Document Type and Number:
Japanese Patent JPS5125404
Kind Code:
A
Abstract:
A pipe for gunning a slurry of refractory material and water is rotatably received within a tubular boom. The composition of the slurry is maintained uniform by a water control valve before a mixing tee. The boom is encased in insulation and cooled by a flow of compressed air through an internal annular space around the rotating gunning pipe. The boom is received within roller supports in a barrel framework to permit the longitudinal extension of the boom to be varied. The barrel rocks up and down in a bracket on a turntable which swivels upon a motorized carriage. The longitudinal movement of the boom relative to the barrel and rocking of the barrel and contained boom are actuated by hydraulic piston and cylinder assemblies.
