How hard is your hard ore? Has the ore been tested and shown to be suitable for SAG milling? If the hard ore only comes to the plant from time to time the options are many options, including: accept a reduced throughput for a short time (minimum capital case); increase pebble crushing capacity and/or reduce crushed product size; return crushed pebbles to ball mill, bypassing the SAG mill.
