Manual dump to rigid bin weigh batching system

October 1, 2007

The Manual Dumping Station features a high-velocity vacuum fan that draws airborne dust from the operator''s atmosphere onto two cartridge filters. Automatic reverse-pulse filter cleaning allows continuous, efficient operation; timer-activated solenoid valves release short blasts of compressed plant air inside cartridge filters causing dust build-up on the outer filter surfaces to fall into the hopper. Filters are accessed easily by removing the interior baffle, and replaced rapidly using quick-disconnect fittings. The Manual Dumping Station’s surge hopper discharges into a Low-Profile, De-Lumping Device with dual rotors and three-point heads that break up agglomerates that have formed in the bag. On-size material is discharged into a Gravimetric Feeder that is connected via PLC to a scale on the plant floor, allowing accurate batch weights to be loaded into rigid totes placed on the scale.
