Combines dust diverters

[R_O_M]

Depends on what type of Gleaner you run. If you run a rotary, Hyperise it, ie; do the mods to the cage such as the triangular corner piece, the steep pitched helicals in the thresher section, sweeps on the separation section of the rotor and the extended bars into the discharge area. Toss in the elevator floor mods for better feeding to the thresher and you will also reduce dust. The rotor actually has some fan type characteristics. With material feeding in the front and the blades on the rotor discharge spinning at speed, a lot of air is pushed through the threshing system in a rotary. A lot of the dust problems from the elevator_ header area are because the separation section of the rotor is heavily loaded with material and the air flow is blocked with a feed back effect out of the elevator_ header. A further creator of dust is the tendency of the standard cage_ rotor set-up to grind the thicker, slower moving material up. Keeping a fast flowing, thin, loose mat of material that allows grain to be centrifuged out without grinding the material up by Hyperising as above will probably reduce the dust problem by 75%. Best sites for Hyperisation details is the Hurtt Equipment site; http:__www.hurttequipment.com_hurtt.cfmIJID=8 and the Hyper Mods section of this site.

I've often wondered if a guy made "fan blades" out of steel and attached them to the stars in the rotor if they would create enough vacuum in the feederhouse to pull the dust throughIJ Of course, the CDF rotor is another story - can't do this with an enclosed rotor.

Use to wonder the same thing myself, Tom. Then we got onto this site many years ago and got the info about the build up of material at the left hand end of the rotor and into the discharge area due to the bars ending before the discharge which of course blocked the smooth flow of material into the discharge and prevented the flow of air through the rotor. The very simple solution of course was just extending the rotor bars and helicals into the discharge area to clear the material and a lot, but not all of our dust problems just disappeared. It's got even better with the other Hyperising mods to the rotor and cage since. I suspect that the Bison rotor may be even better as spinning at speed, it has a positive effect of winding material and air through due to it's auger type design. In addition, from my very short look at the Bison, where the paint has worn off seems to show that one of the main effects of the Bison rotor design is to allow the material mat to fluff up into a loose mat between the flights which allows the grain to centrifuge out and reduces the grinding effect of a mat being held against the cage and so dust reduction and an open material mat for grain to move through. If and when we get a good season here, I think Rolf has a Bison on the list of must haves! We still have some dust with the Hyper mods but they are greatly reduced from the dust problems that arise with the standard rotor_cage configuration.

Johnson the outfit that makes the rock guard behind the sickle makes a dust diverter for John Deere conventional combines which have a major dust out of the feeder-house problem. However, I don't see on for Gleaners or other brands.

actually the intake i saw was on the header right above the feed opening with the exit to the right of feeder house where a hyd.driven fan was located.
