3.5. Grinding group assembly / disassembly
The assembly / disassembly operations of any
machine part are performed with the stop ma-
chine and with the plug disconnected from the
socket, or with the sectioning device in OFF.
The
grinding group Enterprise
assembly on the
machine takes place in two phases (in exemplifying
way it is showed the mincer with basic machine.
The phase n. 1 for the grinding group Enterprise is
performed on a working ground following the under
reported order:
• Insert in the pipe union (1) in the order: Archimedean
screw (2), cutting knife oriented as in figure and
inserted in the dragging pivot (3), drilled plate (4)
inserted in the pipe union place (1);
• Screw down and tighten the blockage wheel (5).
The phase 2 is performed on the machine:
• Insert up to the blow the complete grinding group (B)
on the machine (A);
• Tighten the mouth stop knob (C) up to when the
grinding group (B) is blocked on the machine (A);
• Insert the hopper (D) in the machine neck
• In these conditions the machine is ready to work.
The disassembly activities of the grinding group
from the machine are performed following in the
backwards way the assembly phases previously
described, starting from the phase n. 2 passing to
the phase n. 1.
For a plate and knife better improvement and du-
ration it is advised t
o keep them always coupled.
3.6. Grinding group rotation
The operations here follow indicated must be
performed from the machine maintenance man
(skilled personnel in the electric maintenance
field of the industrial machines).
For machines fed with three phase voltage (3
PE AC 400V 50Hz), slacken lightly the blockage
wheel so as don’t make a strong pressure on the drilled plate as for the cutting knife. During the
switching on verify that the Archimedean screw /
grater roll rotates in anticlockwise sense.
If there is an clockwise rotation, switch off the
machine disconnecting the plug, disassembly it,
disconnect two phase conductors and invert them
of position.
