Steel Shot & Grit Systems

VAC-U-MAX has over 50 years experience in pneumatically conveying and vacuum cleaning metal powders. High-density and highly-abrasive powders require a deep understanding of vacuum producers, powder flow, filtration, abrasion, ergonomics and a working knowledge of the steel abrasive finishinbg and peening industry. VAC-U-MAX has developed several configurations of industrial vacuum cleaning systems to address all types of abrasive finishing operations. 

Cast Steel Abrasive Media Material Characteristics:

  • Steel Shot Media (polishing and peening) (left side of photo): Spherical, abrasive, SAE size range (small to large): S70 to S780
  • Steel Grit Media (stripping and aggressive cleaning) (right side of photo): Angular, highly abrasive, SAE size range (small to large): G120 to G10

Cast Steel Hardness: 40 to 65 HRC (Rockwell Hardness “C” scale)

Bulk Density: 230 to 440 lb/ft3

Primary Vacuum Cleaning Applications

  1. Bulk cleaning of below-grade pits, bucket elevator boots, carrier cart tracks (tons of material)
  2. Floor splatter / veneer of material outside blast booth with floor tools 
  3. Cleaning parts of accumulated media with hand tools

Material Handling Options for Collected Abrasive Media

  • 55-gallon drums: primarily for recycling or storage
  • Floor-standing hopper: return media to in-floor screw conveyor or bucket elevator

Elevated hopper: to return media to side or top of blast machine, or vibratory screen

Right: Model 1020-15HP cleans out pits and fills a 55-gallon drums of shot in 16 minutes from 25ft away. Put a cover on the drum and it’s ready to be shipped out for reprocessing.

Below: VAC-U-MAX “Adjustable Bleed” cleaning nozzle buried in the steel shot, requiring very little manipulation. Keep areas around big airless blast motors clear to dissipate motor heat.
