Way To Go
Hello,
concluding from your post, i'd suggest that you for a first approach a reputed vibrator conveyor supplier in your area and get som brochure on their product range with the rough project calculations. Then, for background, take on some engineering books, or contact a local eng. school, or hire someone with insight to show you.
There's more to it, already beginning with the material properties, pls. try to get more specific informations as going along with design (cane sugar or cristallized sugar, lump / grain size, moisture issues...).
one way might be: http://www.sugarconveyors.co.uk/vibratory.html

Go For It!
What inclination do you need?
Robsons, mentioned by Roland, would be an excellent choice but they are far away from you and wouldn't give much away.
Shaker pans are simple enough. They were very useful in shifting reef from stope faces in gold mines when I was a lad. There the workings were predominantly down dip but I have seen them running upwards as well. We slung a length of fence pile under chains at each corner, fastened it to the hangingwall with roof bolts (Aagh!!) and connected a vibrator underneath. Rock was lashed onto the pan and the chain links were adjusted along with the stroke and frequency to get the reef moving. Shaker pans were arranged along the full 40m stope and fed rock into the scraper slusher gulley. As the name slusher implies the operation was a very robust affair. I doubt sugar cane or bagasse is difficult to handle if you employ the gold mining rationale of suck it and see. Above ground you will need to examine resonance behavior on the parent structure and ensure that the vibro-motor is explosion proof around parts of a sugar mill. Sometimes it is cheaper, faster and more rewarding to find these things out for yourself. In your application Construction Costs and Commissioning mock the expense of Procurement and Shipping. If you can't get the stuff to flow the way you want when all the available variables have been exhausted then neither can anybody else. It's not rocket science to put material onto a shaking pan and see what falls off at the other end. And if all fails you can use the fence pile for...piling, chains are always useful and you were going to buy a variable speed vibro-motor anyway. If it works then your biggest expense will be the supply of noise abatement modules (simply known as ear muffs, or plugs, outside the USA). ■

Go Didyo: A Good Idea
Well, this would be a nice thing to do: to do it yourself.
Personally I like that very much!
On flow: Sugar tends very much to stick and agglomerate, so the surface of the panes should be chosen very smooth, and the parameters of vibro-flow such, that no pockets or standing wave re-impact occur and flow is smooth and sufficiently fast. Moisture control (time of exposure) is of the essence.
As no more info is offered on the original post, I stay with the hint towards googling / library / hiring expertise --> and be it a team of mechanics to put up a do-it-yourself.
Good luck

On a lighter note:
Being CentralEuropean, I already feel the focus of the < State Agriculture and Food Inspection Authority >, that's an interesting life if you receive their undivided attention... ■
Re: Vibrating Conveyor Design
Hello,
The vibrating conveyor has lengthy trough supported by hinged legs from base member, as a parallelogram arrangement. The arrangement remains stable by additional spring supports. The steel trough is oscillated / moved by crank mechanism throw, and accordingly its amplitude of motion (vibration) has fixed value irrespective of speed. The crank mechanism direction of action is set such that it results into forward as well as upward stroke for trough, to create material movement. This direction is at some inclination to vertical.
The purpose of springs is to provide auxiliary support as well as to store gravitational energy during downward movement, and to release it during upward stroke against gravity, and thereby smaller drive and economical conveyor. Also spring system size and stiffness are chosen so that the system natural frequency is close to operational frequency, to avoid its hindrance to drive action.
The flow rate will depend upon chosen oscillation amplitude, frequency and inclination. The designer has to make appropriate combination of these according to application. The conveyor flow rate calculation will need certain empirical data in combination with calculation, because trough movement influence on bulk material gets subdued due to its nature.
Also the designer needs to be well versed to vibration engineering (motion, forces, resonance, tuning ratio, etc. as per engineering textbooks) to decide proper spring support system. The vibrating conveyor can have a spring system of flat plate type, helical springs or torsional springs.
As said above actual and proper design is complex. Well one can also make it without these, because apparently it is a steel trough supported by hinged leg and springs, and moved by crank (all simple items) but such conveyor will be prone to failure or short life or poor performance as per element of probabilities.
You can prepare for this equipment for future requirement, but creating know-how for immediate need could be somewhat difficult.

Vibrating Conveyor Design
Hi all,
I want design vibrating conveyor with capacity of 35 TPH. width and length of the pan 2x12 M for sugar plants.
Can any body suggest me the inclination and eccentricity can be consider. and also suggest me the power calculation for that.
