You want sufficient rotation speed for solution transfer, parts movement, and even exposure of all surfaces for plating, but no more than necessary to limit abrasion and possible parts damage. 4 to 6 RPM is pretty typical for production sized barrels. Did you mean that 24 barrels share a 4000 Amp rectifier, or maybe that each barrel has a 400 Amp rectifier?
