When you add water to the feed of the cyclone, the result is the overflow becomes lighter and the underflow becomes heavier. The heavier UNDERFLOW DENSITY will give the ball mill more work to do. This is reflected in a heavier density being fed back into the hydrocyclone feed pump box. Which again changes the hydrocyclone operation performance.
WhatsApp: +86 18838072829The energy consumption in the ball mill was found to be kWh/t of ore with a targeted product size below 1 mm. The BWI of the ores varied from to kWh/t to reduce the particle size below 100 μ m, but in real time, the energy consumption is very high compared with the reported value of kWh/t.
