ABSTRACT 1. INTRODUCTION Conveyor Dynamics
CDI measured coal degradation on a 9 km overland by placing sizeselected coal into individual bags, sealed to contain moisture and unsealed to show difference in coal strength due to moisture loss during transport. Bags were placed on the overland feed point and removed after transport to the head end, as shown in Figure 8.
