Untitled Document Rotating Drum Magnet
Rotating drum magnets are designed for continuous self-cleaning of ferrous materials from product flow streams. As product enters the housing inlet, an adjustable feed gate meters the flow of product to the drum face. The drum has a stationary internal magnet with an outer drum that rotates. When product passes over the powerful magnetic field, ferrous materials are attracted to the drum surface where they are safely held onto until the ferrous material passes through the magnetic field, where it is discharged to the rear of the drum housing. Cleaned filtered product is discharged to the front of the drum housing.

Automatic Gates
Industrial-grade AutoAire automatic gates can supply dust-collection air where and when it is needed, thereby “stretching” available air or eliminating wasted capacity. Solenoids (available in most voltages) control the air cylinders, opening and closing the gates as the machine or operation is turned on. The gates operate without individual controllers but can be tied to controllers, programmable logic controllers, or variable frequency drives to provide extensive system control. They are available in 3-in. and larger sizes.

Gravimetric Inventory Management System
The Gravimetric inventory management system weighs repelletized material prior to its being reprocessed or stored as inventory and can verify delivered resins before entering them into inventory. The system can be configured to operate in a continuous mode for loading silos or other surge bins for storage or as a batching system for loading Gaylord boxes for storage. It can provide totals for a given production shift, a complete production run, or an overall running total of material. Pellet material is conveyed either from a pelletizer, storage, or delivery unit into a surge hopper via a pressure or vacuum system. The surge hopper has a high-level view window for quick visual inspection of the material level within the bin, as well as a cleanout door and a high-level proximity sensor. The sensor shuts down the conveying system and prevents the system from overfilling. The material is then discharged from the surge hopper through a slide-gate into a weighed hopper. The material is discharged through a second metering gate into a Gaylord box or is conveyed to either a storage silo or storage bin via a vacuum or pressure system.
