Smico Vibratory Screeners and Feeders says it designed and tested a new high-capacity screen. The standard large-capacity unit is 5 feet wide by 12 feet long with 360 square feet of screening area. The largest unit is 5 feet by 18 feet with 540 square feet of screening area. The screen imparts a vertical, bouncing motion and comes in a choice of three different brute force drive types — single-shaft elliptical drive, dual-shaft linear motion drive, and twin canned-motor style drive. These drives are said to be up to 30 percent more efficient than gyroscopic motion drive types.
