Engineering Controls Database

Hammermill and impact crushers use a rotating device (hammers) to thrust the ore against the outer walls of the crusher with the intent to break the ore by impaction against the outer surface. Because the ore is impacted at high velocities to induce breakage, high dust generation and liberation rates can occur from these types of crushers.

Engineering Controls Database

The dust-laden air is then directed to a nearby return, a bag house, or a fan-powered dust collector where it is captured by filters and the clean air can be discharged into the mine air [NIOSH 2003a]. Figure 2 shows a conceptual approach to control crusher dust in a stone mine using a closed ventilation system. Figure 2 - .
