S26E11 — Vibrating Mining Screens, Whoopie Pies, Wood Utility Poles, Roller Conveyors

Reinforced steel frames, replaceable screening surfaces and powerful vibrators are assembled into machines that separate mined material by size. Soft cake rounds are baked and paired around a sweet filling to make whoopie pies; selected logs are peeled, dried and pressure-treated for use as utility poles; and rows of rollers, bearings and drive systems are mounted in frames to build conveyors.
