Classification: CPC B  E | IPC B  E

Claim 1:
2. The method of claim 1, further including:
the transmitting of step (a) includes the target input value of a slurry volume fraction (Cs-target);
the executing of computer readable instructions of step (f) includes calculating a slurry volume fraction according to the formula: Cs=({dot over (V)}sl−{dot over (V)}fl)/{dot over (V)}sl;
step (g) includes determining difference (ΔCs) between the Cs-target and the Cs; and then
as part of step (h), if the ΔCs is not less than an acceptable slurry density margin of error (ER-Cs), then the central processing unit sends instructions to cause the command signal to further actuate the first valve to incrementally change the {dot over (V)}fl or to cause the second command signal to further actuate the second valve to incrementally change the {dot over (m)}pr, and then the central processing unit repeats steps (d)-(f), and
as part of step (i), if the ΔCs is less than the ER-Cs, then the central processing unit sends an output signal to a display unit of the blender control unit to indicate that the target input values have been achieved.
