While engineering a new system to load gypsum stucco for ceiling tile manufactured at a sister plant, the United States Gypsum Company plant in Sperry, Iowa, faced the challenge of screening gypsum materials at 30 tph in a low-headroom area. The raw material contained on-size and oversize gypsum particles, paper fuzz, blasting cord pieces and tramp metals from upstream mining and milling operations... In this low headroom space, U. S. Gypsum faced the challenge of laying out a separation system and a conveying system to move the screened gypsum to a bulk tanker truck.

French

Domaine(s)
  • Minéralurgie (Métallurgie)
DEF

Opération au cours de laquelle les particules (morceaux) du ferro-alliage retenues par un tamis après le tamisage sont orientées à la main, de manière à établir la possibilité de leur passage par le tamis avec une classification justifiée des particules retenues (morceaux) en tant que refus de tamisage.
