Abstract
An apparatus for mixing and pumping slurry which is mixed with a refractory aggregate material in a gunning nozzle, characterized in that the apparatus is provided at its upper portion with a slurry mixing apparatus and its lower portion with a pumping apparatus which feeds the slurry under pressure by pump. The mixing apparatus includes an opening at the bottom thereof for the downward discharge of the slurry from the mixing apparatus. The pumping apparatus includes an opening at the top thereof positioned directly below the discharge opening of the mixing apparatus for delivering the slurry to the pump, thereby allowing the regulation and pumping of the slurry to be carried out simultaneously. The slurry is pumped to a gunning nozzle for admixture in a predetermined ratio with refractory aggregate.
