1. A control method for continuously mixing at least two materials, comprising the actions of:

  • (a) controlling the relative proportion and total flow rate of two materials entering a continuous mixing process to thereby achieve a desired total flow rate and a desired density of the resulting mixture;

    wherein said materials differ in density;

    (b) maintaining an estimate of the expected density of said mixture;

    (c) measuring the actual density of said mixture; and

    (d) when said actions (b) and (c) produce inconsistent results, temporarily reducing said total flow rate.
