Secondary crushing with an impact crusher
Rotor blow bars accelerate material into the impact zone. Rotor and impact-plate settings govern secondary reduction and particle shaping.
Define the incoming material and the product required after this stage. The crusher has to be selected together with its feeding arrangement and the screening or conveying equipment that follows it.
Applications to discuss
- Limestone processing
- Secondary aggregate crushing
- Particle shaping
Models and reference specifications
| Model | Specification (mm) | Feeding Opening Size (mm) | Max. Feeding Length (mm) | Capacity (t/h) | Power (kW) | Weight (t) | Overall Dimension (mm) |
|---|---|---|---|---|---|---|---|
| PF-1007 | 1000×700 | 400×730 | 300 | 35–60 | 55 | 7 | 2400×1560×2680 |
| PF-1010 | 1000×1050 | 400×1080 | 350 | 60–90 | 75 | 11 | 2532×1985×2196 |
| PF-1210 | 1250×1050 | 400×1080 | 350 | 80–130 | 110 | 14 | 2638×2037×2713 |
| PF-1214 | 1250×1400 | 400×1420 | 350 | 90–180 | 132 | 19 | 2580×2400×2810 |
| PF-1315 | 1320×1500 | 860×1520 | 350 | 160–250 | 200 | 24 | 2840×2748×2556 |

The catalogue column "Specification (mm)" is retained as written. Comparable PF manufacturer tables call this rotor size, but the TONZO dimension definition remains to be confirmed from a drawing. Capacity entries are reference values and must be checked against the actual material and duty.
Inputs for PF crusher selection
| Selection input | What to provide |
|---|---|
| Material | Limestone or other proposed feed; provide rock characteristics, moisture and clay content. |
| Incoming feed | Maximum feed length and the normal particle-size distribution. |
| Required product | Target throughput, product-size fractions and particle-shape requirements. |
| Line interfaces | Existing primary crusher or feeder, discharge arrangement and downstream screening. |
Define the supply scope
State whether the requirement is a single secondary crusher, replacement of an existing machine, or a crushing and screening line. Include the feeding, conveying and dust-control connections that belong in the supply scope.
Send the material and operating requirements for this equipment.
