A briquetting project, for aliuminium chip (swarf). the swarf is from CNC machining centres and is appoximatly 10mm dia curles
This is bulk feed by a feed hopper (3 cuMts) and 150mm screw to the briquetting machine with out any problems
The hopper is loaded via FLT tripping skips (240kgs) onto a vibrating 30x30mm mesh screen (3000X1200MM).
This is to remove the large tooling lugs 20x20 by 40-100mm long which would jam the briquetting machine
The problem is that the screen will not seive the swarf, even with enough vibration and varing frequancies, it seems to be that the mass of the swarf is locking togerther and just siting on top of the screen. If smaller amounts of the swarf or the full load is spead across the full screen, by the same method of loading the screen works well
One posible option we have come up with is placing a coarse screen (50x50mm) above the 30x30mm screen to take the bulk of the weight of the material this would be vibrated with the fine screen
