ADL tumblast machine

A Tumblast Shot Blasting Machine is used to clean, descale, deburr, or prepare the surface of metal parts by blasting steel shots at high speed while the parts tumble inside a rotating drum or belt.

Basic Working Principle

The machine works in 4 main steps:

1. Loading the Parts
   • Metal components are loaded into a rubber belt drum or steel tumble chamber.
   • The chamber slowly rotates so parts continuously tumble and expose all surfaces.
2. Shot Blasting
   • High-speed blast wheels throw steel shots (small steel balls/grit) onto the parts.
   • The impact removes:
     • rust
     • scale
     • sand
     • paint
     • burrs
   • Continuous tumbling ensures uniform cleaning.
3. Shot Recovery & Separation
   • Used shots and dust fall into the bottom hopper.
   • A bucket elevator lifts the abrasive to a separator.
   • Good steel shots are reused.
   • Dust and broken particles go to the dust collector.
4. Unloading
   • After the preset blasting time, the drum reverses or tilts.
   • Cleaned parts are discharged automatically or manually.

• Blast wheel / turbine
• Tumble belt or drum

Applications

Tumblast machines are commonly used for:

• Foundry castings
• Forged components
• Automobile parts
• Fasteners
• Small fabricated items
• Heat-treated parts

Advantages

• Uniform cleaning
• High production rate
• Reuse of abrasive
• Less manual labor
• Good for batch processing of small-medium parts

Important Safety Points

• Never open the door during blasting.
• Wear hearing and dust protection during maintenance.
• Check liner wear and blast wheel blades regularly.
• Ensure proper shot size and flow rate.
