Stone Shot Blasting Machine

About Stone Shot Blasting Machine

Loading the Workpiece

• Metal parts (plates, sheets, or components) are placed on a roller conveyor.

• Rollers are usually powered and synchronized to move parts at a controlled speed.

• The conveyor can handle continuous flow of multiple components.

---

2 Conveyor Movement

• The rollers carry the workpiece through the blast chamber.

• The speed of the conveyor is adjusted depending on the degree of cleaning required.

Typical conveyor speed: 0.53 m/min, depending on part size and surface condition.

3 Shot Blasting

• The machine has 4 blast wheels, usually positioned on the top, bottom, and sides of the chamber.

• High-speed steel shots are thrown from the blast wheels onto the moving metal surface.

• All surfaces of the component are cleaned as it passes through the chamber.

Key points:

• Blast wheel speed: ~25003000 RPM

• Shot velocity: 6080 m/s

• Abrasive flow rate: 300500 kg/min (depends on wheel size)

---

4 Abrasive Recovery System

• Steel shots fall into a hopper below the conveyor.

• A screw conveyor moves the used shots to a bucket elevator.

• The separator removes dust and broken particles, returning clean steel shots to the blast wheels.

This ensures continuous operation with minimal wastage.

---

5 Dust Collection

• Dust and fine particles are collected in a dust collector system (bag filter or cartridge).

• Clean air is exhausted outside the machine, keeping the environment safe.

---

6 Unloading

• After passing through the blast chamber, cleaned parts exit the conveyor.

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