CONAIR MARTIN 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 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.
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.
CONAIR MARTIN 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.
CONAIR MARTIN 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.
CONAIR MARTIN 3. Loosen the two collar nuts (1) which retain the screen holder. 2a 1 2b 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.
CONAIR MARTIN 6. Operation and daily maintenance 6.1 Starting and stopping The start and stop functions are controlled by a push-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 restarted which can overload the motor and trigger the overload protector. 6.
CONAIR MARTIN 6.3 Cleaning NOTE: Set the main circuit-breaker to position "0" when cleaning the granulator. Empty the granulator of all material before re-starting. Always take great care when handling the knives since they are very sharp and can cause personal injury. 1. Open the hopper and screenbox as described in chapter 5.2. 2. Clean the hopper, screen and granule bin. 3. Clean the cutter-housing and inside the stand. 4.
CONAIR MARTIN 7. Servicing All servicing work should be carried out by a qualified service engineer and in the order described, to prevent personal injury or damage to machinery. 7.1 Changing the knives When changing the knives, also check for any wear to the screen. For safety reasons, this should be replaced when the holes in the screen become dropshaped. Always take great care when handling the knives since they are very sharp and can cause personal injury. Use protective gloves! 7.1.
CONAIR MARTIN Assembling the rotating knives 1. Clean the cutter's knife location and place a rotating knife there. 2. Screw in the fastening screws (C) with washers and gently tighten the screws. NOTE:␣ Check that the washers do not bear against the fixed knives. 3. Adjust the knife using the setting screws (B) until the correct amount of play, 0.20 - 0.30 mm, is obtained between the fixed and rotating knife. Using the feeler gauge inlcuded in the tool kit, check the amount of play. 4.
CONAIR MARTIN 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.
CONAIR MARTIN 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 secondary relief angle, 400 , is sharpened. A 05-15-96 • Loosen the screws and remove the stirrup (A), fasten the knife again.
CONAIR MARTIN 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.
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.
