Get PriceSAG and AG Mills operate by lifting ore/grinding media and dropping it on the operating bed of the mill charge. High impacts from lifting ore and media promote impact breakage which is the primary mechanism for size reduction in the mill. Via the use of sophisticated instruments and software, we closely monitor the mill impact location to boost the grinding efficiency of your operation.

Get PriceGrindingExpert™ automatically adjust feed rate, mill speed and water addition to reduce upsets, eliminate grind-outs and increase tonnage in SAG / ball mills. We constantly maintain desired operating conditions by monitoring bearing pressure, power, recycle pebbles, mill density and mill acoustics. On average, expect a 3-6% increase in SAG mill throughput over an operator/DCS system.
Get PriceBall mill rotating speed: when grinding ball adding rate remains constant, the useful power of ball mill varies with the rotating speed, therefore, production efficiency will also be influenced. Ball mill rotating speed need to be adjusted according to different types of ores. If the motor power is large enough, increasing rotating speed properly is an effect way to improve production.Usually,
