As a key equipment for surface treatment, the material selection of shot blasting machine directly affects the use effect and economic benefits. The following is a material selection scheme that has been verified in practice for your reference.
High manganese steel (ZGMn13)
Characteristics: Excellent impact resistance
Advantages: A hardened layer will be formed on the surface under continuous impact
Applicable to: Cleaning of large castings
Note: A running-in period is required for initial use
Wear-resistant alloy steel (NM400/NM500)
Characteristics: Hardness reaches HRC50 or above
Advantages: Outstanding wear resistance
Applicable to: Continuous working environment
Note: Welding process requirements are high
Rubber lining
Characteristics: Good buffering performance
Advantages: Effectively reduce noise
Applicable to: Thin-walled parts processing
Note: Regular inspection and replacement are required
Shot blasting machine blades
Preferred: High chromium cast iron (Cr26/Cr28)
Characteristics: Hardness HRC58-65
Lifespan: Up to 5-10 times that of ordinary steel
Maintenance: 500-1 000-hour replacement cycle
Shot wheel assembly
Recommendation: Same material as blades
Purpose: Ensure wear consistency
Advantage: Extend overall service life
Conventional selection
Cast steel shot: Best value for money
Stainless steel shot: First choice for rust prevention
Wire cut shot: Efficient cleaning
Special needs
Ceramic shot: Precision parts processing
Glass shot: High requirements for surface finish
Economic configuration
Chamber body: NM400 steel plate
Blade: Cr26
Shot: Cast steel shot
Durable configuration
Chamber body: ZGMn13 composite structure
Blade: Cr28
Shot: Stainless steel shot
Corrosion-resistant configuration
Chamber body: 304 stainless steel
Shot: Ceramic shot
Regularly check the status of wearing parts
Maintain appropriate maintenance cycle
Adjust parameters according to working conditions
Establish spare parts replacement records
