take more than a year.

Pellets are a highly customized product. They are an essential part of effective and continuous functioning of huge machinery being sourced from China. The demand is recurring and continuous throughout the year. We understand that lack of such essential spare parts can result in loss of productivity and peak plant utilization.

A thoughtfully designed sophisticated manufacturing process uses optimised material composition to significantly enhance the output of our clients. The High Chrome and Oil Quenching Heat process enables these balls to be hard working and wear-resistant. The right material is crucial in the longevity and trouble-free functioning of the spare parts.

GRINDING MEDIA BALLS & CYLPEBS

Hyper Steel Grinding Media Balls

High Chrome Grinding Media Balls

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.
