Coal Prep<br />
Problem:<br />
Dry coal “fines “ would collect on the trough of the screw conveyer <strong>and</strong> on the screw flyghts. The<br />
constant abrasion will cause cavataion in the trough <strong>and</strong> prevent proper conveying of the coal. Thusly<br />
the trough needed to be rebuilt back to its close tolerance to the flyghts.<br />
Solution:<br />
First the trough was blasted to a SSPC-SP5 near white blast <strong>and</strong> solvent wiped. Then Ceramic <strong>Repair</strong><br />
was applied to the worn gouges <strong>and</strong> holes in the trough to “build up” the large voids. After the material<br />
was cured for at least (4 hours) Brushable Ceramic was applied to a thickness of 30 mils in two coats of<br />
15 mils each. Next the “screw” itself was coated with two coats of Brushable Ceramic (30 mils total) in<br />
two coats.
