RE:RE:4 PHASE Project ROUTE To COMMERCIAL-SCALE POTASH DRYING I believe the radiated energy / electromagnetic waves will seek out the bi-polar H2O molecules surrounding the ore particles and vaporizing it to its gas form and then air blowing/turbo flowing into the dryer will remove the water vapour.
Commercial dryers I've seen are rolling cylinders, on a decline slope. Cylindars come in many sizes, just long. Ore enters the higher end and egress, due to rotation and gravity, out the lower end onto a conveyer. Heated Air enters one end out the other. Ore is churned in this manner for greater air contact. Some cylinder are shaped, I believe to help air flow (like turbo) better.
But with CTI, I am guessing a simple way to agitate the ore on a conveyer with CTI transmission lines above the conveyer would also work. Air does not need to be heated (?).
IMO I don't think the potash ore needs to capture any energy. If potash ore is transparent to the electromagnetic waves, then all much better.
* it is HOW the RADIATED ENERGY is CAPTURED and TRANSFERRED to the POTASH ORE in an ENERGY EFFICIENT and EXPENSE-SENSITIVE WAY that will DETERMINE the COMMERCIAL FEASIBILITY and SUCCESS of the project
