ABSTRACT:
A mixer for mixing glass fibres into a relatively dilute aqueous cement slurry, e.g. for use in forming glass fibre reinforced cement products on an asbestos-cement making machine of the Hatschek or Bell type, comprises an annular chamber with a tangential slurry inlet, a helical rising floor, a coaxial conical outlet disposed to receive slurry flowing over the inner wall, which is lower than the outer wall, and a fibre inlet above the conical outlet so that the fibres are mixed with the slurry as it passes down the wall of the conical outlet in a vortex motion.
