Solutions that meet strict industry regulations.
The asphalt manufacturing process consists of drying and heating aggregate (crushed rock, gravel, reclaimed asphalt pavement or sand) and filler (dust, fly-ash, lime or baghouse fines) and combining them with approximately 5% by weight of heated bitumen.
Cement consists of very hard and abrasive dust particles. Being very abrasive, this dust type rapidly wears out filter bags. To ensure the filters do not fail, frequent filter bag replacement is needed.
Before being heated to reduce the moisture content, the process of calcination of gypsum starts with quarrying raw gypsum and then size reduction of the rock through various methods which all cause dust.
The mining industry has strict EPA regulations to meet, as well as the concerns about protecting employees from potentially hazardous dust. Involving extraction, conveying, grinding, processing, sizing and packaging, these processes generate particulate [dust] that must be controlled.
