Three-Pile Blending

You are here:

One grade of coal is reclaimed from one reclaimer directly to one of the two outbound silos (SS-3). After that silo has been filled…

Two reclaimers can simultaneously reclaim coal from two more piles to be conveyed to the other outbound silo (SS2) at a proportional rate.

DTA has two outbound silos referred to as SS-2 and SS-3. The coals from both outbound silos are 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.

This computerized blending provides highly accurate and consistently homogeneous blending to help assure quality throughout the loading.
