1. Introduction
This manual is for CONAIR MAR TIN's 79 series granulators. The
abbreviations mean:
-B = Band conveyor -U = Suction blower
-L = Low level -V = Ejector (Air V eyor).
The manual should be studied carefully before installing and using the
equipment, in order to prevent personal injury and damage to the machinery .
Always take great care when the knives are within reach,
since they are very sharp and can cause personal injury.
CONAIR MAR TIN granulators are built for granulation of injection moulded,
blow moulded or extruded plastic waste where the granulator’s size and
performance corresponds to the type of waste. For any other products or
materials, approval must be obtained from the dealer or head-office in order for
the conditions of the guarantee to remain valid.
CONAIR
The different types of granulator are designed so that maintenance and cleaning
can be carried out quickly and simply , both during routine maintenance as well
as when changing colour or material.
All servicing work should be carried out by a person with technical training or
corresponding professional experience. The manual contains instructions for
both handling and servicing the granulator . Chapter 7, which contains servicing
instructions, is intended for service engineers. Other chapters contain
instructions for the daily operator .
Delivered with the granulator are a manual, tool kit and touch-up paint.
Any modifications, changes, or rebuilding of the granulator must be approved
by CONAIR MAR TIN in order to avoid personal injury and damage to
machinery and to ensure that the documentation remains correct.

The granulator is controlled from an electrical cabinet with a start/stop function
and an emergency stop button.
The material is fed into the hopper (A) and falls down to the rotor. The rotor’s
knives (B) grind the material against the fixed knives (C) in the cutter housing.
Both the fixed and rotating knives can be changed or re-sharpened when
necessary . The sharpening is carried out in a special fixture outside of the
granulator .
Under the rotor is a screen (D) through which the granulate passes before it
comes down into the granule bin. The screen is available with various hole sizes
depending on the required degree of coarseness of the granulate.
The granulated material is then collected in the granule bin (E). The standard -L
model is fitted with a suction pipe. The -LBU is fitted with a suction blower
which sucks the granulate out of the granule bin. The -LBV is fitted with an
ejector (air veyor).
The granule bin, screen and screen box are designed to be removed so that the
rotor can easily be cleaned. The hopper is constructed so that it can be opened
up to allow improved access for cleaning and maintenance.

CONAIR
3.2 Safety system
Since there are rotating knives inside the granulator, there is a built-in safety
system to prevent personal injury .
Emergency stop: The equipment is fitted with an emergency stop switch on the
electrical cabinet. The emergency stop is activated by pushing the button. It is
reset by turning the button in the direction of the arrow (anti-clockwise).
Safety switches: The safety system includes 2 safety switches. The switches are
located as follows:
• 1 by the hopper
• 1 by the screenbox
The system is designed so that you have to unscrew the break screw by the
screenbox to be able to open it. The break screw actuates the safety switch,
which cuts off the power so that the rotor stops before the screenbox can be
opened.
The hopper must be lowered and locked before the granulator can be operated.
The safety switch has been installed so that it is not possible to start the
granulator when the hopper is open.

4. Safety regulations
4.1 Overview
The granulator is equipped with safety switches to prevent the front door and
the hopper from being opened during operation.
The following safety measures should always be observed when handling the
granulator:
• Always switch off the power supply using the main circuit-breaker (on
top of the electrical cabinet) before opening the granulator.
• Never put any part of your body into any openings on the granulator
unless the main circuit-breaker is in the "OFF" (=0) position.
• Always be careful when the knives are in reach since they are very
sharp. When the rotor has to be rotated manually, this must be done
with the greatest care!
• Be careful when the hopper and screenbox are opened and closed so
that no part of your body gets caught.
• The granulator cannot be started until the doors and the hopper are
locked.
4.2 Sound level
• Equivalent continuous A-weighted acoustic pressure level 79 = 83.6 dBA
Value measured 1 m from the surface of the machine and 1.6 m above the
surface of the floor during grinding of 5 litres of PE bottles (polyethylene).

5. Installation
All instructions must be carried out in the order described, to prevent personal
injury or damage to machinery .
Always take great care when handling the knives since they ar e
very sharp and can cause personal injury.
The granulator should be connected to the mains supply by an
authorised electrician.
5.1 Pre-start checks
• Before the granulator is installed, the rust preventive should be carefully
cleaned from the parts which are not painted or rustproof.
5.2 Opening and closing the hopper and screenbox
Screenbox:
1. Unscrew the star knob (A) and pull out the
granule bin (B).
2. Unscrew the breakscrew (C) until the door's
stop plate is released. A safety switch is then
activated, which cuts off the current to
prevent the machine from being started when
the screenbox is open.
3. Loosen the nuts (D).
4. Raise the link screws (E).
5. Lower the screenbox and lift out the screen.
NOTE: When mounting the screenbox the link
screws' nuts (D) must be tightened quite
hard to avoid only one of the link screws
taking the whole load. Tighten them quite
hard so that the break screw turns easily.

