Shot Blasting Machine Spare Parts Classification

Shot blasting machine spare parts are generally divided into five categories: wear parts, mechanical components, power components, dust removal accessories, and sealing/protection parts.

1. Wear Parts (highest consumption, frequently inquired in foreign trade)

1) Impeller Assembly (core of the blasting turbines)

- Blades: straight blades, curved blades, high-chrome wear-resistant parts, wear fastest

- Impellers (inside the control cage)

- Control Cages (controls shot direction)

- Blast wheels, fastening end cover, retaining ring

The complete set is called the blasting head impeller assembly, the most critical wear part of the shot blasting machine.

2) Liner Plates (wear-resistant plates inside the chamber)

- Top plate, side liner, end liner, door liner

- Material: high-chrome cast iron, manganese steel; round corner liners, strip liners to prevent shots from penetrating the chamber.

3) Rubber Wear Parts

- Tracks: rubber tracks for tracked shot blasting machine

- Rubber curtains, protective rubber plates, shot guard curtains

- Sealing strips, shot recovery rubber plates

2. Shot Circulation System Parts

1) Elevator Section

- Elevator hopper (bucket), elevator belt/chain, belt buckle, drum

2) Separator (air separator)

- Separator screen plate, adjustable baffle, guide plate, used to separate good shots, broken shots, dust

3) Screw Conveyor

- Screw blades, screw shaft, end bearing seat, transports steel shots to the bottom of the elevator

3. Machine Body and Door Mechanism Parts

- Maintenance door, blasting chamber body, hooks (hook-type shot blasting machine)

- Hook assembly, travelling wheels, limit switch

- Trolley assembly (trolley-type shot blasting machine)

4. Dust Removal System Parts (accessories)

- Dust filter cartridge/bag, cage, pulse solenoid valve

- Ash discharge valve, air duct, dust collector sealing ring

Many clients purchase these together with blasting spare parts.

5. Power, Electrical and Sealing Parts

1) Motors: blasting head motor, elevator motor, screw motor, dust fan motor

2) Bearings, bearing seats, couplings, pulleys

3) Seals: oil seal, sealing ring to prevent steel shots from leaking

6. Consumables (sold with parts)

- Steel shots, steel grit, stainless steel shots, white fused alumina abrasives, and other shot consumables

Overseas clients often inquire about:

1) Complete spare parts package for the blasting head (blades + directing sleeve + separator wheel + liner plates)

2) Tracks, elevator hopper, filter cartridge
