Gold plant pebble crushing | Henan Deya Machinery Co., Ltd.
Pebble crushing, almost a standard for SAG circuits today, was controversial early in the development of autogenous grinding (AG) SAG milling. This was largely due to the fear of failing to efficiently separate grinding steel from the recycle load, with subsequent crusher damage. Magnet and metal detector manufacturers have minimized this ...
