Mar 01, 2019 · 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.

The highest RCS concentration was measured on a crushing machine tender at site C. Crushing tenders’ exposures at site C were higher when the dust cannon was used (GM = 151.7 µg/m 3) compared to when the water spraying system was applied (GM = 65.2 µg/m 3) (P = 0.14).

2016. 3. 14. · 2/29/2016 2 BENEFITS OF DUST CONTROL 1. MORE PRODUCTION –Good dust control is good process control. If it doesn’tgo up in the air or spills on the ground, it goes into a truck and acrossthe scale. 2. HIGHER PROFITS –Water added for dust control goes across the scale and can payforasystemin6to 18months. 3. MACHINERY LASTS LONGER –Idlers, rollers, …

Crusher dust is a common by-product of mining and quarrying. With relatively low production costs compared to other building materials and numerous practical applications around the home and in construction, using crusher dust can be a big plus for the environment and make good economic sense.
