Secondary crushing
Secondary and fine crushing for hard stone aggregate where stable grading and wear resistance are important.
Equipment role
Ruilong cone crushers are selected for hard and abrasive stone where secondary or fine crushing must control product grading. The technical material separates coarse, medium and fine cavity duties and notes that final capacity depends on feed grading, CSS, material density and circuit type.
Selection basis
Selection starts from material condition and plant target, then moves into machine model, chamber configuration, drive power, foundation, conveyor routing and long-term wear-part planning.
Technical parameters
Representative parameter data is organized for preliminary selection. Final model selection should be confirmed against material test data, feed grading, operating hours and plant layout.
| Model | Type | Max feed (mm) | Min CSS (mm) | Motor (kW) | Reference capacities by CSS (t/h) |
|---|---|---|---|---|---|
