INTRODUCTION
The “SINCRO” PLANTS Mod. 750 C have been projected in such a manner as to be able to
granulate and separate materials having different specific weight.
The main applications are as follows:
•Recovery of electric cables (granulation and separation of copper or aluminium from insulating
material like plastic, rubber or paper – with a suitable modificatio - …);
•Granulation and separation of plastic matters from foreign bodies (metals, stones, sand, wood,
glassfibres, synthetic fibres, paper, etc…). It is self-evident that the stones or the metals must
have a reduced dimension.
DO NOT INTRODUCE HARD METALS SUCH AS IRON, STEEL, BRASS...INSIDE THE
MACHINE. THEY CAUSE DAMAGE TO THE CUTTING CHAMBER.
WARNING: IT IS EVIDENT THAH THE STONES AND THE METALS SHOULD
HAVE A SMALL DIMENSION.
WARNING: THE MACHINE MUST WORK IN A CLOSED AND DRY AREA,
WITHOUT HUMIDITY, AWAY FROM DUST AND WHATEVER ATMOSPHERIC
AGENT.

DESCRIPTION OF THE “SINCRO” PLANT MOD. 750 C
The machine consists of one body made of steel plate 5 mm. thick complete with two slots where
the forks of the fork-lift truck are inserted (Page 5 – Fig. 1).
The plant is composed of:
•A granulator mod. 4070 with 5 rotating knives and 2 stationary knives, seated on the body;
•A pneumatic conveyor with negative pressure for the conveyance of the material from the
granulator to the separator. It si made of an electric fan that is placed inside the body and of one
decantation cyclone and a rotary valve placed on the separator.
•A dry – separator housed inside the body;
•A de – dust system composed of a cyclone and a filter with reverse jet cleaning, with a closed
circuit (without emissions in the atmosphere) and housed on a watertight chest of drawers. It is a
part of the body;
•An exhaust fan with bags for the cooling of the cutting chamber (Page 4 -Fig. A).

TRANSPORT AND LIFTING (LOADING AND UNLOADING)
The “SINCRO” plant Mod. 750 C should only be handled and lifted using a forklift truck. The forks
must be inserted in the two slots of the base (Fig. 1 –Page 5).
NOTE: Do not move the machine with other methods so as not to cause any damage.
The forklift truck must have a minimum capacity of Ql. 40 and forks with a minimum length of
2000 mm.
Since the dimensions of the machine obstruct the view of the operator that handles it, another
person should direct him.
Qualified personnel only should carry out the operations of handling, loading and unloading.

INSTALLATION OF THE “SINCRO” PLANT MOD. 750 C
Place the plant entirely in contact with the floor. The machine does not require to be fixed or
anchored.
Provide a minimum space of m. 1,5 round the machine for the cleaning and maintenance and m.2 in
front of the machine so as to remove the separating table.

ELECTRICAL CONNECTIONS
The electric board is already connected with the electric engines.
Select a cable of suitable length and dimension to suite the installed power. Insert the cable into the
hole of the base (See Page 5 – Fig. 1).
Authorised personnel only should carry out the connection with electrical power.
See the wiring diagram inside the use and maintenance manual.
After having connected the machine to the power line, check that the direction of the rotation of the
motors is that indicated by the appropriate arrow on the motors.
If the direction of rotation is reversed (reverse rotation), invert the two phases on the power supply
cable.
PNEUMATIC CONNECTION
Connect the compressed air pipe with the filter (the maximum pressure of operation is of 6 BAR)
according to the directions of the label placed on the filter (Page 7 – Fig. 2).

STARTING
It is recommended to open the cutting chamber and check that no foreign bodies have entered into
the machine during the transport and the installation.
NOTE: Before carring out any maintenance on the cutting chamber, the operator must put on
sufficiently thick working gloves to prevent injury to hands if he accidentally touches sharp
parts or the cutting edge of the blades.
CARRY OUT THE FOLLOWING OPERATIONS WITH THE MACHINE SWITCHED
OFF.
The operations to carry out are as follows:
A. Switch off the power to the machine from the main panel.
B. Unscrew the locking screw ( Page 9 - Fig. 3 ) and open the front door.
C. Open the rear door ( Page 9 - Fig. 4 ).
D. Remove the unloading hopper.
E. Slacken the two knobs and open the grid’s support. Support the grid’s support with one hand in
order to place it slowly on the base.
F. Remove the grid, allowing it to slide on the support, and lift it out.
G.Remove the grid’s support.
H.Open the hopper by turning the proper screw placed on the left high side of the cutting chamber
(Page10 –Fig. 6) and using the proper key supplied.
I. Check that there are no foreign bodies inside the cutting chamber.
J. Close again the hopper.
K.Assemble again the grid’s support, the grid on the support, lift the whole and tighten it by the
two knobs, taking care that the grid slides perfectly into its seats.
L. Remove the right crankcase cover ( Page 10 - Fig. 7 ) and by a manual operation on the pulley,
make one complete revolution of 360° of the rotor in the direction indicated by the appropriate
arrow. If no particular noises or friction are heard, the cutting chamber is completely free.
M. Replace the right crankcase cover .
N. Insert the unloading hopper.
O.Close the rear door by tighting the two knobs.
P. Close the front door and tight the loking screw (Page 9 –Fig. 3).
Q. Give again tension to the electric board of the machine.

After completing all the connections, check the functions of the machine and operate it idly: first
start the aspirator and then the other machines in this order: vibrator, the rotary valve, the fan and
the grinder. Switch off the machine following the reverse order: the grinder, the fan, the rotary
valve, the vibrator and the aspirator.
Switching on the power, the cleaning system of the filter starts automatically.
Wait for about 20-25 seconds, which is the time required for the electric motor to reach maximum
power.
