Mixing equipment

Equipment for mixing powdered or particulate cement with a liquid, comprising a mobile fluidised storage container for the powdered or particulate cement, the fluidised storage container having a floor, an outlet and an air permeable deck arranged above the floor for supporting the powdered or particulate cement, a blower unit detachably connectable to the container for supplying fluidising air to the container in the space between the floor and deck, said compressed air passing through the deck to fluidise the powdered or particulate cement, a receiver unit independent of the container being selectively connectable to and disconnectable from the container for being supplied with and for accumulating cement from the container, a mixer unit for mixing the cement with liquid, conveyor means for feeding accumulated cement from the receiver unit to the mixer unit, liquid feed means for feeding liquid to the mixer, and pump means from the mixer unit for delivering a mixture of cement and liquid from the mixer unit to a point of use remote from said mixer unit whereby a succession of mobile fluidised storage containers can be connected to the receiver unit while said feeding of accumulated cement ensures a continuous flow of cement to the mixer unit.
