How To Choose A Sampling System For A Coal Operation

Jun 03, 2018 Sampling coal and coke is a rigorous application. Both products can be very abrasive and corrosive and the movement of this material through metal chutes and sampling devices inevitably takes its toll on the equipment. Cutting costs through less robust metals and materials will always reveal themselves as the equipment operating hours mount.
