VSI sand maker for fine crushing and aggregate shaping
VSI
A VSI sand maker uses high-speed rotor impact for fine crushing and particle shaping. Select it around the prepared feed size, feed arrangement and required sand grading, then match the surrounding screening, classification or washing stages.

What does a VSI sand maker do in an aggregate plant?
A high-speed VSI rotor accelerates prepared material into an impact zone for fine crushing and particle shaping. The catalogue identifies manufactured sand and aggregate shaping as its duties, with screening after the impact stage.
The reference wet and dry sand-making flowsheets put jaw and cone crushing before the VSI. When an incoming size exceeds the selected VSI limit, review the upstream reduction stage rather than relying on the sand maker to accept that feed.

Which VSI capacity column should a quotation use?
The catalogue gives separate t/h ranges for cascade-plus-centre feed and full-centre feed. Both belong to the same model, but they refer to different feed arrangements. Specify the arrangement when discussing capacity instead of quoting the larger column without its context.
For VSI-8518, the listed maximum feed is below 40 mm for soft material and below 35 mm for hard material. These are separate feed limits; they are not promised finished-sand sizes.
| Model | Cascade + centre (t/h) | Full-centre (t/h) | Soft feed (mm) | Hard feed (mm) |
|---|---|---|---|---|
| VSI-8518 | 200-260 | 100-130 | <40 | <35 |

What changes between a dry and a wet sand-making circuit?
The VSI is present in both reference circuits. The dry route adds powder classification and dust collection; the wet route adds washing, fine-sand recovery and dewatering. The choice concerns the surrounding process, rather than a claim that the VSI alone completes either plant.
- Provide material type, moisture and clay content, and the feed grading reaching the VSI.
- State the required sand grading, fines content, throughput in t/h and proposed feed arrangement.
- Include the screening/recycle connections, plus classifier and dust-extraction arrangements for a dry route or water/slurry handling for a wet route.
