Yes. Feed gradations and crusher output gradations can be modified under adjust setup, and actual gradations can be added using "Sample Buckets" on flow lines. For any end product, the measured gradation can be added to show the comparison to calculated. Measured rates can be added, but AggFlow will use the calculated in a simulation to ensure mass balance between feed and product rates. You can customize the program to simulate your plant almost perfectly. This allows you to establish a benchmark for the plant and then define the effects of equipment or process changes with extreme confidence and accuracy.
