Claim:
Apparatus for producing a clay slurry from a super bag of raw clay in a substantially dust-free manner, comprising: a water-driven vacuum eductor having an inlet port adapted to be connected to a source of pressurized water, a suction port, and a discharge port, means for breaking the suction at the suction port, a frame including a head supported by a plurality of legs sized so that the frame can support a super bag of raw clay such that its weight may be continuously monitored, said frame including a winch with a lifting device for lifting and suspending the super bag of clay, a load cell coaching with the winch and lifting device for continually monitoring the weight of the clay, a clay feed line connected to said suction port of the eductor and extending into the clay in the bag, a bag shaker in said clay, and a programmable logic controller for controlling the feed rate of the clay, said controller having an input for receiving a weight signal from said load cell, an output for controlling the means for breaking the suction, and an output for controlling the bag shaker, whereby the controller after being set controls the feed rate of the clay to the eductor at a substantially uniform feed rate to continuously provide said clay slurry to an end use point.
