Abstract. Background/objectives: A large number of labourers work in the stone-crushing industry in India. Many of these workers are also exposed to high levels of particulate matter in their homes from the use of biomass fuels. As part of our investigations to examine the health of these workers we characterised their exposure to respirable

Abstract. Various types of rock fracture occur at different loading rates. For example, rock destruction by a boring machine, a jaw or cone crusher, and a grinding roll machine are within the extent of low loading rates, often called quasistatic loading condition. On the contrary, rock fracture in percussive drilling and blasting happens under

Thus the stone may be crushed with smaller stroke count and smaller stroke length. The capacity of the crusher and the crushing plant may be increased because the mineral material is crushed and does not stay waiting for a new stroke. Crushing work done by a smaller stroke also affects other components of the crusher which may be lightened if

Typically, a crushing circuit includes two or three crushing units, but up to five crushing units can be applied. Secondary and tertiary crushers are usually cone or gyratory crushers. An impact crusher is rarely used with hard rock materials due to wearing. Commonly, an encapsulated sieve is adopted together with every crushing unit apart from the primary crusher. All processes of aggregate
