Dust emission from crushing of hard rock aggregates
In this study, dust emissions and dispersion measurements were conducted under real operating conditions at six aggregate quarries in southern Finland. Five of greatly reduces the dust concentration in the production process of the open-pit quarry, and the comprehensive dust removal efficiency reaches more than 85%, which provides the Analysis on Dust Control Technology in Open-pit Quarry

Abstract. The production of aggregate for use in concrete production yielded a significant amount of fines fraction during the crushing operation at the quarry. The DROPLET SIZE. As spray droplets do most of the airborne dust particle arresting, correct nozzle selection is critical. Smaller droplets are used for finer dust particles or fine rising dust. These can be Spray nozzles ? a guide to dust suppression Quarry

“Hybrid Dust Suspension System” (Used In Stone Crusher) IJARIIE
While putting in place a hybrid dust suspension system takes an initial expenditure, doing so can result in long-term cost savings. The solution lowers the need for costly dust control procedures and maintenance, such as routine water spraying or manual dust suppression efforts, by minimizing demission’s. REFERENCES:-The dust suppression systems planned by MAITEK is patented for dusts reduction on the crushing plants and it is alternative to the traditional systems. It is a very efficacious solution for the suppression and reduction of the suspended dusts and in the air filtering..
