CONAIR 1. Introduction This manual is for CONAIR MARTIN's 79 series granulators. The abbreviations mean: -B = Band conveyor -U = Suction blower -L = Low level -V = Ejector (Air Veyor). 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 MARTIN granulators are built for granulation of

CONAIR 3. Functional description 3.1 Overview 79 granulators are designed for grinding different types of plastic waste. 79 A B C D E A 79 D B C E 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 necess

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

CONAIR 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 "

CONAIR 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. 5.2 Opening and c

CONAIR 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). Check the granulator motor’s rotation direction as follows: • Set the main circuit-breaker on the control box to position (1) = “On”. • Check that the emergency stop switch is not activated. It can be reset by turning the knob in the direction of the arrow (anti-clockwise). • Check that the break scre

CONAIR 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 wh

CONAIR 6.3 Cleaning 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, 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 A hard to avoid only one of the link screws taking the whole load. Note: S

CONAIR 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 drop- shaped. Always take great care when handling the knives since they are very sharp and can cause personal injury. Use protective gloves! 7.1.1 Changing th

CONAIR Assembling the rotating knives 1. Clean the cutter's knife location and place a rotating knife in the knife location. 2. Fasten the screws (A) together with the washers (H) and tighten gently. 3. Adjust the knife using the setting screws (B) to give the correct amount of play, 0.15-0.30 mm between the fixed and rotating knives. Check using the feeler gauge included in the tool kit. 4. When the correct amount of play has been obtained, tighten the screws (A) with a torque of 200 Nm. 5. Tig

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

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 sharpen

CONAIR 7.3 Inspecting and adjusting the belts The V-belts must be inspected after 30 hours’ operation. • Loosen and remove the outer plate on the belt guard. • Load one of the V-belts between the rotor pulley and the motor pulley with 25 N in the middle of and at a F = 25 N right angle to the belt. Measure the l = 6 mm deflection and adjust the distance between the pulleys as necessary until the tension is correct. The V-belt should stretch 6 mm. Adjusting: • Tension the belt by screwing on the

CONAIR 7.5 Rotor pulley, assembling/disassembling 7.5.1 Rotor pulley Disassembling 1. Loosen all screws a few turns. 2. Unscrew two of the screws. 3. Lubricate both screws and screw them into the disassembling holes (A). 4. Tighten both disassembling screws alternately until the flange bushing comes loose from the hub and the unit sits freely on the axle. 5. Lift the whole unit from the axle. Assembling 1. Clean and degrease the contact surfaces carefully. 2. Place the "flange bushing" in the hu
