power requirement for crushing stone miller in biomass
Crushing in Mineral Processing. Dec 26, 2015 Since there are not that many small SAG mill operations of under 2000 TPD, and most sub-2000 TPD mills are built with rod mills and/or ball mills only; the upstream crusher plant needs to have sufficient crushing power to provide a P80 to grinding of typically 1.5″ (40 mm) and often as finely crushed as 3/8″ (9 mm).

As such, it exposes the circuit to risk in terms of failing to meet throughput targets if insufficient SAG power is installed. Rather than design the SAG circuit with an arbitrary fraction of total circuit power, it is more useful to base the required SAG mill size on the product of the unit power requirement for the ore and the desired throughput.
