INTRODUCTION
A Grinder Unit is a type of size reduction
machine. Its primary purpose is to grind
meat, meat by-products, and other similar
products.
The primary grinding components are a plate
retaining ring, orifice plate, plate bushing,
knifeholder with knife inserts, centering pin,
spring or springs, head, feedscrew, hopper,
gearbox, and drive pulleys. In most instances
an electric motor drives the grinder unit.
This unit is mounted on a undermount frame
(as shown on cover) or sidemount frame.
Standard safety equipment includes a belt
guard, a hopper guard, and a plate guard. If a
transition funnel is used, the plate guard is not
required.
It is important that your application, and/or
installation does not render these guards
ineffective. If for any reason you believe these
guards are not adequate, do not use the machine
and call Dixie Grinders Inc. at once. (256) 582-
0477 OR [phone].
This machine was sold for a specific application.
If you are not familiar with the application that
this unit was sold for, check with Dixie Grinders
Inc. before using the machine.
All operators and sanitation personnel should
read this manual and understand it.

SITE CONSIDERATIONS:
It is important that the permanent position of
the grinder unit provides clearance of several
feet behind, to either side, and approximately
eight feet or more in front of the grinder unit.
If the grinder is set on a stand, or leg extensions
are attached, an adequate platform must be
provided to provide safe access to the grinder
unit. It will be necessary to have an approved
platform or device to provide access so the unit
can be properly sanitized, disassembled,
assembled, and maintained. Consideration
must be given to allow for complete service to
the grinder unit.
Platforms should be so designed not to make
the hopper guard, or other guarding,
ineffective. The hopper guard is not a hopper
for holding a large amount of material, it is
designed to keep the operator away from the
feedscrew. If the location of this grinder unit
compromises this feature, special guarding may
be necessary. Consult your Safety Engineer,
Plant Engineer, and O.S.H.A. for all regulations
related to the guarding of this machine.
Only the feedscrew puller and ring lift can be
attached to the grinder unit directly. Do not
use the grinder frame to support other
equipment without prior approval from Dixie
Grinders Inc. The grinder frame is not to be
used as a personal stand, and under no
circumstances should anyone be allowed to
climb on it or use it as a platform. Remember
to Work Safely!
"THE GRINDER HAS ARRIVED"
LIFT EQUIPMENT REQUIRED:
We recommend using a 5,000 pound capacity
fork lift with 48" or longer forks. Do not
attempt to unload the grinder unit from a
commercial van from ground level! Only
authorized and properly trained equipment
movers should attempt to unload the grinder
unit. Remember to Work Safely!
PRE-UNLOADING INSPECTION:
Before the grinder unit is unloaded, inspect the
unit for any damage before unloading. If the
machine is damaged consult your management,
the trucking company, and Dixie Grinders Inc.
before unloading the machine!
UNLOADING GRINDER UNIT:
With the commercial van properly chocked and
secured to the loading dock, and using only
approved and adequate dock plates should any
attempt be made to unload this machine. Lift
only under the grinder frame, never attempt to
pick up a grinder from the hopper or gearbox.
The forks should be long enough to extend
beyond the end of the frame a safe distance.
Unload the grinder unit and all parts that have
been shipped with the grinder unit. Consult the
packing slip to insure that all pieces have been
unloaded.
UNPACKING:
When the grinder has been properly unloaded it
should be placed in a suitable location for
unpacking. The belt guard protector and the
shipping skids may be removed. Remove any
spare parts that may have been shipped in the
grinder hopper. Use appropriate equipment
and appropriate personal safety equipment in
this process. Remember to Work Safely!