6. Operation and daily maintenance
6.1 Starting and stopping
The start and stop functions are controlled by a change-over button on the
electrical cabinet.
NOTE: The granulator should not be stopped until it has finished grinding all
the material in the hopper and cutter housing. Any remaining material can slow
down the rotor when it is re-started which can overload the motor and trigger
the overload protector. (See 6.4)
6.2 Inspection
There should not be any material in the granulator when the inspection is to be
carried out.
6.2.1 Daily inspection
• Flaps in the hopper. Check that the flaps are not damaged. Damaged parts
should be replaced immediately to prevent bits of the flaps from falling into
the cutter housing and damaging the knives. There is also a risk that
damaged flaps can be thrown back by the machine.
• Emergency stop. Check the emergency stop function by starting the
granulator and then stopping it using the emergency stop button. The
emergency stop is reset by turning the emergency stop button in the
direction of the arrow. The machine can then be re-started by pressing
“START”.
6.2.2 Weekly inspection
• Cables. Inspect all cabling in the machine to see that there is no wear or
other damage. For reasons of personal
protection, damaged parts should be replaced
immediately.
• Safety switches. There are two safety
switches, one for the screen box and one for
the hopper:
Screenbox: Check the safety switch by starting
the granulator and then unscrewing the break
screw (A) on the bottom of the belt guard, as
described in chapter 5.2. The granulator should
have stopped before you are able to open the
screenbox.
A
Hopper: Open the hopper as described in chapter 5.2, but close and lock the
screenbox. Check the safety switch to the hopper by starting the granulator . It
should not be possible to start the granulator until the hopper is lowered and the
break screws are screwed in.

very sharp and can cause personal injury.
1. Open the hopper and screenbox as
described in chapter 5.2.
2. Clean the hopper, flaps, screen and
screenbox and granule bin.
3. Clean the cutter-housing and inside the
stand.
4. Replace all parts in reverse order.
NOTE: When mounting the screenbox the
link screws' nuts (A) must be tightened quite
hard to avoid only one of the link screws
taking the whole load.
A
Note: Steps 2 - 4 should be carried out every time the machine is cleaned,
or at least once every 300 hours.
6.4 T rouble-shooting
6.4.1 If the granulator does not start
• Check that the saftey switches’ break screws are turned fully clockwise. It is
not possible to start the granulator unless the break screws are screwed in.
• Check that the emergency stop is not activated. It can be reset by turning the
button in the direction of the arrow.
• The bimetal relay F1 in the electrical cabinet,
according to the diagram opposite, is
released if you press stop or overload the
granulator. This is indicated by the small
green rectangular pin (P), which sticks up
above the surface of the bimetal relay. When
you reset by pressing the "Reset" button, the
pin (P) is pushed back in so that it is level
with the surface of the bimetal relay.

CONAIR
7.2 Sharpening the knives
Always take great care when sharpening the knives since they
are very sharp and can cause personal injury.
7.2.1 Overview
NOTE: Use the services of a skilled person when re-sharpening the knives
and only sharpen the edges marked with the special sign! (see diagram
under 7.2.2 and 7.2.3)
The knives must be sharpened so that the correct grinding angles are obtained,
otherwise the granulator will not operate effectively with lightly cutting knives.
During sharpening, the knife must be cooled the whole time with plenty of
water and must definitely not burn or start blueing on the edge since this means
that the knife lacks durability and stability . If this occurs, the knife cannot be
repaired by further grinding down or grinding away of the blued or burnt
colour. The tempered knife may have deep deformations with possible cracking
as a consequence.
The following instructions apply only if you are using CONAIR MARTIN's
sharpening fixture 79. The sharpening fixture is intended for use in a surface
grinding machine and should be fixed on a magnetic board.
7.2.2 Sharpening the fixed and rotating knives
Fixed knives:
Regarding the third fixed knife, see chapter 11.
NOTE: Only the surfaces marked with the special sign should be sharpened.
The specified measurements apply when sharpening the knives.
• The fixed knives are fastened as shown
in the adjacent figure, left part, and the
cutting angle is sharpened at 200.
• The knives can be sharpened only as much as is
shown in the adjacent figure. After that, they are
worn out and should be replaced by new ones in
order for the granulation to be effective.
05-15-96 79 14
Page 15
CONAIR
Rotating knives:
NOTE: All rotating knives should be sharpened equally so that the cutter does
not become unbalanced.
• The rotating knife is fastened
with the stirrup (A) under the
lower part of the knife, as shown
in the adjacent figure, right part.
Ball washers should be used
when tightening. In this position
the relief angle is sharpened.
• Loosen the screws and remove
the stirrup (A), fasten the knife
again. In this position the cutting
angle is sharpened.
• The knives can be sharpened only as
much as is shown in the adjacent
figure. After that, they are worn out
and should be replaced by new ones
in order for the granulation to be
effective.

8.1.6 Pause/pulse relay when emptying with air veyor
In those cases when emptying of the granule bin with an air veyor has been
chosen, the pause/pulse relay should be cancelled to prevent a glut in the
granule bin.
When delivered, the relay is preset
as follows:
T1 = range 1 - 10 m
T2 = range 6 - 60 s
where
Pause time T1 (the time the air
veyor is idle) is selected using
switches (A) and (B). Then the
time is set using the handwheel
T
= T1.
off
Delay time interval T2 (the time
the air veyor is working) is
selected using switches (C) and
(D). Then the time is set using the handwheel Ton = T2.
