The new Terex Cedarapids MVP450X cone crusher was also on display in the Terex booth. The crusher boasts major new enhancements, including high-speed clearing of jammed material, quick crusher separation capability for fast manganese changes, and easy-to-operate computer controls. The optional “Guardian” PLC control system optimizes production and is fully automated, according to the company. The 400-horsepower crusher incorporates pinned cylinder ends that remove quickly to allow fast cone separation for faster manganese changes. At the press of a button, fully guided dual-action tramp relief cylinders provide 6-inch lift for easy clearing of jammed feed material to reduce downtime. The company says the hydro-pneumatic tramp iron relief system instantly resets the crusher setting after passing uncrushable material without having to activate valves and pumps. The hydraulic-powered threaded upper assembly allows for quick crusher setting adjustment under load.
