Media Recovery Systems for Blast Rooms

Media Recovery Systems

Belt Conveyor, Screw Conveyor, Sweep-In Hopper, Flat-Trak®, and M-Section® Media Recovery Systems

Media is expensive, as is the time spent to shovel it up for disposal when operators could be blasting instead. So the more you can reuse media, the more profitable your operation. Problem is that the wrong recovery system for your media or generic, one-size-fits-all recovery systems will quickly wear out, produce inefficient media working mixes, or don’t work to begin with. You need a recovery system designed to optimize recovery of your specific blast media into the most effective media working mix for your blasting applications.

Clemco manufactures five media recovery systems, all with flexible designs and configurations, all fabricated and assembled in-house at Clemco. Mechanical or pneumatic, full floor or partial floor, Clemco has the media recovery system to maximize the performance of your entire operation and to provide a solution for your specific process.

Four Mechanical Media Recovery Systems – For Steel Grit, Steel Shot, and Other Heavy and/or Coarse Media

Belt Conveyer – Efficient, Cost Effective, Low Maintenance

  • Passive Transfer = Lower Maintenance, Lower Expenses – Belt conveyor systems (think of belt-driven transportation systems in the mining industry) are a passive transfer system, meaning that media is funneled through hoppers and then rests on a belt for transfer versus being aggressively pushed or pulled. Passive transfer results in less wear, maintenance, and downtime.
  • Fast Recovery – This low-maintenance, passive system is also fast compared to other mechanical recovery systems.
  • Ideal for Angular Media ­– If aggressive, angular media has worn out your other recovery systems, a belt conveyor system is the ideal solution for maximizing uptime.
  • Flexible Installation Options – Belt conveyor systems can be configured for partial sweep-in or full-floor recovery to fit any application and blast room requirements.
  • Only Offered by Clemco – Clemco is the only abrasive-blasting equipment manufacturer that offers belt conveyer recovery systems.

Screw Conveyor Recovery System

Screw Conveyor – Time-Tested and Economical

  • Reliable and Simple – Screw conveyors have been a popular choice for abrasive recovery for decades because they provide a time-proven and simple media recovery method, making them easy to use and familiar for maintenance.
  • Ideal for Non-angular Media – Excellent recovery systems for steel shot since rounded steel shot will not bite into the screw.
  • Flexible Installation Options – Belt conveyor systems can be configured for partial sweep-in or full-floor recovery to fit any application and blast room requirements.

Sweep-In Hopper – When a Full-Floor Recovery System Is More Than You Need

  • Smaller Blast Rooms and Lower-Volume Blasting – Smaller blast rooms and lower-volume blasting operations likely recover less media than larger abrasive blasting operations, so a capital investment such as a full-floor recovery system may not be needed.
  • Economical and Efficient – Sweep-in hoppers are an entry-level recovery option that can be configured as a 2 ft x 2 ft surface-mounted hopper or a 3 ft x 3 ft in-ground hopper, yet still provide the benefits of abrasive recycling and cleaning.
  • Quicker Installation – The 2 ft x 2 ft surface-mounted hopper does not require foundation work, saving installation time and expense.

Flat-Trak Recovery Systems

Flat-Trak – When Surface-Mounted Installation Is Required

  • Pit or Surface Mounted – Many blast recovery systems require a pit to be excavated. However, Flat-Trak recovery floors can be pit or surface mounted. Surface-mount capability can be critical when foundation renovations are not possible due to issues such as lease agreements, high water tables, or staying within a budget.
  • Full-Floor – All Flat-Trak systems are full-floor. Vanes powered by a pneumatic cylinder are embedded within a Flat-Trak’s low-profile floor. The vanes efficiently transport media by pushing it through a series of channels.

Pneumatic M-Section Recovery Systems – For Glass Bead, Starch, Plastic, ALOX, and other Low to Medium-Density Media

  • Pneumatic Recovery Benefits: Less Wear, More Uptime, Less Expense – Lightweight media requires less force to transport than heavier media because . . . it weighs less. M-Section Systems transport lightweight media via streams of high-velocity air. Because they have no moving parts in the recovery floor itself or in the media stream, M-Sections have fewer components to maintain, that may fail, or that may damage your media.
  • Cyclone Reclaimer Benefit: More Efficient Recovery – Reusable, lightweight media is more difficult to separate from dust and fines than is heavier media. However, the M-Section’s cyclone reclaimer allows for precise fine-tuning of its recovery settings so that it separates reusable media from dust and fines, even if the difference in weights is minor.
  • Pit or Surface Mounted – M-Sections can be configured to fit any size room and cover as much of the floor area as desired. They can be mounted in a pit or on top of an existing foundation.

Abrasive blasting (formerly known as sandblasting) also is called grit blasting, bead blasting, media blasting, soda blasting, dry blasting, sponge blasting, shot blasting, and shot peening. However, sand should never be used when abrasive blasting because breathing abrasive containing crystalline (free) silica can lead to serious or fatal lung disease.
