About

Loading the Leaf Springs

• Leaf springs are placed on a conveyor belt or chain conveyor.

• The conveyor carries the springs into the blast chamber.

2 Conveyor Movement

• The conveyor moves the springs at a constant speed through the chamber.

• Springs pass under multiple blast wheels positioned at different angles.

Typical conveyor speed: 13 m/min

3 Shot Blasting / Shot Peening

• Blast wheels (24 turbines) rotate at very high speed.

• They throw steel shots / steel grit onto the spring surface.

Typical parameters:

• Wheel speed: 25003000 RPM

• Shot velocity: 6080 m/s

Effects:

• Removes rust and mill scale

• Cleans surface for painting

• Creates compressive stress that increases fatigue life of the spring.

4 Abrasive Recovery System

After hitting the springs, steel shots fall to the bottom hopper.

Recovery process:

1. Screw conveyor collects the shots.

2. Bucket elevator lifts them upward.

3. Air separator removes dust and broken particles.

4. Clean shots return to the blast wheels for reuse.

This creates a continuous recycling system.

5 Dust Collection

• Dust and fine particles go to a dust collector (bag filter).

• Clean air is released outside the machine.

6 Unloading

• After passing through the chamber, the conveyor moves the cleaned springs out.

• Springs are ready for inspection, painting, or assembly.
