1. Introduction
This manual is for CONAIR MARTIN'S 79 granulators, where A = Screw feed (Auger)
This manual must 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 MARTIN 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 MARTIN
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 MARTIN in order to avoid personal injury and damage to machinery and to ensure that the documentation remains correct.
If you have any questions, please contact your local dealer or our head-office.

3. Functional description
3.1 Overview
The 79 granulator is designed for grinding different types of plastic waste. The granulator is controlled from an electrical cabinet with a start/stop function
and an emergency stop button.
B
C
A
D
E
The material is fed into the hopper (A) and is pushed towards 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). On the standard model, the operator must take out the granule bin to empty it. As an option, the granulator can be fitted with a suction blower which sucks the granulate out of the granule bin.
The granule bin, screen and screenbox are designed so that they can be easily released when cleaning.

CONAIR MARTIN
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 control panel. 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 when the screenbox is pulled out a safety switch is actuated which cuts off the power so that the rotor and screw stop before the screenbox can be opened.
Similarly, for the hopper, a safety switch is actuated by a loop being pulled out of the switch and breaking the electric circuit when the locking clamp is pressed down and the inlet funnel or protective cover is released.

4. Safety regulations
4.1 Overview
CONAIR MARTIN granulators are built for granulation of injection moulded, blow moulded or extruded plastic waste, which must not exceed the granulator's size and performance as described in chapter 2.
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:
WARNING! High Voltage! The electrical installation work must only be carried out by authorised personnel!
Always switch off the power supply using the main circuit-breaker (on top of the electrical cabinet) before opening the granulator. WARNING! High voltage remains on the incoming phase's connection block and up to the main circuit-breaker!
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 screenbox and the hopper are locked.
= WARNING! High Voltage!
This sign is placed on the electrical cabinet's door and any connection boxes.
= WARNING! Risk of being cut or caught in the machinery!
This sign is placed as necessary next to dangerous parts, for example the hopper and screenbox.
As long as the instructions in this manual are followed carefully, there should be no other dangers.

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 are 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.
Check the knife clearance and tightening torque on the attachment bolts for the knives.
5.1.1 T wo hours after first start
CONAIR MARTIN
Check the knife clearance again and tightening torque of the attachment screws for knives; check the attachment screws for both the fixed and rotating knives.
5.2 Opening and closing the hopper and screenbox
Screenbox:
The screenbox is held in place by a spring-loaded hoisting mechanism, which is manoeuvred using the bar (4). Release the screenbox by moving the bar until it is horisontal.
1. Pull out the granule bin (3). A safety switch on the back of the granulator is then activated, which breaks the current to prevent the machine from being started with the screenbox open.
2. Loosen the socket-head nut at the top of the clamping ring (1). Turn the granulator, by using the motor as a lever, to the position shown in the figure opposite. Simultaneously put your weight against the motor so that the granulator does not turn freely and damage the blower motor.

4. Lower the link screws (2a, 2b) against the screen and lift out the screen
holder.
5. Lower the link screws against the inside (as for 2b) of the cutter housing and
lift out the screen for cleaning or changing the knives.
Hopper:
1. Release the protective cover or inlet funnel by pushing down the locking
clamp (2) and pulling the funnel axially over the locking clamp. The safety switch's locking clamp is released, which cuts off the current to the screw motor and prevents the granulator from being operated with the hopper open.
5.3 Electrical connection
The granulator should be connected up by an authorised electrician.
Connect the granulator to the mains supply. See Electrical scheme, chapter␣ 9, connecting (Q1).
All connected electric motors have been set up with the intended rotation direction by setting up the internal electrical connection for clockwise rotating field.
Using a phase-sequence indicator, check that the incoming phases are
connected to the granulator so that the intended, clockwise rotating field is maintained.

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
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 2 safety switches, 1 for the locking clamp by the
screw feed, and 1 for the screenbox:
Screenbox: Check the safety switch by loosening the granule bin as described in chapter 5.2. It should not be possible to start the granulator until the hoisting mechanism's bar has been set in a vertical position after the granule bin has been put into place.
Hopper: Open the hopper as described in chapter 5.2, but close and lock the granule bin. Check the safety switch to the hopper by starting the granulator. It should not be possible to start the granulator until the hopper is closed and the locking clamp is back in position.

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 SF 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:
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 figure

7.3 Disassembling/assembling the screw
7.3.1 Disassembling
Release the cover on the bearing
housing.
Straighten the locking lug on the
folding washer and loosen the KM­nut on the clamping ring.
Tap the KM-nut so that the
clamping ring releases from the shaft.
Lift away the end cover and place an extractor (1) there.
Screw in the screw (2), which should reach at least 15 mm in the thread in the
granulator screw.
Alternately tighten the lifting screws (3) so that the whole time the extractor is
parallel with the end of the cutter housing. To reduce the pulling force, pressure oil can be used as described below.
Disassembling the screw using pressure oil
In the screw shaft close to the worm gear unit there is a plugged hole for connecting to a pressure-oil pump, for example a separate pump to a hydraulic jack. In this way, oil is pumped into the shrinkage fit via an oil duct, which means that considerably less force is required to pull the screw from the gear.
7.3.2 Assembling
Before assembling the screw, the shaft and hole should be dry and clean. The shaft is sprayed with Molykote anti-slipping lacqueur.
Place two 0.2 mm feeler gauges together between
the seal-ring and the cutter housing so that the distance between these is 0.4 mm.
Heat the screw shaft to 225 0C and place it on the
gear shaft.
Cool the screw shaft with cutting fluid until it has
cooled down to under 100 0C.
Release the feeler gauge and fit the end cover.
The ball bearing is locked in the middle of the
bearing housing in axially in such a way that the bearing can take up the axial change as a consequence of the generation of heat in the granulator.
The bearing is locked on the clamping ring by a KM-nut, which is locked with
the folding washer.

CONAIR MARTIN
7.4 Lubrication
The bearing is delivered filled with grease and, under normal running conditions, needs to be lubricated after 10,000 hours or every other year with grease of type Castrol Spheerol APS-2 or similar quality.
When delivered, the gears are filled with an oil which is especially intended for worm gear units. The oil is synthetic and must not be mixed with mineral oils. Normally it should not need to be replaced. With this oil the gears can be used in an ambient temperature between -30 0C to +30 0C.
