Cheap abrasive is the most expensive way to blast.
The US Navy prices blasting by the finished square metre, not the price of a bag. Put your job through their formula and see where the money really goes: abrasive, labour, equipment, and the clean-up nobody prices in.
Same job, same crew. Which one finishes first?
Both plates run in true proportion to your numbers: blasting, the spent abrasive it leaves, and the clean-up after.
Pile size follows tonnes of spent abrasive. The strip under each plate shows blasting, clean-up and set-up time.

How the Navy formula gets there
All line items
Pressure check
The numbers above assume 100 psi at the nozzle. Every 1 psi below that costs about 1.5% of blasting speed. Most crews read the compressor gauge, not the nozzle.
Air and abrasive flow figures are Clemco's published values for new nozzles and 100 lb/ft³ abrasive. Worn nozzles draw more air.
