5.Turbo only-Paddles improperly adjusted for the production requirement.Replacement paddles <br /> that are field installed are sometimes adjusted improperly.Occasionally, a row of blades can <br /> unintentionally be installed backwards. Refer to recommended paddle settings in this manual or <br /> call Scott Equipment for further discussion. <br /> Problem:Product is improperly processed. <br /> Possible Solutions: <br /> 1. Infeed drive is malfunctioning;resulting in product delivery in surges or none at all. <br /> 2. Hopper above infeed conveyor is bridging material. <br /> 3.Check paddles to ensure all paddles are at the correct pitch,and are all present. <br /> 4.Contact Scott Equipment for further discussion of paddle setting.There are different settings <br /> of the paddles that can accomplish increased or decreased retention. <br /> 5. Paddles or screens are worn. <br /> Problem:Machine must be cleaned due to screens plugging. <br /> Possible Solutions: <br /> 1.The paddles are excessively worn and are too far from screen surface <br /> 2. If the paddles have too much clearance with the outside wall,product will build up on the wall <br /> of the machine.The closer the clearance,the better the self-cleaning performance <br /> Problem:Main shaft heating up. <br /> Possible Solutions: <br /> 1. Material is bound around seal area. Open seal cover and inspect. Remove any wrapping or <br /> buildup. <br /> 2. Bearings are improperly lubricated. Make sure all the bearings and bearing races are free <br /> moving within housing.Check that the shaft is not turning within the inside bearing race,and <br /> that all set screws are properly tightened. Ensure that lubrication is according to the bearing <br /> manufacturer's recommendation. <br /> Feeder Operation <br /> 1.The hopper should contain material at all times so feeding is consistent to the separator. <br /> 2.The conveyor is designed to have material tumble back into the hopper and produce a <br /> consistent feed rate into the separator. <br /> 3.The conveyor is either a chain drag conveyor or a screw conveyor. Both have reducers and <br /> motors. Proper lubrication is necessary. <br /> 4.The chain drag must have proper chain tension.Only enough tension is required to keep <br /> excessive slack out of the chain. <br /> 191 Page <br />
