4.8 bags/cubic yard x 33 counts per bag = 158 count per cubic yard.
2. AGGREGATE 1: Divide the lbs. of fine aggregate per cubic yard by the count per cubic yard.
1400 lbs. fine aggregate divided by 158 counts per cu. yd.= 8.86 lbs. per count.
GATE SETTING (from graph) 7.6
3. AGGREGATE 2: Divide the lbs. of coarse aggregate per cubic yard by the count per cubic yard.
1624 lbs. coarse aggregate divided by 158 counts per cu. yd.= 10.27 lbs. per count.

— At this point we recommend that you run a 1/4yard yield test. You must have a box that is 114 cubic yard.
You can build one with internal dimensions of 36" x 36" x 9". You start the unit producing concrete. Stop
both the conveyor and mixer at the same instant. Set the 1/4 cubic yard yield box under the discharge.
Start the mixer and conveyor at the same time. Run the unit to the amount indicated
for 114 cubic yard (1/4th of the meter count per cubic yard from step 1). Shut off the mixer and conveyor at the
same instant. The box should be full. It may be necessary to adjust the aggregate gates slightly to adjust
the yield.
