Re: Wood Dust Elevating
The cable and disc type conveyor sounds like a god choice.
A flexible screw conveyor and a small vacuum conveying system are aslo possibles. ■
Re: Wood Dust Elevating
We have just been active in the design od several such systems for a composite decking manufacturing line and after evauating several alternatives, chose the pneumatic approach for the wood dust as it was the easiest to contain the dust situation and belived to be more reliable in the long run over the mechanical alternatives. For one of the other "additives" the flexible screw conveyor was recommended.
Each situation is very often "close" to being the same but differences in the equipment location or production program can make the final selection different. Many times the "capital cost" syndrome out votes the "continued operating costs" argument.
An analysis of the pros and cons of each approach with respect to your specific parameters would be a logical step to take. ■
Elevating Wood Dust
Wood dust is likely to be very poor flowing when settled in a hopper, so the hopper design and pick-up characteristics of the elevator is important. The new 'static screw' elevator by Olds Engineering in Australia offers good in-feed features and total containment, and would integrate better with a feed hopper than a flexible screw. ■

I appreciate the help of all the above.
For the record the customer "found" that other divisions were using flexible screw sucessfully . They were prepared to move the bins beside each other so we are delivering to a "pantleg chute"which will choke delivery to one until the second is also full. Since the flexible screws are not being bent & are limited in length, we anticipate good durability.
We looked at the OLDS but delivery was too long & it would require a second horizontal carrying conveyor as well ■
Wood dust elevating
We are involved in a new project to lift 20 ft wood dust from a hopper to two discharge points both receiving but can be independently shut off. As vertical space is very limited we are thinking of cable & disc in pipe system . Volume required is low .23 cubic metres /minute . Dust containment is important. Any problems in going vertical or almost vertical? Any other options for this small quantity -- vibrating screw -- made for this small a flow? ■
