Too many grinding balls can prematurely wear out the grinding balls themselves. Operating a mine mill requires balancing a dynamic set of tradeoffs. Each of these tradeoffs will impact the overall operating conditions of the comminution circuitwhich means that every other variable now faces a new set of conditions to be optimized against.
