Introduction to Portable Sand Blasting Machine in India 

A portable sand blasting machine in India, also known as a portable abrasive blasting machine or portable sand blaster, is a compact equipment used to clean, etch, and prepare surfaces by propelling abrasive material under pressure. This method is widely used in surface preparation, corrosion removal, rust cleaning, paint removal, and industrial maintenance. The portability allows for flexible use onsite or in small workshops.

Key technical terms:

• Abrasive media: sand, aluminum oxide, steel grit, glass beads, etc.
• Air compressor: An air compressor provides pressurized air.
• Sand blasting nozzle/gun: The sand blasting nozzle directs the abrasive stream.
• Sand blasting hose: Sand blasting hose carries abrasive to the nozzle.
• Pressure pot: Sand blasting chamber containing abrasive under pressure.

How Portable Sand Blasting Machines Work

The operation is based on three main principles:

• Air supply: Compressed air (typically 90-120 psi or 6-8 bar) enters the machine via an air compressor.
• Abrasive feed: The abrasive media, like sand, aluminum oxide, garnet, or glass beads, are gravity-fed or siphoned into the air stream.
• Protrusion through nozzle: The mixture exits via a nozzle at high velocity (speeds up to 200-300 m/s), striking the surface to remove contaminants or roughen it.

Components Portable Sand Blasting Machine 

Pressure Pot & Hopper

Pressure pot and sand blasting hopper is a sealed vessel where abrasive media is stored. Pressure feed pots maintain 50-90 psi. Made from steel or aluminum.

Blast Gun & Sand Blasting Nozzle (orifice)

• Throat: nozzle entrance section.
• Orifice: inside diameter; 3/16″-¾″ sizes; affects media flow and coverage area.
• Nozzle Material: tungsten carbide or ceramic; resists wear.
• Venturi nozzle: creates suction for siphon-feed.

Sand Blast Hose

Rubber-lined sand blasting hose rated for 100-200 psi. Sizes vary (⅜″-1″ internal diameter). Connects the pot to the sand blasting nozzle.

Air Compressor & Air Treatment

Compressor capacity (SCFM - standard cubic feet per minute) must match blaster needs. Common is 10-20 SCFM and 100-150 psi.
Air filtration includes:

• Air/oil separator
• Moisture trap
• Regulator (controls pressure)
• Filters (0.01 µm)

• Sand: low cost, silica dust is hazardous.
• Garnet: moderate hardness, dust-free.
• Aluminum oxide: Aluminum oxide is a hard abrasive media and reusable.
• Steel grit: Steel grit is extremely hard, heavy.
• Glass beads: gentle, finishes smoothly.
• Walnut shell: It is a non-metallic abrasive media for delicate surfaces.
• Plastic beads: Plastic abrasive media used on soft materials.

Portable Sand Blasting Machine Safety Equipment

• Sand Blasting Helmet: Sand blasting helmet used in sand blasting machine operation, heavy-duty and air-fed for full head and respiratory protection.
• Respirator or Supplied Air: Protects lungs from harmful dust and fine particles.
• Blast Gloves: Abrasion-resistant gauntlets to protect hands and forearms.
• Coveralls: Full-body suit to shield skin and clothing from abrasive media.
• Ear Protection: Essential for reducing exposure to high noise levels (100-120 dB).

Operation of Sand Blasting Machine in India 

• Setup: Place pot on a stable surface; attach regulator, filter, and hose to air compressor outlet at ~90-120 psi.
• Add abrasive: Choose the correct grade and pour abrasive media into the pot; seal the lid.
• Connect gun and nozzle: Choose nozzle orifice, attach to gun, then to hose.
• Adjust air pressure: Set regulator to recommended psi (e.g., 60-80 psi).
• Safety check: Wear PPE such as a sand blasting helmet, gloves, and coveralls. Inspect hoses, fittings for leaks.
• Test blast: Short bursts to check pressure and pattern; adjust nozzle distance (2-6″).
• Blasting: Sweep evenly; keep nozzle steady; maintain distance.
• Shutdown: Close air valve, depressurize pot, vent pressure, clean pot, and inspect nozzle for wear.

Advantages of Portable Blasting Machines

• Mobility: Easy to transport for on-site jobs.
• Versatility: Works on metal, concrete, wood, and plastic.
• Cost-effective: Lower price than stationary sand blasting cabinets.
• Efficiency: Fast cleaning or rust removal.
• Surface prep: Ideal for paint and coating adhesion.
• Adjustable pressure: Tuned via nozzle, compressor, and regulator.

Benefits of Portable Sand Blasting Machine

• Fast, effective cleaning and surface prep.
• Versatile across materials and applications.
• Economic operation is maintained.
• Portable, ready for on-site usage.
