Incline Belt Feeder

A few points that come to mind associated with belt feeders that influence power and material resistance to flow as belt feeder is inclined:
1. Friction between belt cover and material
2. Wall friction between material and skirts - skirt drag and other shape impediments to flow
3. Height, width, length of skirts - skirt drag
4. Noting skirt drag will inhibit inclination
5. Belt Feeder implies a shear zone above the burden height - more drag from shearing material at and above the shear bar
6. Shape of skirt assy - slot tapers vertically and in plan view
7. Moisture and cohesive properties
8. Size distribution of rock - restricting flow at exit
I am sure there are other factors that escape my recall. ■

Yes, a moment too late:
9. Belt feeder speed ■

Maximum Angle of Inclination of Belt Feeders
Hi All
It is common that belt conveyors are angled at less than 14deg.
However, I see in the mobile plant range some items that are inclined at greater angles
eg
Truck Unloading Stations - Flat section and then inclined feeder section at 25deg - OK slow speed
Boom stacker conveyors at 20deg
I am looking at use handling cement clinker, 50mm max and repose angle 34 deg, free flowing where 14 deg inclination is the design guide ven for steel pan conveyors.
I assume that material will not roll back if there is material behind it and the angle is less than the repose angle.
Are there other guidelines / rules of thumb for feeders?
I need something that works well
Thanks
James ■
