Get Price And Support Online; comparison of power consumption in iron ore wet and .

Power Measurement: the only accurate way to measure mill power is to directly measure power or torque input to the shaft. Indirect measurements are inaccurate and will underestimate mill power (Nesset, J.E. et al, Assessing the Performance and Efficiency of Fine Grinding Technologies, 38th Annual Meeting of the CMP, Canada, January 2006).

Low Electric Power Consumption Mining Ball Mill In Tantalum Ore 110KW . Energy saving ball mill features: 1. Low noise, finished grain shape is excellent, saving energy and electricity, turn smoothly, high. production efficiency, reliable operation, and low vibration, the big crushing ratio, little wearing parts. consumption, etc. 2.

A SAG mill with a 44' (13.4m) diameter and a power of 35 MW (47,000 HP) has been designed. Attrition between grinding balls and ore particles causes grinding of finer particles. SAG mills are characterized by their large diameter and short length as compared to ball mills.

For a single mine, average comminution energy consumption can be approximately 6,700 kWh /kiloton. Grinding is accomplished by abrasion and impact of the ore with moving media such as rods (rod mills), balls (ball mills), or pebbles (sized ore in AG & SAG mills). These vary in size according the size of particle being processed.
