grasancrusherSeptember 12, 2012, Mansfield, OH – The KRH1515, Grasan’s largest
road-portable primary impact crushing plant, can be configured for
concrete/asphalt recycling (side discharge) or crushing limestone (end
discharge), providing reduction ratios as great as 30 to 1 in closed
circuit.  The plant features the Hazemag
APPH impact crusher with a fully automatic, hydraulic cylinder system that
provides increased crusher capacity (up to 600 tph) smoother operation and more
uniform products.

Crusher adjustments have been simplified so no tools are needed.  The crusher inlet is 45 inches high, ten
inches greater than previous models, to handle larger sizes of incoming
material, and a hydraulic moveable inlet base helps clear jamming and
bridging.  The hydraulic inlet hood is
secured with wedge pins for easy opening and closing.  To reduce users’ spare parts inventories,
side-liners in the crusher have been reduced from seven to three standardized
shapes and all multi-blocks have been made interchangeable.  A grizzly bypass chute makes it easy to keep
or reject undersize material.

      

The Grasan KRH1515 is available with diesel or electric power and
includes a skid-on, skid-off hopper and six independent hydraulic support legs
for easy setup and tear down without a crane.
