Typical crushing and screening operation

FOR IMMEDIATE RELEASE
(Free-Press-Release.com) January 9, 2012 --

Quarry blasts typically liberate between 10,000 and 15,000 and between 70,000 and 100,000 tons of material. The size of the blast and layout of the shot pattern must take the geology, structure, and weaknesses in the rock (mud seams), and neighboring properties, into account. A typical crushed stone quarry is not shown on this page. The blasted material is loaded into haul trucks to be transported to a fixed or movable stone crusher (Figures 2), but it is not uncommon for “load and carry” procedures to be used. Trucks vary in capacity, dependent on the needs of each operation, but typically range from 30 to 35 tons to 75 tons with about 50 tons capacity being the average. The crushed product is screened and stockpiled (Figure 3).
