Problem:<br />
Cyclone cones would receive extreme abrasive <strong>and</strong> corrosive wear from a slurry of recycled newspapers,<br />
magazines, contaminates, <strong>and</strong> black liquor. Each cyclone cone replacement cost was $8K.<br />
Solution:<br />
Complete repair area was s<strong>and</strong>blasted to a SSPC-SP5 white metal finish. Flat exp<strong>and</strong>able metal was tack<br />
welded in a raised position 1/4” above the substrate. Tack welding exp<strong>and</strong>able metal improved epoxy’s<br />
mechanical boding properties. Surface areas were then chemically cleaned using Cleaner Blend 300.<br />
FL10 Primer was applied <strong>and</strong> allowed to cure or dry for 15 minutes. FL10 Primer improved chemical<br />
bonding properties of epoxy. Wear Guard Fine Load was applied replacing worn missing metal. Ceramic<br />
<strong>Repair</strong> was applied to repair remaining cavitated areas deeper than 1/4”. Following a 4 hour partial cure<br />
of Ceramic <strong>Repair</strong>, Brushable Ceramic was applied to a thickness of 30 mils in two coats (15 mils each).<br />
Brushable Ceramic provides a long lasting, abrasion <strong>and</strong> chemical resistant protective surface coating.<br />
<strong>Devcon</strong>’s repair cost was $550 each cone, excluding labor.
