Grasan’s largest road-portable impact crusher plant, the KRH1515, features the Hazemag APPH primary impact crusher with fully automatic, hydraulic cylinder system that provides increased crusher capacity (up to 600 tons per hour), 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 higher than previous models, to handle larger sizes of incoming concrete and asphalt rubble and C&D debris; 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 shapes to three standardized shapes, and all multi-blocks have been made interchangeable. The feeder pan under the crusher discharges out the side for improved handling of wire mesh and rebar. A grizzly bypass chute makes it easy to reject or keep undersize material. A skid-on, skid-off hopper and six independent hydraulic support legs facilitate easy setup and tear down without a crane in about 30 minutes. Diesel or electric power.
