Choosing the right shot blasting machine is crucial to the production efficiency of the factory. In the actual selection process, many factors need to be considered comprehensively. The following is a practical selection method.
Workpiece characteristics evaluation
Material: Different materials such as cast iron, cast steel, aluminum alloy, etc. have different requirements for shot blasting process
Size range: Measure the size and weight of the largest workpiece
Surface state: Existing oxide thickness, degree of rust, etc.
Determination of process requirements
Cleaning level requirements (such as Sa2.5 level)
Whether surface strengthening treatment is required
Subsequent process docking requirements
Common shot blasting machine type comparison
Type | Applicable workpiece | Typical case |
Hook type shot blasting machine | Single large piece | Large casting cleaning |
Crawler type shot blasting machine | Small parts | Hardware rust removal |
Through type shot blasting machine | Plate profile Continuous production | Steel plate pretreatment |
Specialized equipment is preferred for large-scale production of a single product
Multiple products and small batches are suitable for flexible configuration
Special-shaped workpieces require customized solutions
Shot blasting system
The number of shot blasters is configured according to production capacity requirements
The motor power needs to match the workpiece processing requirements
Adjustable shot blasting angle is more conducive to complex workpiece cleaning
Shot selection
It is recommended to use different shot blasting equipment with new equipment
Establish a shot consumption account to optimize the cost of use
Regularly test the shot breakage rate
Dust removal system
The air volume configuration should leave a margin
Filter material selection should take into account local climate characteristics
Set up maintenance channels for easy maintenance
Actual selection process
Demand survey
Collect typical workpiece samples
Statistical production rhythm requirements
Clear site restrictions
