Interviewing individual baggers helps inform efforts by mining companies to reduce dust sources and worker exposure levels. Baggers say they were aware that dust is continuously produced in their environment. Perhaps helping baggers identify primary sources of dust can help reinforce that the presence of dust requires awareness on the job.

What Is Mining Mill Dust In Aggregate

Crusher Dust Aggregate: Crusher dust is a byproduct of the mining and quarrying industry and differs from roadbase in that it consists entirely of smaller particles. As the name suggests, crusher dust is made as a result of crushing an object, in this case rocks and metals, producing large amounts of dust filled with small rock and metal .
