process variables in this early stage may be very important. Figure 5-6. Scalping PRIMARY CRUSHING In stone quarries or in very "boney" gravel pits, large material usually is reduced in size by either a jaw (Figure 5- 7) or a gyratory crusher. Both types are compression crushers. Although economical, they have the tendency to

Quarrying of Stones: Its Methods, Selection of Site

Rocks are heated for a few hours by burning heaps of firewood over their surface. Such a process results in expansion of the upper layers and their cracking and separating from the lower layers. Quarrying of Stones by Blasting. This method consists of using explosives for breaking stones from very hard rocks.
