The SMC Test® is the most widely-used comminution test in the world for AG & SAG Mills, HPGRs and Crushers. Since its inception in 2004, SMC Testing Pty Ltd has conducted over 35,000 SMC Tests on behalf of the majority of the world's mining companies. These tests cover over 1000 different ore bodies across 80 countries and constitute one of the largest data bases of its kind in the world. The SMC Test, unlike any other comminution test available on the market, enables both power-based calculations and simulation studies to be conducted. It has been proven through benchmarking against an unprecedented 120 processing plants around the world, covering just about every type of comminution circuit in operation, including the largest to the smallest equipment available on the market, and treating from some of the softest to the hardest ores that have been discovered to date. This enables the SMC Test® to provide unparalleled versatility, precision and accuracy compared to other alternatives.
