3.1 Recovery Separation System: The media recovery separation systems shall start with an air cyclone, highly balanced separator, which receives all expended media and debris conveyed from the pneumatic media recovery floor. The cyclone action centrifugally separates the media from the conveying air stream and collects oversized debris in a removable filter screen and deposits reusable media into the initial recovery hopper. The dust and broken media are pulled through the center vortex tube along with air to the media system dust collector.

3.2 Cyclone Construction: The media recovery cyclones shall be fabricated from 12 ga. hot rolled steel. Manual adjustments to the cyclone system shall include static pressure, to adjust airflow through the system for fine adjustments in the recovery system with major adjustments made by an externally adjustable pipe inside the vortex tube.

All storage hoppers shall be completely sealed except for top mounted man access hatches with all necessary ladders, platforms and safety railings required for access. All hoppers shall have sight level glasses visible from the ground level such that the operator can visually see the level of plastic media in the hoppers and internal air-assisted flow aids to prevent plugging and bridging. Full, re-start, and low level probes shall be provided in all hoppers to stop and start media transfers, prevent overfill conditions, and indicate low media conditions. The full level probes shall be installed in a location that is not affected by any media conveying systems and at a level a full point of 95% of the interior volume of the hopper. The restart level probes shall be installed at a lower level in the hopper to provide a restart delay of the media conveying system. Low level probes shall be installed above the media outlets to indicate an empty media state. All full, restart delay on, and low level probes shall have indicator lights on the control panel. All hoppers shall have slide gate valves at their outlets to allow maintenance of associated equipment without requiring the hopper to be emptied of media. Media storage and recovery equipment shall be rated for Class II Division 2 for hazardous location. All ducting and equipment shall be correctly grounded per NFPA requirements.

4.1 Media Recovery and Cleaning Systems: Recovery and cleaning shall be designed with all required air locks such that the media in the hoppers is stored at ambient pressure.

The slide gate valve shall be used to stop media flow when the magnetic separator is removed for cleaning or for other maintenance operations. The magnets shall be mounted in a self-cleaning removable drawer to allow rapid cleaning of all magnets. An ionized air injection system shall be provided at the outlet of the magnetic separator to help eliminate the build-up of static electric charge in the media. The ionized air knife, below the rotary feed valve, shall only come on when the rotary feed valve is in operation. The air knife shall cover the full width of the duct to ensure coverage of media.

4.3 Vibratory Separators: A vibratory separator shall be provided at the outlet of the magnets and ionizer to separate large waste and fines from the recovered media.

4.4 Heavy Particle Separators: The output of good media from the vibratory separator shall be to a heavy particle separator (HPS) provided to separate all dense particles from the recovered media. The HPS shall be a fluidized bed design. All heavy contaminates, exhaust, and dust generated by the HPS shall be sent to the system dust collector and all reusable media to the clean media storage hopper. The HPS shall be equipped with a manually operated bypass to allow deletion of the HPS from the process flow, while retaining all other separation equipment and returning the reclaimed media to the blast system media storage hopper. When the HPS is in the bypass mode, it shall automatically clear of media and turn off to reduce unnecessary wear on the system components. An HPS bypass indicator light shall be provided on the control panel to indicate when the system is in bypass mode.

4.5 Storage Hoppers: Each blast systems’ clean media hopper shall be sized to maintain 120 cubic feet per minute system flow rates.

The probe shall control the media cleaning and conveying equipment prior to the hopper. Upon a full condition, the controller shall stop the initial recovery hopper outlet rotary feed valve but allow the transfer systems, rotary air locks, vibratory separator, and HPS (only when in the process flow) to run for a timed interval until all systems are clear of media. After this interval, all systems shall shut down until the restart level probe is uncovered. The full level probe shall be installed at a location that is not affected by the media conveying system and at a level a full point of 95% of the interior volume of the hopper. The restart condition shall be an adjustable time delay from a restart level probe being uncovered to provide a delay in the restart of the media cleaning and conveying systems. The time interval shall be adjustable for time intervals of a minimum of five (5) minutes to a maximum of fifteen (15) minutes. All media cleaning and conveying equipment shall restart after this delay period.
