Applying the water to the ore before it enters the crushing or grinding unit is most effective. In addition, it has been shown that the water pressure at early stages of crushing should be kept below 60 pounds per square inch (psi) to avoid pressurizing and forcing dust from the feed chute enclosures [NIOSH 2003]. The amount of moisture is not ...
