Kongskilde SUC-E 100 - Conveying Capacity

Conveying Capacity
The conveying capacity depends
on the piping layout and the type of
material to be conveyed.
In the examples the conveying ca-
pacities apply to materials with the
followingspecicgravities:
Specic gravity
Material kg/m
3
Barley .......................................670
Wheat .......................................750
Oats ..........................................500
Rye ...........................................700
Maize ........................................700
Rape .........................................700
Peas .........................................800
The capacities are based on pre-
cleaned material with a moisture
content of 15% (grain, maize and
peas) or 9% (rape). Unclean crops
and higher moisture contents will
reduce the capacities.
The tables on page 8 show the
conveying capacities for barley, rye,
oats and maize with three different
types of standard suction pipelines
and one standard pressure pipe-
line. The tables on page 12 show
corresponding capacities for wheat,
rape and peas.
Each table gives the capacities of
the different blower sizes at differ-
ent conveying distances.
The conveying distance is the total
length of all horizontal and vertical
piping on the suction and pressure
side. The length of suction hose
is included, but bends and suction
head are not taken into account.
If a long suction head is used, the
conveying distance must be in-
creased by 1.5 m. For each exten-
sion there will be a further increase
of 0.65 m.
Pneumatic conveying is based on
the use of atmospheric air to carry
the crops through the pipelines.
Thusfactorsinuencingtheair
condition (temperature, barometric
pressure) will also effect the con-
veying capacity. The capacities
shown are based on a barometric
pressure of approx. 760 mm Hg
and an air temperature of 20 C.
The examples given are only in-
tended as a guide as many other
factors may affect the capacity.
