Media blasting entails shooting abrasive media against a surface to: 

  • Smooth out rough surfaces
  • To add texture
  • Remove pollutants (i.e. paint or rust) 
  • Prepare a surface for a fresh coat of paint  

However, media blasting equipment must be well maintained to function correctly. If not maintained properly, any work will have to be put on hold until repairs or replacement parts arrive. 

Media blasting is a process used by several industries including:

  • Shipbuilding
  • Welding
  • Automotive 
  • Construction

Below are the parts that must be maintained frequently to ensure maximum performance and efficiency.

Blast Cabinet

Make it part of your routine to inspect your blast cabinet. You also need to examine your gloves for tears or holes. If they do, throw them out and get a new pair to ensure your hands are protected all the time. You should also look at the gaskets on the door safety switch. These can become worn and won’t close the switch like they should.

Watch for early signs of window frosting. If window frosting is visible, use rubber curtains and replaceable window protectors. These will increase the life of your window, lessening the need for a replacement and stopping cabinet wear and tear.

Blast Nozzle

Blast nozzles will ultimately wear out, creating a wider nozzle opening. When this happens, it changes abrasive consumption and production speed. Therefore, the blast nozzle needs replacing.

The speed at which your nozzle wears down depends on how often it’s used and the abrasive type you use. For example, a nozzle that’s used every day is likely to need replacing faster than one that’s used just for occasional plastic media blasting. Also, harsher materials, like aluminum oxide, will make your nozzle deteriorate quicker than gentler abrasives like glass or plastic beads.

Blast Hose

Wear and tear are inevitable when abrasive is repeatedly run through a hose. If your blast hose is not working, it has become a severe health and safety hazard. It is also very noisy and messy.

Inspect often for soft spots where it bends. Test the hose by squeezing it. If the wall is thinned out, it will press down easily. If you notice any damage, you’ll need to replace the blast hose.

Dust Collector

The dust collector is one of the most vital parts of a blasting machine. This component is designed to store and hold disposable materials and abrasives that have been eliminated from the surface. You must carefully examine the dust bag to make sure the cartridge isn’t clogged and there aren’t any rips. A dust collector gathers and recycles reusable abrasives like aluminum oxide, glass beads, steel shots, and much more. 

Depending on the surface you’re cleaning, you might need to clean the filter every 20 minutes. You also need to empty the dust collector and assess the media reclaim system too. 

Best Practices to Maximize the Effectiveness of Media Blast Equipment

Use the Correct Abrasive Media

The choice of abrasive media has a major impact on the quality of the finished product and blasting job. It’s important to pick the best abrasive for the specific project.

Good Dust Collection and Ventilation Systems  

Good dust collection and ventilation systems are vital for having healthy and hazard-free working conditions. Proper air circulation and dust collection reduce the amount of airborne particles and ensure you’re following environmental guidelines.

Appropriate Personal Protective Equipment 

When it comes to media blasting, safety must be a top priority. Critical safety measures should be in place including proper training, personal protective equipment (PPE), and hazard awareness. To have a safe work environment for your workers, they should have respirators, blast suits, and hearing protection.

Lubricate the moving parts of the equipment according to the manufacturer’s instructions. Accurately lubricating the equipment parts lessens wear and tear, friction, and noise. Make sure there is no dirt on the lubrication points before using the lubricants. Regular lubrication and lubricating of the parts guarantees the media blast equipment operates easily.

Cleaning and Debris Removal 

Frequently cleaning the media blasting equipment eliminates debris, dust, dirt, and abrasive media buildup. Be sure that the separators, dust collectors, filters, and blast cabinets are cleaned according to the manufacturer’s guidelines. Remove clogs and blockages that stop the airflow or abrasive media flow. Every exhaust and vent must be cleaned and working correctly. 

Monitor the Abrasive Media

Monitor the abrasive media used in the blasting job. Assess the media for clues of pollutants like excessive dirt or dust. Get rid of any big particles that might create a blockage or damage the media blast equipment. To retain the effectiveness of the media blast tools, replenish the media frequently.

Checking for Wear and Tear

Over time, the parts of the media blasting equipment are prone to wear and tear. This is why it is vital to frequently examine the equipment to detect signs of deterioration and damage. Pay close attention to the belts, blades, and seals. These parts are known to wear out often because of the blasting operation of abrasive media.

Perform frequent visual inspections of the media blast equipment to find any damage, malfunctions, or signs of wear and tear. You also need to check every part such as blast wheels, hoses, filters, blast nozzles, etc. Look for cracks, tears, or any other type of wear that could deter safety or performance. Taking care of problems now decreases the chances of a breakdown during a blasting job. 

If you see worn-out liners, broken blades, or frayed belts, it is crucial to handle the problem immediately. Replace all worn or damaged parts immediately to stop more injury from happening to the media blast equipment, saving you time and money on the blasting job by keeping the equipment functioning effortlessly.

It’s a smart idea to keep an inventory of spare parts on hand so you can replace damaged or worn components quickly. This includes:
