Granulator .. Bill of lading .. Packing list drawings, electrical schematics, and manual from the base evacuation area. You can now have the machine lifted from the skid. A forklift is ideal for the purpose, but take care to properly position the forks between the casters and the centrally mounted evacuation pipe from the side of the machine. (See Figure 5) Figure 5: Lifting the Granulator ! CAUTION ! Do not attempt to lift the granulator by means of any shaft or protruding member, ESPECIALLY THE HOPPER 4 Installation 4-1 Lifting Important! Before lifting or moving the granulator, check the relative weight shown on the shipping papers and in Figure 4. To facilitate the lifting operation using forklift trucks, the drop box has been removed from the granulator and is packed with any spare parts. When using a forklift to move the granulator, make sure it is suitable for the weight and dimensions of the granulator. When moving, take care not to damage delicate parts. To lift the machine with a forklift, place the carriage forks under its base (See Figure 5). Where a forklift truck is not available, it is possible to use cables or belts, provided that they are strong enough to support the weight of the granulator, then carry out the lifting procedure. Important! During the movement, the load must remain in a horizontal position, regardless of the type of equipment used. 4-2 Positioning the Granulator Important! Make sure that the base on which the granulator is supported is solid and completely level, in order to rigidly support the granulator without its being subjected to vibration. It is recommended that the floor be reinforced concrete with a very smooth support surface. Place the granulator in an area large enough to allow sufficient space on all sides for the operator to carry out maintenance. Although the granulator controls and electrical components comply with CEE & NEMA codes and regulations, the machine must be placed in an area free from humidity, dampness, and water. The granulator should be installed in an inside covered, weather-proof environment and away from any areas where water collects on the floor. Once the granulator is in position, the front panel must be opened in order to insert the bin as illustrated in Figure 6. Figure 6: Inserting the Bin 4-3 Electrical Connection It is extremely important that the machine is correctly wired into the plant power source by a licensed electrician. See Section 9 for a wiring diagram. All electrical equipment must be properly grounded in accordance with local and national codes to protect personnel from electrical shock. A fusible, lockable disconnect between the plant power source and the machine electrical cabinet is highly recommended. !!Caution!! Before connecting the power, check that the power cable size and capacity corresponds to the horsepower and amp load indicated on the granulator label and that the disconnect switch is in the OFF position. (See Figure 2.) Unless otherwise specified, the granulator has been wired for 480 volts, 60 Hz, 3 ph. The power cable from the plant source can be run directly to the control panel or through the base of the machinery. To run the power cable through the base of the granulator, perform the following steps: 1. Open the back cover, and insert the power cable from underneath the granulator. 2. Pass the power cable through the appropriate hole, and insert it into the control panel through a connector placed at the base. 3. Connect the three phase wires to the appropriate terminals of the main switch, and connect the ground wire to the terminal provided near the main disconnect switch. (See Figure 7.) Figure 7: Electrical Connections 4-4 Start-Up Checks 4-4-1 Checking the Cutting Chamber Before starting the granulator, open the cutting chamber to ensure that during transportation or installation, no foreign objects have Text Box: Phase Wire Terminals fallen in. The use of heavy gloves is recommended to avoid injury when exposed to the knives in the cutting chamber. NOTE: This operation must be carried out by an operator / mechanical maintenance engineer. Check that the cutting chamber is free from foreign objects as follows: 1. Turn off and lockout the machine power to the granulator or remove the fuses from the main control panel. 2. Open the front panel, and remove the bin. Unscrew the screw knob, and carefully lower the screen. (See 3. Figure 8.) 4. Pivot back the feed hopper to gain free access to the cutting chamber. 5. Check that there are no foreign objects in the cutting chamber. 6. Check to be sure the bed knife and rotor knife bolts are at the proper torque and the knife gap is set according to specifications. See Sections 4-4-4 and 6-4. 7. After completing the checks, close the hopper and screen, and fasten them with the corresponding knob; reinsert the bin. Then close both the rear cover and the front panel. 8. Remove the drive belt guard by unscrewing the ten fastening screws. 9. Manually give the ro...
