The mill product can either be finished size ready for processing, or an intermediate size ready for final grinding in a rod mill, ball mill or pebble mill. AG/SAG mills can accomplish the same size reduction work as two or three stages of crushing and screening, a rod mill, and some or all of the work of a
Ball Mills are generally used to grind material 1/4 inch and finer, down to the particle size of 20 to 75 microns. To achieve a reasonable efficiency with ball mills, they must be operated in a closed system, with oversize material continuously being recirculated back into the mill to be reduced. Various classifiers, such as screens, spiral ...

Wet Ball Mill kg kWh 0.16(A i-0.015) 0.33 Dry Ball Mill kg / kWh 0.023A i 0.5 Replacement Ball Size. Rowland and Kjos proposed the use of their equation for the determination of the initial and replacement media size. Azzaroni (1981) and Dunn (1989) recommended the use of the following expression for the size of the makeup media
Over the past 15 years, mine-to-mill studies have focused attention on the impact blast fragmentation has on concentrator throughput. Blasting provides the first opportunity for comminution or size reduction. It is also a cheaper and more efficient process, compared to both crushing and grinding.
mill throughput rates in the context of wide ranging vari-ability in ore hardness about a design point. Typically, mill throughput rates from a large open pit can vary con-siderably during the course of a few days, e.g., from 40,000 tonnes per day (tpd) to 80,000 tpd through a single grinding line.
During mine processing, throughput is a term used to express the expected time in hours it will take for tons of rock to grind to the target size in a ball mill. Mill throughput ranges from good throughput at 315 to 300 tons per hour (TPH), to bad throughput from less than 300 TPH to 250 TPH, to really
