5. 1 SILO
DESCRIPTION:
The silo is made of mdf sheets. Tests showed
that this material is an optimal solution to
prevent static electricity of the small pellets.
Measurements of the silo depend on the desired
capacity of the system. The diameter of the hole
at the bottom determines the flow speed of the
pellets out of the silo. The flow speed does not
depend on the amount of pellets, it remains the
same.
First the mdf sheets have to be sawn and
afterwards fixed to each other by using screws.
It is important to seal up the silo completely with
silicon or putty to prevent unwanted flow of
pellets.
Optional: perspex can be used at the front side
of the silo to make it possible to see the amount
of pellets in the silo.
Sawing machine, drillmachine, spanners
Mdf sheets, screws, silicon/putty are bought
The costs depend on the used materials.
6. 2 SILO COVER
DESCRIPTION:
The cover at the top of the silo is made of a
wooden frame. A cloth is stretched over the
frame and fixed with staples
When pellets are sucked up by using the venturi
system, air also comes into the silo. The cloth is
used to make it possible to let the air escape
without the small pellets
Saw machine, drilling machine, stapler, screws
7. 3 PP VALVE
DESCRIPTION:
A valve is fitted at the bottom of the silo. This
valve makes sure that there is no unwanted flow
of pellets when the system is closed. A
pneumatic cylinder is connected to a mdf sheet
which is fixed on the back side of the silo.
Because of the high forces of the cylinder on the
handle of the valve, the system is strengthened
with 2 aluminum profiles. The cylinder has to be
fixed at an angle of 45 degrees .
At the bottom of the valve is screw thread
provided which is useful when you want to
mount a small nozzle.

SUPPORT STRUCTURE
DESCRIPTION
The silo is fixed with 4 bolts on a metal frame
which is adjustable in height. The frame consists
of square profiles of 40 x 40 x 2 mm and 35 x 35
x 2 mm and is welded.

Metal saw machine, drilling machine, welding
machine, spanners
The metal profiles have to be sawed at the
required length
10. 5 VENTURI SYSTEM
DESCRIPTION
At the top of the silo a hole has to be drilled to
fit the venturi system. The system is fixed on 2
aluminum U-shape profiles which are connected
to the silo. By using bolts and nuts the system is
easily to assemble or disassemble. At the top of
the venturi is a connector to fit a tube. The
suction hose can be fitted on the venturi system.
A clamping ring makes sure that the hose is
fixed.

PRESSURE REGULATOR
DESCRIPTION
The pressure regulator can be fixed on the silo
with a bolt-nut connection. Factories normally
have a pneumatic circuit with a pressure
between 6-7 bar. By using a pressure regulator,
the air flow can be regulated, which makes it
possible set the suction speed for the pellets.

DESCRIPTION:
The final step is fixing the tubes on the metal
square profiles with straps. This step is
important to prevent faltering which could
damage the pneumatic circuit or injure the
person using the styvocontrol
