ABSTRACT:
A mixer for mixing glass fibres into a thick aqueous cement slurry comprises means for feeding glass fibres on to the surface of a batch of the slurry in an upright cylindrical chamber, an agitator mounted on a coaxial vertical shaft and carrying at its lower end both a plurality of short impeller blades and a long horizontal member with tip blades of opposite sense to the impeller blades, so as to cause vertical as well as horizontal circulation of the slurry, and stationary baffles on the wall of the chamber angled to cause production of standing waves on the surface of the slurry.
