[QUOTE="mbasko, post: 665475, member: 4485"] [URL unfurl="true"]https://www.goldenpipeline.com.au/the-scheme/need-for-the-scheme/dryblowing/[/URL] From the above I gather modern dryblowers were developed from the "winnowing" dry blow method. To me the advent of "mechanical" dryblowers is more efficient due to the added wind from the bellows or blower rather than relying on the natural drift of the lighter material i.e. by using the bellows or blowers more material could be processed at one time (size of operation dependent) & heavier material (but still lighter than gold) can be removed. To match that my thoughts would be you would need a long drop & plenty of natural breeze. [/QUOTE]
