Low-profile vibratory screen separators: Increasing capacity for tough materials
Separating oversize particles is critical to controlling
your product quality, whether you need to separate
oversize from incoming dry bulk materials before they flow into your process or from processed materials before they’re packaged. A low-profile vibratory
screen separator with its minimal height and coaxial material flow is a popular choice for this safety-screening step. After describing single- and dual-motor low-profile separator's, how to measure and adjust their vibratory motion, and deblinding methods for both units, this article explains how the dual-motor separator can increase screening capacity for hard-to-screen materials.
A low-profile vibratory screen separator consists of a round, enclosed screen with a feed inlet at the center top and an undersize discharge at the center bottom. An oversize discharge spout is at one side of the screen, and one or two vibratory motors are located at the screen periphery. This configuration makes the low-profile separator different from a standard round vibratory screen separator in two major ways: One, the standard eparator’s undersize discharge is at one side of the unit,
rather than on the same central axis (coaxial) with the material inlet as in the low-profile unit. Two, the standard separator’s motor (or motors) is under the unit rather than on the screen periphery as in the low-profile unit. These differences reduce the low-profile separator’s height, giving
the unit its headroom-saving profile — a key advantage
for the typical safety-screening application.
