The Metalfab Model APB Volumetric Belt Feeder is a ruggedly
built slider bed assembly designed for the highly accurate
metering of all types of powders, pellets and agglomerates.
The unit is exceptionally well suited for the feeding of abrasive
materials and those which have a tendency to smear or compress
when being fed by a volumetric screw.
In addition, the APB feeder is ideal for the high volume requirements
of the chemical and food industries. Normal metering accuracy
is +/- 1 to 1 1/2%
Standard APB feeders are available with belt widths of 12",
24", 36" and 48" and in belt lengths of 36",
72", 108" and 144" respectively.
The largest units are capable of achieving rates of up to
4,800 cu. ft./hr. simply by increasing the speed of the belt,
which is driven by an S.C.R. controlled DC motor.
Although neoprene belts are standard, other compounds, such
as Hy-car, Nordel and Viton are also available, as are specially
coated materials. Bearings are sealed and located outboard
to prevent contamination, and all units are equipped with
skirtboards and adjustable belt take-ups.
Belt scrapers, which help prevent build-up of materials on
the belt surface and ensure complete discharge of material
from the belt, are standard.
An optional, manually-adjusted nozzle which can regulate the
depth and width of material on the belt in order to help maintain
a continuing high degree of accuracy is also available. The
nozzle may be attached to the outlet of the static bin when
feeding free-flowing materials, or to the outlet of a Metalfab
Bin Activator, for
difficult materials. |
