Coal may be conveyed directly from the dumper to one of the two outbound silos
Simultaneously, coal may be reclaimed from a pile, and may be directly conveyed from the dumper, to the same outbound silo. Or, each process may be sent to separate silos.
DTA has two outbound silos referred to as SS-2 and SS-3. The coals from both outbound silos may be blended together using 4 vibrating feeders under each silo. Programmable Logic Controllers adjust flow rates from the two outbound silos depending on the blend rates requested by the customer and the actual readings from the electronic belt scales.
The computerized blending process provides highly accurate and consistently homogeneous blending to help maintain a quality product throughout the loading.