UNIT CONTROLS.
Dixie Grinders Inc. does not supply motor
controls, starters, stop/start stations,
disconnects, or other related equipment that is
required to control the function of the grinder
unit.
INSTALLATION:
The machine can be installed in its permanent position
after the skidding has been removed. Use only
adequate equipment and properly trained personnel to
install the grinder in its permanent position. Use great
care in moving this equipment, it is heavy and must
not be tipped, tilted, jarred or jammed into position.
We recommend a 1° slope to allow water to drain from
the grinder unit.
We recommend serious consideration is given
to the location of the start/stop station.
We strongly recommend that additional stop
stations are located where deemed appropriate.
Disconnects that can be locked out should be so
located that employees that have to operate,
service, and sanitize the unit can lock the unit
out. Each employee that has to work on this
machine should be given a lock and key and
trained in proper procedures for LOCK
OUT/TAG OUT!
Please consult with your Safety Engineer, your
Electrical Engineer, and O.S.H.A. for all
regulations related to the controls and wiring
for this machine.
We do not recommend the use of wye-delta or
star delta starters. In some areas this is
required. If your machine must be wired this
way the operators must understand that they
cannot begin to grind product until full power
is supplied to the grinder feedscrew. If there is
product in the grinder hopper before the unit is
turned on, the grinder may not have enough
torque to start grinding in the reduced torque
condition.
Frequency controllers are very useful, but with
the exception of a grinder connected directly to
a pump unit or mechanical deboner, the use of
a frequency controller on a grinder unit is
usually not necessary. We do recommend a
frequency controller or some form of speed
control is used to feed the grinder, and often to
take the product away from the grinder.
We do not recommend remote operation of any
grinder unit unless special precautions are
taken, and that all possibilities of employee
injury are eliminated.

DISASSEMBLY TOOLS:
If the grinder is not located on floor level
make no attempt to disassemble the grinder
unit without an adequate platform or
provisions provided by the installation
contractor, plant engineer, or plant safety
officer. The grinder has many parts that
have square edges and cutting edges.
Adequate safety equipment should be used
at all times!
After the grinder has been installed in its
permanent position, it can be disassembled.
The tools described below are for both
disassembly and assembly of the grinder
unit.
The end of the ring wrench fits into the end
of the feedscrew and it can be used to
engage the feedscrew to the drive spline.
Plate Lifter
This is used to
remove the plate
and bushing from
the grinder unit, or
on assembly to
install the plate and
bushing into the
grinder unit.
Note:
Wear appropriate safety equipment and
remember to always "Work Safely".

Ring Wrench / Worm insertion tool
The Ring Wrench fits over the lugs of ring and
is used to loosen the ring (counter clockwise),
or tighten the ring (clockwise)
When the grinder unit has been properly
secured, disassembly can begin.

Dropping the ring on the end of the pin will
damage the threads each and every time. There
is no maybe, the threads are damaged and they
need to be fixed. Trying to screw a damaged
ring or chamber ring onto the head or the next
chamber ring will destroy the mating threads
making the mistake a bigger one, now costing
over twice as much to fix.
With the grinder unit properly secured,
disassembly can begin.
Step 1. Using the ring wrench, loosen the ring
by exerting downward pressure, as shown,
turning the ring counter clockwise.
GRINDER UNIT DISASSEMBLY:
READ AND UNDERSTAND THE
FOLLOWING TAG.
Use the ring wrench only to loosen the ring.
When the ring can be turned by hand,
discontinue using the ring wrench.
When the ring has been loosened, turn it off
by hand. Depending on the ring type, the ring
may weigh up to 65 lbs. If this is more than
you can lift, get help. Use the ring remover if
your machine has been equipped with one. Do
not attempt to remove the ring if you are out
of position, or if the ring is higher than the
center of your chest, or if you cannot lift this
much on your own!

Step 2. Remove the #10163 slip in bushing
from the 2nd plate. You may use the plate
remover or carefully use a screw driver. Do
not, under any circumstances, bump the
grinder on to remove the last plate and
bushing. The power should be locked out and
remain locked out during grinder
disassembly!
Step 3. Remove the 2nd plate, #10164 X
5/32".

Step 4 continued, removing 2nd knifeholder.
Step 4. Remove the 2nd knifeholder, #2441.
The #2440 inserts are sharp so be carefull. If
necessary wear gloves.

Step 5. Remove the 2nd set of washer
springs, #2578.
Step 3 continued. It may be necessary to
wiggle or rock the plate in order to remove
it.
