Application
The MultiFlex weighfeeder is used
for accurate weighing and feeding
of bulk solid secondary fuels used
mainly as a fuel for heating of cement or lime producing kilns as well
as boilers at power plants or combined heat and power plants.
The material processed include all
kinds of alternative fuels typically:
RDF
- shredded plastics,
- textile
- paper
- rubber (tire chips)
Biomass
- wood (chips, pellets)
- straw
agricultural waste
Sludge and granulates
- WWTP sludge
- coal sludge
- animal meal
Any mixtures of above listed
BV-D2423GB

Construction
- Self-supporting frame with high stiffness ensuring high weighing accuracy
- Screw trough with twin screws ensuring very steady material flow
- Screw trough with single helix en3
suring high feed rate up to 300 m /h
- Screws used for non-coherent materials (granulates, sludge, pellets)
- Shaft less helixes used for all other
materials (light weigh, lumpy,
stringy)
- Multiple protection against overfeeding in screw trough and hopper

Equipment
The MultiFlex weigtfeeder is designed for continual feeding of bulk
solids. In principle, the weighfeeder
consists of a hopper and a screw
trough. The bulk material is extracted
by the screw trough out of the hopper
and conveyed towards the discharge
with a feed rate controlled via variable frequency drive of the screws.
The screw trough is fitted with two
screws or center less helixes or with
just one 1000 mm helix at the largest
machine. The hopper is equipped
with an agitator ensuring smooth
emptying of the hopper and optimal
filling of the screw trough. Continuous
filling of the screws allows steady
feeding of the
