There are over a dozen common types of shot blasting machines on the market; the mere seven categories—drum, crawler, hook, overhead conveyor, roller conveyor, turntable, and trolley—are enough to leave one feeling dizzy.
I. What exactly is the difference between them? And which types of workpieces are they each suitable for?
Table 1: Model + Suitable Workpieces + Weight + Features
| model | Suitable workpiece | Weight | Features |
| Drum-type | Small Castings and Forgings, Forgings, Fasteners, Springs | ≤50kg | Bulk |
| Track type | Small to Medium-sized Castings, Die Castings, Heat-treated Parts | ≤100kg | Small to Medium Batch |
| Hanger type | Large-scale Castings, Structural Components, Thin-walled Parts | ≤2 ton | Single Pieces / Small Batches |
| Catenary type | Automotive Parts, Castings, Gas Cylinders, Wheel Hubs | ≤500kg | Large-Scale Assembly Line |
| Roller conveyor type | Steel Plates, Structural Shapes, Steel Pipes, Structural Components width | ≤4m | Large-scale Continuous |
| Rotary table type | Medium-sized irregular parts, gears, valves | ≤500kg | Small to Medium Batch Production |
| Trolley-type | Ultra-large Castings | ≤500kg | Single Pieces / Small Batches |
Table 2: Model + Advantage + Limitations + Typical Industries
| model | Advantage | Limitations | Typical Industries |
| Drum-type | Low cost, large loading capacity | Workpieces collide with each other | Foundry Industry, Standard Parts |
| Track type | Rubber tracks protect the workpiece | Not suitable for deep-cavity parts | Auto parts |
| Hanger type | Collision-free; supports timed projection | Low efficiency | Construction Machinery, Molds |
| Catenary type | Fully Automatic, Continuous Operation, High Efficiency | High investment, difficult to switch production | Automobile Manufacturing |
| Roller conveyor type | Suitable for long workpieces | Not suitable for irregularly shaped parts | Steel and Shipbuilding |
| Rotary table type | Fixed positioning, uniform projection | Limited production capacity | Precision Components |
| Trolley-type | High Load-Bearing Capacity, Rotatable | Large footprint, high investment | Heavy Machinery, Wind Power |
II. Three Steps for Model Selection
Step 1: Inspect the Workpiece
1. What are the dimensions of the workpiece? How much does it weigh? Is its shape complex or regular?
2. Is it a thin-walled component, a precision part, or a heavy, rugged piece?
3. Are there any deep cavities or blind spots that require cleaning?
4. Is there a risk of the workpieces colliding with one another? — If so, drum-type or crawler-type systems would not be suitable; instead, priority should be given to hook-type, turntable, or trolley-type systems.
Step 2: Consider Production Volume
1. Single-piece or Small-batch Production (e.g., molds, large structural components) → Hook-type, Trolley-type, or Turntable-type systems
2. High-volume Assembly Line Production (e.g., automotive parts, standard components) → Overhead Conveyor-type, Roller Conveyor-type, Drum-type, or Track-type systems
Step 3: Check the Requirements
