With a mechanical filter, filter efficiency and the pressure drop across the filter increases as the filter begins to load. The increase in pressure drop will decrease airflow, which will eventually result in unacceptable air quality, and potentially cause leaks, leading to a decrease in the efficiency of the system to reduce respirable dust.

Crushing has a significant effect on dust concentration at DW direction, which is seen from the major drop in dust mass concentration level during the break in crushing (Fig. 3, Fig. 4). The concentration drops quickly, within a minute, to a lower level, when the mobile crusher was on pause.
