Mobile in-pit crushing --- product of evolutionary change.
Min Eng 1985 Jun; 37(6):578-580
Mobile in-pit crushing was first used in small limestone quarries with systems handling less than 1,102 short tons per hour. Since then, technology has advanced to include harder rock, including granite, copper ore, and waste rock. The mobile ability of these systems ranges from fully mobile units to fixed in-pit crushers including semimobile, movable, modular, and semifixed. Reasons for considering these systems include reduced cost, shorter haulage distance, more predictable future costs than trucks, more efficient energy use than trucks, and improvement in design to the point where mobile crushers are as reliable and rugged as stationary units.
