Figure 36: Example Calculations of a 5-component blend in “Quickset” mode
Virgin (NAT): ???
Additive1 (ADD): 5.00% - of virgin component
Regrind (RGD): 30.00% - of total batch
Additive2 (ADD): 2.00% - of virgin component
Additive3 (ADD): 1.00% - of virgin component
Batch Size: 10.00 lbs.
Total available: 100.00%
Regrind: 30.00%
Balance: 70.00%
Virgin + Additive 1 + Additive 2 + Additive 3 = 70.00%
Virgin + (5% of virgin) + (2% of virgin) + (1% of virgin) = 70.00%
Virgin + (5/100 x virgin) + (2/100 x virgin) + (1/100 x virgin) = 70/100
100 virgin + 5 virgin + 2 virgin + 1 virgin = 70
108 virgin = 70
Virgin = 70/108 = 64.81%
Virgin = 64.81% of batch
Additive1 = 5% of 64.81% = 3.24% of batch (5% of virgin)
Regrind = 30% of batch
Additive2 = 2% of 64.81% = 1.30% of batch (2% of virgin)
Additive3 = 1% of 64.81% = 0.65% of batch (1% of virgin)
Virgin + Additive 1 + Additive 2 + Additive 3 + Regrind = 100%
64.81% + 3.24% + 1.30% + 0.65% + 30.00% = 100%
