ABSTRACT:
Apparatus and method for producing a slurry. The apparatus includes a slurry reservoir, a closed circuit and a pump for circulating slurry from the reservoir through the closed circuit and back to the reservoir. Means are provided for introducing both particulate and liquid materials into the closed circuit for forming the slurry. A first control circuit provides a particulate flow rate signal indicating the rate of flow of particulate material into the closed circuit. A flow meter provides a liquid flow rate signal indicative of the actual flow rate of liquid material into the closed circuit. A density measuring and control circuit measures the density of slurry flowing within the closed circuit and provides a density signal indicative of the difference between the measured density of slurry and a desired desity based upon data inputted to the density measuring and control circuit. A ratio circuit, receiving the particulate flow rate signal and density signal generates a desired rate of flow signal indicative of a desired flow rate for the introduction of the liquid material into the closed circuit. This desired rate of flow is a function of desired slurry density, actual density and the particulate flow rate. A liquid control circuit receives the desired rate of flow signal from the ratio circuit and the liquid flow rate signal from the flow meter and generates a feedback signal for controlling the actual rate of flow of liquid material into the closed circuit to maintain precise control over the actual density of slurry in order to achieve the desired slurry density.
