FLUSH MOUNTING UNENCUMBERED TONGUE-ADJUST UNDERCUT DEVICE FOR SPIRAL SEPARATORS

摘要

ABSTRACT OF THE DISCLOSUREThis invention relates to a take-off assemblyfor mounting in a spiral separator. The take-off assemblyincludes an adjustment tongue and a mounting member con-taining a transverse aperture for receiving the adjustmenttongue. The mounting member has a surface surrounding theadjustment tongue which is substantially flush with thetop surface of the adjustment tongue. There is also pro-vided an undercut for obtaining an undercut of concentratesparticles from pulp flowing in the spiral separator wherebytailings and/or middlings contained in an upper portion ofthe pulp above the concentrates particles may flow acrossthe transverse aperture.There is also provided a spiral separator for gravityseparation of minerals containing the take-off assembly anda method of taking undercuts including using the above-mentioned take-off assembly in the spiral separator.
