The GYRO bin activating feeder produces 360 degrees of pure gyratory motion to discharge granular materials from bins, storage silos, and hoppers at any desired feed rate. At the heart of the feeder is the drive that produces 360 degrees of radial force, creating a uniform circular motion on all parts of the feeder. It is this annular radial vibratory motion that imparts the ultimate force, assuring a constant and reliable material flow. This also minimizes any material stratification in the storage silo or bin and develops a predictable and positive flow of material upon demand. The GYRO bin activating feeder can operate either continuously or as a start and stop operation that might be required for more sophisticated process applications. Also available is an optional variable speed drive that provides a variable material discharge rate with up to a 400 to 1 turndown ratio for batch weighing operations.
