How to Calculate Slope (Degree) to Convey Plastics Pellet

You should know gravity. That's what makes things go down.

Gravitation - Wikipedia, the free encyclopedia

took the words right out of my mouth!

I've never heard of that technique before, but it makes perfect sense.

I'll add a GA for you. Nicely done, and congratulations on becoming a CR4 Guru!

Das Boot is for you!

Never would have thought of that, Great answer!

The angle of repose is determined, to a great extent, to the shape of the articles. Whereas the slope that they will slide on is determined by co-efficients of friction unless the pellets are spherical or close to it.

So the angle of repose will not necessarily give you an answer.

As someone suggested, you can theorise to your heart's content but sooner or later you must suck it and see.

Hi PennPiper,

Add my congratulations on reaching GURU.

Best regards,

If there is a reason for the items not travelling down the slope, flattish sides,
friction, low mass, whatever.. you could give them additional impetus by letting
them free fall for a short distance before landing on and using your slope?

Then you could angle the slope to ensure that the momentum they have acquired
is just enough to reach their destination? This may shorten the required slope?

Hope this helps. jt.

What's E T short for ? ...... Cos he's only got little legs.

Crime on multi storey car parks....it's wrong on all levels.

What we need to know to more fully understand your application would be greatly helped by one or more photos, one or more diagrams, and at least two more bits of information, in order to get an idea of about how much slope is involved...

1. About how far downward do the pellets have available to directly travel to the pellet classifier? ( i.e.: /\y = ? )

2. About how far laterally do the pellets have available to directly travel to the pellet classifier? ( i.e.: /\x = ? )

3. The net available slope, in percent, would then equal: 100% x ( /\y / /\x )

Consideration of relevant technical details, like whether the pellets come out of cutting hot enough to stick together and thereby possibly foul the flow, etc., would then be taken into account, and addressed effectively.
