Product Description
J.H. Day industrial mixers — including double-arm sigma-blade and dough-style mixers — served chemical, food, cosmetic, adhesive, and pharmaceutical batch operations from the 1940s through the 1980s. According to publicly filed asbestos litigation records, the agitator shaft stuffing boxes allegedly used woven asbestos-fabric packing, and the tilt-bowl cover and jacket flanges allegedly sealed with compressed asbestos sheet gaskets.
Repacking the shaft seals, scraping cured product from blade shafts, and hand-cutting replacement flange gaskets during clean-in-place downtime allegedly released respirable asbestos fibers.
