Factors Influence Ore Grinding Mill Efficiency - JXSC

2019-5-10 At present, “more crushing and less grinding” is one of the main principles of concentrator design and production. Take a gold mine as an example, reducing ore particle from -15mm to -10mm improve the grinding efficiency from 1150 tons per day to 1500 tons per day, and decrease the steel consumption and electric power consumption by 1.53kg/t to 1.1kg/t and 41.57kWh to 29.2kWh
