CASE NO: 063
OBJECT: | Dissolve butadiene crumb rubber into 1,000 gallons of asphalt at 360 degrees F. | PROBLEM: | Crumb rubber tends to agglomerate and “golf ball sized” lumps take 24 hours to fully dissolve. | RESULTS: | Lumps are ground down to minus ¼” in one pass through Dicon – recirculation grinds rubber down to 20 mesh (1/32” or 780 microns). | AB MIXER: | Model 6 x 3 Dicon with heat tracing tape | BENEFIT: EQUIPMENT REPLACED | Complete dissolving occurs in one hour. Batches are now made on demand instead of “day before”. Colloid mill |
