Abstract:
An apparatus for separating a first mixture of substantially granular materials into its constituent parts and then remixing the constituent parts to achieve a second mixture having a desired composition, said apparatus comprising:a. a first density separator which divides the first mixture into first and second flow streams, said first flow steam consisting of a first material having a first controlled density or size and said second flow stream consisting of a second material having a second controlled density or size less than said first controlled density or size;b. a control valve for regulating the exit of said first flow stream from said density separator and for controlling the division of the first mixture into first and second flow streams by the first density separator;c. a first sensor which provides an electrical signal indicative of the rate at which the material within said first flow stream is exiting said density separator;d. a second sensor which provides a signal indicative of the pulp density of the material within said first density separator;e. a first splitter associated with said first flow stream for controlling delivery of said first material;f. an electronic programmable controller responsive to operator inputs and responsive in real time to the signals provided by said first sensor and second sensor which automatically controls said control valve and said first splitter to produce an ingredient having the desired composition and determines the particle size distribution of the first mixture.
