![]() ![]() While room dividers have been in use for thousands of years - in 8th-century Japan folding screens were used to create privacy among open floor plans - they’ve fallen out of necessity in recent centuries as interiors have become increasingly walled off.ĭespite this, designers remain devoted to them, employing them in less expected scenarios. Whether used to wall off sleeping quarters in a loft or hung as art, considering clever room divider ideas can help energize a room. Wills, B.A., 1997, Mineral Processing Technology, 6th Edition, Butterworth-Heinemann, Boston, Massachusetts, 486 pp.While seating and tables tend to get the lion’s share of the attention (and budget) when redecorating a space, there’s no denying the transformative powers of a folding screen or room divider.

Recently, Eriez has shown through modeling and pilot-scale testing that the innovative approach to feed presentation offered in the CrossFlow teeter-bed separator provides improved metallurgy when compared to traditional hindered-bed classifiers or single-stage coal spirals. Hindered-bed separators are recognized as low-cost, high-capacity devices for both classification and density separation however, since their inception there have been few significant advances in the fundamental technology.
