Designing Vibrating Chute

Thanks for this opportunity to post this question. I would like to construct a 48 inch wide flat bottom chute, built out of perhaps 1/4 in steel plate. The length is to be about 8 feet. The slurry conveyed will be 56 tons per hour of minus 1 1/2 inch (38 mm) rounded quartzite gravel sand together with 27,000 gallons of water per hour- a 33% solids by weight slurry. The sand is well graded and includes between 5 and 10% of minus 200 mesh clay. The reason for such a wide chute- the reduction of velocity and stratification of the sand helps the machinery that follows.

Now the problem- I would like to make the slope of the chute perhaps 1/2 inch per foot downhill in the direction of flow. I'm quite sure that this will require vibration to move the material along.

Now the question- does anyone have ideas about how many pounds of centrifical force a vibrator would require to move this slurry? Any other ideas to move this slurry along?

Thanks, Bob Ostlund

Hello Bob

Check out the following link. They have many online application manuals that you will find interesting. If you cannot come up with your answer from there then I am sure a rep from Vibco will contact you if you ask them to.

Moving Slurry Along

Try to keep slope of chute at natural angle of repose of the material being slurried along the chute.

MORE GRAVITY is better, steeper vs shallower.

line BOTTOM of chute with UHMW .........more slippery

Like gary says......keep moving with vibrator to help flow

INSTALL small water line at top end to help slurrify and avoid ganging up in chute or flume.

................

QUESTION: are you going to try and take out the 200's later in the process............if so, how?

Gary, thanks for the online Vibco manual. Very helpful- also good mounting information for vibrator.

George, thanks for reminding me about the use of UHMV polyethelylene. I am currently moving this pulp in a 12 inch steel pipe at approx 4 inch per foot slope. This works well to move the sand, but the discharge is quite violent. From this pipe the pulp is distributed onto jigs. I thought that the use of a rather flat and wide chute would permit the pulp to be fed directly to the jigs without a boil box.

George, you had asked me about taking out the 200 mesh. This is a placer operation, so all the pulp ends up in the tailing pond without further size separation

Thanks Bob Ostlund
