TM 5-3895-374-102. Feeder CalibrationItemProcedure1If feed rate from any one bin is to exceed the 50 tons per hour selected during aggregate scalecalibration the following changes must be made.2Open the bin gate on all feeders that will feed greater than 50 tons per hour.3The gates should be raised (opened) one inch per 10 tph. (i.e.-a 7 inch opening will result in anexpected maximum feed rate from the bin of approximately 70 tph).4Do not select a greater feed rate than the expected maximum.-Keyboard press ESCAPE-utilities (8), calibration (6), feeder rates (8).-edit (00)-enter the expected maximum feed rate for the bin being calibrated-ESCAPE-By aggregate sample (4)5Select feeder (1), enter feeder number to be calibrated.6Do these 3 in sequence starting with feeder one.7Enter feeder 1.8ESCAPE.9Set test parameters (4).10Enter the anticipated flow rate at the normal plant production rate for the bin selected. (i.e. mixdesign requires 40% course aggregates and asphalt production rate of 150 tph the selectedfeeder for the course materiel will feed 60 tph).11Enter the moisture content for the materiel to be metered from this bin.12Enter the test time interval. (It is recommended that this interval should not be less than sixminutes and need not exceed 15 minutes.)13Press START for the following motors:Feed ConveyorScalping ScreenGathering Conveyorpage 2-90
