| External fan listed by the author | Out in PDF3 table, peripheral system supporting instead of built-in/Hardinge self-made proof |
| External fines collector listed by the author | Out in the PDF3 table, the specific type and manufacturer are not included |
| No. | Component | Location |
|---|---|---|
| 5 | 1925 Rotary grader body | Central grader shown connected to cone mill; internal parts not shown |
| 6 | 1925 Rotary system finished product collection cone | The cone-shaped container on the upper right of the original assembly diagram; the finished product is sent to the product bin; external matching |
| 7 | 1925 Rotary system finished product box | Product bin at the lower right of the original assembly diagram; external matching, internal discharge valve is not inferred |
| 1925 Rotary system loop pipe | The pipeline between the original combination diagram grader, upper collector and loop; external accessories |
| Component | Location |
|---|---|
| External fine particle collection device (optional) | Basic recommends fine powder outlet in the process; choose one of cyclone collector or bag filter |
