Screw Feeder Experience with Limestone Dust

Screw Feeder Experience with Limestone Dust

Screw Feeder Experience with Limestone Dust

(OP)
I am working on a project to relocate a truck loading chute about 20' from its current position under a storage bin. The client suggested a rotary airlock to screw conveyor to truck loading chute. After looking at screw conveyors I was thinking of screw feeder (eliminate rotary air lock)to truck loading chute. The material is limestone dust.

I talked with a sales engineer who seemed confident the screw feeder would work. I was doing more research online I find very few companies make screw feeders.

Does anyone have experience with long term durability of screw feeders? The initial cost of the two options is the same so the advantage for screw feeder is having one less piece of equipment to maintain.

Check out these guys ,
Just watch out for moisture with lime dust. it is a first cousin to concrete. Whilst their sales literature says non abrasive dust I have used these in the past on fly ash.

You are judged not by what you know, but by what you can do.

RE: Screw Feeder Experience with Limestone Dust

You may be able to find more sources by searching on 'farm augers' - very commonly used for moving bulk agricultural solids. (Also a dangerous piece of equipment, I might add, if not used with caution.)

RE: Screw Feeder Experience with Limestone Dust

Farm Augers would probably be rather light weight for this usage....... talk to the concrete batch plant guys who move millions of tons of cement every year with their augers
