Claim:
An apparatus for securing a proper mixing of a particulate material into a liquid, comprising: a storage tank containing mixture of liquid and a particulate material; a pump for circulating the mixture of liquid and particulate material; a plurality of nozzles each having a smaller cross sectional area at its outlet than at its inlet, the mixture of liquid being pumped through the plurality of nozzles and producing liquid jets meeting each other; pipelines associated with the pump and transporting said mixture of liquid from the storage tank through the plurality of nozzles and back to the storage tank; and a further pipe arranged downstream of the plurality of nozzles and extending down into the storage tank such that a lower end of the further pipe is completely submerged into said mixture of liquid; wherein the plurality of nozzles are arranged in a pipe of the associated pipelines downstream of an outlet from the storage tank, each nozzle of the plurality of nozzles having a center axis which converges towards another center axis of another nozzle of the plurality of nozzles, so that the liquid jets of the mixture of liquid meet in one single theoretical point downstream of the plurality of nozzles.
