The moving fl oors are widely used in the wood panel
industry for storing loose materials such as chips,
sawdust, bark and recycled wood. They are very fl exible
systems, easy to implement, that can guarantee good
dosing performances due to discharge screws driven
by frequency converters. The feeding can be carried
out through mechanical conveying systems or directly
by truck. The material is moved toward the discharge
hopper by means of a set of sliding frames located on the
bottom of the silo and controlled via hydraulic pistons.
The extraction is carried out through the alternate
sliding movement of the frames. The hydraulic unit
is equipped with several control and safety systems
against overpressure. The discharge hopper is provided
with a dosing screw, driven by a frequency converter.
The automatic fi lling of the dosing screw is controlled
through a set of level sensors. The material level in the
storage silo is controlled by means of level sensor (radar).
The silo dimensions vary according to the required
volume, however the following design criteria have to
be applied: Sliding frame width = 1.500 mm (silo width
= multiples of 1.500 mm) / Minimum number of frames
placed side by side = 3 pieces (to ensure a constant and
regular extraction) / Average throughput of each single
sliding frame = max. 50 m³/h.

round silos withhydraulic extractors
The hydraulic extractors are usually installed whenever
the process requires more than one discharge outlet, as
it is possible to install several metering screws on the
bottom of the silo. The system consists of a heavy frame
fastened to the bottom of the silo, driven by hydraulic
cylinders. A slider with elliptical shape, moving back and
forth within limited strokes, conveys the material into the
opening in the bottom of the silo. The metering screws,
designed with variable pitch, extract and discharge the
material out of the silo. The extraction of the material
is carried out across the entire circular surface of the
silo. This system can be used for wet and dried material,
chips, sawdust, particles and wood dust. This solution
ensures very low maintenance and low power demand.
Our systems are provided with the following equipment:
Fire-fighting system (water spraying) / Over-pressure
hatches / Radar control for a continuous monitoring of
the material level in the silo and emergency level switches
/ Anti-bridging elements.

This storage unit is equipped with a rotating turret installed
on the bottom and in the middle of the silo. One or two
metering screws, fastened to the central turret and driven
by the turret itself, provide for the material discharge. The
drive frame is fastened to the bottom of the silo and is
driven via hydraulic cylinders. For larger silos the unit is
provided with supporting stiffening beams. Drive units and
bearing housings are installed externally. Extraction across
the entire circular surface of the silo / To be used for wet
and dry material, chips and flakes / Strongly recommended
for wet flakes (dryer feeding), SL and CL particles / The
material is not de-mixed / No maintenance required
inside the silo / Low power demand / Uniform extraction
that avoids bridge build-ups / Very huge capacity range
/ Provided with fire fighting system (water spraying) /
Provided with over-pressure hatches / Provided with radar
control for the continuous level monitoring / Provided with
level switches / Provided with anti-bridging elements.

Circular silo extractors type EXP are usually applied to
extract wooden particles such as: dust, shavings, chips,
rejects and pellets. These machines are the synthesis of
many solutions directed to obtain the highest productiv-
ity / High extraction capacity with lowest installed power
/ Constant and regular extraction, also with fibrous and
hard materials without demixing of extracted flows / Ab-
sence of spontaneous flows inside discharging hopper /
Maintenance possible also with silo full of material / Suit-
able for silo up to 25 m diameter.
technical features
turret
it is a cylindrical frame that supports the extracting shaft
inside the silo. The turret contains the gear motor dedi-
cated to the aforesaid shaft rotation and is connected to
the silo bottom through a big diameter footstep bear-
ing. Upper side of the turret a cover
fixed through a footstep bearing avoid to
transmitting to the rest of the machine
the creeping load. The rotation of the tur-
ret is realized by two identical torque gear
motors, each group transmits the rota-
tion through a pinion directly connected
with the turret footstep bearing.
extracting shaft
the cantilever extracting shaft consist of
a conical pipe with variable pitch spirals; it is supported
only from one side by a heavy bearing installed inside the
turret. External spirals sides are equipped with crumb-
ing teeth highly wear and tear-proof. The extracting shaft
motorization it is an hydraulic motorization, installed out
of the machine, that, through a pump drives the gear
motor fixed inside the turret. The close circuit hydraulic
transmission does not need the installation of any motor
control inverter and permits to have a high torque even
with low working speed.
