Grinding Balls

Our Grinding solution of cast alloy grinding balls are high abrasive resistant and falls under white
Cast grade containing certain percentage of chromium, with feature of Martensitic Base Structure and
Ultra Hard Chrome Carbides of which a balance created between Strength and Hardness achieved through
our four decade of expertise considering end use specific applications thereby achieving low wear
optimum grinding out-put, low specific consumption and negligible breakage resulting in minimum mill
downtime and maximum throughput.

Grinding Media Ball Features

  • Suggested microstructure achieved have martensitic base with discontinuous
    ultra hard chrome carbide in significant amount giving more wear resistance and
    less prone to surface oxidation in continuous use
  • The grades suggested by us with our expertise and experience gives you
    maximum recovery minimal specific consumption
  • Homogenous hardness throughout the section derives consistent wear thereby
    resulting in consistent and effective grinding
  • Grinding balls heat treated through globally accredited heat treatment furnaces
    gives precision and accurate results.

Service Provided

  • Optimal Grade selection for specific grinding application.
    SEL selects the best suitable grade out of our practical experience backed by our mineral characterisation lab and strong technical reasoning for the specific grinding application which results in cost minimization.
  • Optimal Ball sizing to maximize throughput and final grind.
    SEL improves the productivity of your mill by minimizing power usage, maximizing throughput and achieve the ideal surface area to achieve the target grind size and increase in revenue.
  • Trajectory Analysis to optimise grinding action and minimize ball liner impact.
    By optimizing the charge motion to ensure grinding media, the toe of the charge will result in the maximum of ore breakage and further more mill throughput. Trajectory analysis ensures grinding media is not being over thrown into the mill liner where the impact can lead to breakage of balls and liner and thereby minimizing operational cost.
  • Product performance follow up and real time monitoring.
    SEL Technical Services Team follow up and monitors the performance of our product on a real time basis with innovative practices and tools also support your mill production.
