Dogleg
Short/Long Fall Chutes
EN-6
A dogleg may be used to reduce material velocity
and the detrimental effect of variable material
velocity. The dogleg is especially important when a
long fall chute must be used. If the material is
abrasive, the chute should be lined with an
abrasion-resistant material.
A material in-feed chute where the bin or feeder
discharge to flowmeter flowguide fall is less than
0.6 m (2 ft) is referred to as a
chute is ideal because material velocity caused by
< 0.6 m (2 ft.)
gravity is minimal. The chute centerline and angle
should coincide with that of the flowguide for a
distance greater than or equal to the flowguide
diameter (before the flowguide inlet).
long fall chute
A
where the bin or feeder discharge/flowguide fall is
more than 0.6 m (2 ft). The long fall chute is less
desirable than the short fall chute, as material
velocity is increased. Increased material velocity
> 0.6 m (2 ft.)
increases flowmeter component abrasion. Greater
distances after chute angle changes (to settle
material into desirable flow patterns) are also
required.
