Airborne dust generation is one of the byproducts of coal mining, processing, and handling. The amount of airborne total dust (ATD, respirable size and larger) and airborne respirable dust (ARD) generated is of primary interest for designing the level of engineering controls needed for adequate dust abatement. Laboratory crushing experiments were conducted in a wind tunnel with a roll crusher

The 911MPELRC Laboratory Roll Crushers are typically applied in laboratory or pilot plant applications after primary reduction of the infeed material. Roll crushers operate with a minimum of dust generation and produce a material with a tight size envelope containing a minimum of fines. Designed for rapid, controlled size reduction of ore, mineral or rock prior to metallurgical testing or

Our Jaw-Jaw i.e. 3-stage Stone Crushing Plants are most suitable for aggregate (0-20mm)/(0-40mm), production because: 1. Lower Dust / Fines Generation: Crushing takes place in 3 Stages – Primary, Secondary and Tertiary. This leads to a reduced crushing ratio in each stage, and hence lower fines generation
