Automated Blending

Automated Blending System

“Example of Flow Control Technology”

Multiple CFS Density Separators and Autogates being controlled by a PLC. CFS blends fine and coarse fractions together in wet high percent slurries. Flowability of wet slurries are much more consistent than damp sticky sand fractions blended after the fact. CFS uses both Blend on the Run and Flow Control Technology to produce the most accurate blended sands in world.                                                          Patent Design Pat.#7380669

Blend on the Run™ Technology


Automated Blend Gate Interface
Example of Blend on the Run™ Technology

CFS single tank blend system based on coarser or finer gradation Autogates are automatically adjusted by CFS’s patented PLC system controls.

Density Separator PLC Interface

Density Separator is a particle analyzer which measures coarser and finer feeds as they happen.

CFS uses the Density Separator instrumentation input to change the rate of blend on a real time basis.
