Hanger Type 4 Wheel Shot Blasting Machine

Loading the Components

• Metal parts are hung on hooks or hangers attached to a rotating monorail or trolley system.

• The hanger carries parts inside the blasting chamber.

• Parts can include castings, forgings, weldments, or fabricated structures.

---

2 Closing the Blast Chamber

• Once the hanger moves inside, the blast chamber door closes automatically.

• This prevents steel shots and dust from escaping.

---

3 Shot Blasting by 4 Wheels

Inside the chamber there are four high-speed blast wheels.

• Each wheel throws steel shots or abrasive media at very high velocity (6080 m/s).

• The wheels are positioned at different angles to ensure full surface coverage.

Process:

1. Abrasive shots hit the metal surface.

2. Rust, scale, sand, and paint are removed.

3. Surface becomes clean and slightly rough, ideal for coating or painting.

4 Rotation of Hanger

• The hanger rotates slowly during blasting.

• This allows all sides of the component to be exposed to the abrasive shots.

---

5 Shot Collection & Recycling

After hitting the component:

• Steel shots fall to the bottom hopper.

• A screw conveyor or bucket elevator collects them.

• Shots pass through a separator:

  • Good shots reused

  • Dust and broken shots removed

This makes the system continuous and economical.

6 Dust Collection

A dust collector system:

• Sucks dust from the chamber.

• Filters it using cartridge or bag filters.

• Keeps the environment clean and safe.

---

7 Unloading

• After the set blasting time (usually 310 minutes):

  • Wheels stop.

  • Door opens.

  • Hanger moves out.

• The cleaned parts are removed.
