1 chamber to 1 press (1:1)
1 chamber to 1 press (1:1) makes 20 kg/min of moonstone and draws 28 kW. Here is the sand balance, what the published sources say, and what Foundry's solver builds for the same output.

Sand balance
1 chamber make 25 kg/min of sand at full speed (1 x 25). 1 press use 10 kg/min (1 x 10). That leaves 15 kg/min of spare sand, so the chambers run below full speed or the surplus is sold.
What the Foundry solver builds
Asked for 20 kg/min of moonstone, the solver sizes 1 Pressure Chamber and 1 Stone Press, with 20 kg/min of dust, 28 kW and $2,120 in total (machines, solar panels and placeholder belts). It agrees with the published ratio.
The 1:1 dust to sand yield is displayed by two databases and not formally proven by the specifications.
