The dust control system Commissioned near primary
Figure 2 shows the dust control system commissioned near primary jaw crusher and primary siever where cyclonic mechanism and bag filter assembly are seen alongwith the dust collectingDust constitutes one of the major environmental concerns near many aggregate quarries, with crushing often being the most significant source In this study, Dust emission from crushing of hard rock aggregates
Dust emission from crushing of hard rock aggregates
Jaw crushers are mainly used for primary crushing in Finnish hard rock quarries Crushing usually includes several crushing phases Typically, a crushing circuit Crushing produces mainly coarse (TSP and PM 10) dust particles which settle near the dust source The mass concentration of coarse particles varied from few tens of μg/m 3 to over 6 × 10 3 μg/m 3 downwind from the crusher The mass concentration of fine particles (PM 25 and PM 1) ranged between ten μg/m 3 and few hundreds of μg/m 3Dust emission from crushing of hard rock aggregates

Crushers QueensMineDesignWiki
Crushers play an important role in the material handling process for underground mine operations The main purpose of a crusher is the size reduction of the feed This size reduction is achieved by applying a force to the material, creating cracks in the material which in the end will cause the material to break into smaller piecesThe term “primary crusher,” by definition, might embrace any type and size of crushing machine The term implies that at least two stages of crushing are involved, but in many cases the machine which performs the function of initial crusher is the only crusher in the plant The factors influencing the selection of a crusher for this servicePrimary Crushing 911 Metallurgist
