Description
3.1 Material feed examples
Long fall chute
① > 0.6 m (2 ft)
Dogleg
Deadbox
16
• material in-feed where the bin or feeder discharge/flowguide
fall is more than 0.6 m (2 ft)
• less desirable than the short fall chute because material
velocity is greater, increasing flowmeter component abrasion
• greater distances after chute angle changes required to settle
material into desirable flow patterns
• used to reduce the detrimental effect of high or variable
material velocity, especially when using a long fall chute
• for abrasive materials, line the chute with an abrasion resistant
material, or use an in-feed deadbox
• installed where the chute angle changes. This will cause the
material to impact upon itself, rather than the chute surface.
• used when the feeder discharge velocity is high, variable,
where long fall chute angles change, and if the material is
particularly abrasive
