Overview:
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.
