Mobile Secondary Crushing: Overview and Key Considerations

Mobile secondary crushing refers to the use of portable crushers to further process materials after primary crushing, typically in mining, steengroef, en herwinningstoepassings. These systems offer flexibility, doeltreffendheid, and reduced transportation costs by processing materials on-site.

Key Components of Mobile Secondary Crushing Systems
1. Breker tipes:
- Kegelbrekers: Ideal for hard and abrasive materials (bv., graniet, basalt), goed gevormde aggregate te produseer.
- Impak Brekers: Suitable for softer or recycled materials (bv., kalksteen, asfalt), offering high reduction ratios.
- Kaakbrekers (for secondary): Less common but used for specific applications requiring coarse output.

2. Mobility Features:
- Track-mounted or wheeled chassis for easy relocation.
- Self-contained power (diesel of elektries) for remote operations.
- Compact designs to fit constrained sites.

3. Voerstelsel:
- Receives pre-crushed material from primary crushers (bv., jaw or gyratory crushers).
- May include vibrating feeders or conveyor belts for consistent material flow.

4. Screening Integration:
- Some units feature built-in screens to classify output into desired sizes (bv., 0–5mm, 5– 20 mm).
- Closed-circuit designs recirculate oversized material for re-crushing.

Voordele
- Buigsaamheid: Rapid setup and relocation between job sites.
- Kostebesparings: Reduces trucking needs by processing on-site.
- Skaalbaarheid: Can be paired with mobile primary crushers and screens for full mobile crushing circuits.
- Omgewingsvoordele: Lowers dust and noise vs. fixed plants in some configurations.

Aansoeke
- Gesamentlike produksie (padbasis, beton aggregate).
- Herwinning (beton, asfalt sloping afval).
- Mining operations (ore processing).

Seleksie-oorwegings
1. Material Hardness/Abrasiveness: Dictates crusher type (keël vs. impak).
2. Output Size Requirements: Fine aggregates may need cone crushers; impact crushers excel at mid-range sizes.
3. Produksie kapasiteit: Match throughput to primary crusher output (bv., 150–400 tph for mid-sized operations).
4. Mobility Needs: Track-mounted units suit rough terrain; wheeled options favor road mobility.
