About hook type shot blasting machine

A Hook Type Shot Blasting Machine is used to clean, de-scale, remove rust, and prepare metal surfaces using high-speed steel shots. It is commonly used for castings, fabricated parts, forgings, and automotive components.

Below is a simple step-by-step working process.

1. Loading the Workpieces

Metal parts are hung on hooks or hangers attached to an overhead conveyor.
Each hook can carry 250 kg to 2000 kg depending on machine capacity.
The hanger moves the parts into the blasting chamber.

2. Door Closing & Safety Lock

Once the parts are inside the chamber, the door closes automatically.
Safety interlocks ensure the machine cannot start if the door is open.

3. Rotation of Hook

The hook rotates slowly (spinner action).
Rotation allows all sides of the component to be exposed to blasting shots.

4. Shot Blasting Process

Inside the chamber, high-speed turbines (blast wheels) throw steel shots.
Shot velocity can reach 6080 m/s.
Shots hit the surface and remove:
- Rust
- Scale
- Sand
- Old paint
- Oxidation

Common blasting media:

Steel shot
Steel grit

5. Shot Collection & Recycling

After hitting the parts:

Shots fall to the hopper at the bottom.
A screw conveyor collects the shots.
The bucket elevator lifts them to a separator.
The separator removes:
- Dust
- Broken shots
Clean shots are reused again.

This makes the process continuous and economical.

6. Dust Removal

A dust collector sucks dust from the blasting chamber.
Filters capture fine particles to keep the working environment clean.

7. Unloading

After the blasting cycle (usually 310 minutes):
- Turbines stop
- Door opens
- Hook moves out
Cleaned parts are removed from the hanger.
