[QUOTE="Geo2, post: 306995, member: 4572"] Here is an update: A Sudanese man has made a portable dry blower similar in concept to the Aussie's one I mentioned in my first post video "gold digger, australian made" . He tried to fix the issues found in the commonly used dry blowers in Sudan , most of which are local made. They consist of large hopper attached to it several Keene style "dry washer" boxes. Constant air supplied using a big fan powered by a Lister type engine. Although simple to make and operate , these dry blowers suffer from several issues, including immobility of the machine and when wind changes direction the whole operation stops :( Here are two videos, first one shows how "traditional" dry blower is run: They call these large dry blowers "Sieves" :D : [video=480,360][url]https://www.youtube.com/watch?v=8R7u7JL4CUI[/url][/video] The second video shows the machine I mentioned above, complete mobility but sure there is always places for improvements : [video=480,360][url]https://www.youtube.com/watch?v=eAOs4O6Hc4c[/url][/video] [/QUOTE]
