Bulk tank trucks 104 are utilized to feed the plurality of raw material silos 30 and also to receive finished mixed product from the at least one finished product silo 40.
As illustrated in Figure 1, the modular mixing plant 10 includes a plurality of the planetary mixers 20 placed side-by-side and across from each other, preferably in a desired grid pattern. The mixers 20 are fed by a plurality of the raw material silos 30, each along a conveyor 26. The mixers 20 output a predetermined mixture to one or more of the plurality of the finished product silos 40 through the pneumatic lines 80.
Preferably, each (but at least one) of the plurality of raw material silos 30 contains one of at least calcium carbonate, glass, slag, and fly-ash, or some other mineral based or pozzolanic material.

in the direction of arrow B, substantially parallel with the first and third sides 14,18 of the warehouse 12 and away from the at least one finished product silo 40. The plurality of mixers 20 output their mixtures through respective tributary lines 82 of pneumatic lines 80 into a main stem river 84 of pneumatic lines 80. The pneumatic lines 80 extend through the warehouse 12 and transfer the mixtures in the direction of arrow A, substantially parallel to the first and third sides 14,18 of the warehouse 12 and toward the at least one finished product silo 40. The pneumatic lines 80 exit the warehouse 12 at approximately the same location (e.g., the same side of the warehouse 12, here the second side 16) and continue to the at least one finished product silo 40.
The bulk tank trucks 104 enter the drive-through alley 42 of the at least one finished product silo 40 to receive the mixture and travel in a direction substantially perpendicular to the direction of arrows A and B, here illustrated by arrow C. Additional finished product silos 40 may be added preferably along a center line 44 and additional mixers 20 may be added along the main stem river 84 of pneumatic lines 80 with their respective pneumatic line tributaries 82 merging therewith. Therefore, expansion of the modular mixing plant 10 is preferably accomplished by extending outward linearly, with additional mixers 20 added in the direction away from the finished product silos 40 (generally in the direction of arrow B) and additional finished product silos 40 added in the direction away from the mixers 20 (generally in the direction of arrow A) .
Preferably, each mixer 20 is capable of outputting in the range of about 250,000 tons through about 300,000 tons of mixture annually. In the plant 10 illustrated in Figures 1 and 2 the preferable output is in the range of about 1.25 million tons through about 1.5
million tons of mixture annually, though plants of smaller output capacity are certainly contemplated (e.g. 100,000 tons ) .
The foregoing is considered as illustrative only of the principles of the invention. Furthermore, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described. While the preferred embodiment has been described, the details may be changed without departing from the invention. For instance, while the present invention disclosure is provided utilizing certain preferred mixing ingredients, this should not be viewed as a limitation on the reach of the present invention. It is contemplated that the modular mixing plant 10 may be utilized in other mixing operations comprising fine and course aggregate and other ingredients .
