As one of leaders of gold hardrock mining procedure industry, SBM always seeks innovation & excellence.
We have sold our jaw crushers to many different industries over the years, but the hard rock mining industry is still the #1 purchaser of our jaw crushers. The hammer mill or ball mill takes the <3/4″ discharge from the jaw crusher and pulverizes it to liberate the values in the ore (usually gold), and one of them is a component of our Turn-Key Ore Processor.
