The VIRA Engineering Gyro Screen (also known as Vibro Sifter or Shifter) is a circular gyratory screen separator that provides precise grading and separation for powders, granules, and liquids. It utilizes a special vibrator motor with adjustable eccentric weights, creating multi-plane vibrations (horizontal, vertical, and circular) that enable accurate screening with minimal screen clogging.

Multiple screen decks can be mounted one above the other, allowing separation into several fractions in a single operation. Its robust design and high screening accuracy make it ideal for industries requiring consistent particle size distribution.
