Page 44 of 113 ROCK products • February 2019 • 41 Crushing and Breaking From the quarry face, material is trucked to the primary crusher, a Hazemag impactor. The heavy-duty crusher has a capacity of approximately 2,500 to 3,000 tph. "We also use a secondary breaker, a Cat 349 with a Cat hammer, as needed," Griffin said. From the primary, the stone is moved to a secondary crusher, which is also a Hazemag impactor. The secondary crusher breaks the stone down to 4.5 in. From there, the secondary crushed stone is conveyed to the fractionated wash plant for cleaning and sizing. Loading happens into either rail cars or trucks. Our tertiary crushers are manufactured by Sandvik," Griffin said. Conveyors criss-cross the plant moving stone to the secondary crushing and screening operations. The plant is highly automated and production points are monitored by camera. WE'RE LOWERING THE BOOM ON YOUR OVERSIZE.
