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, нэг чанартай, болон дахин боловсруулах өргөдлийг дахин боловсруулах. These systems offer flexibility, бүтээмж, and reduced transportation costs by processing materials on-site.

Key Components of Mobile Secondary Crushing Systems
1. Crusher төрлийн:
- Конус Кручингууд: Хатуу, зүлгүүртэй материалд тохиромжтой (жишээ нь e., боржин чулуу, сагссах), сайн хэлбэртэй дүүргэгч үйлдвэрлэх.
- Нөлөөллийн бутлагчид: Suitable for softer or recycled materials (жишээ нь e., шохойн чулуу, барагшин), offering high reduction ratios.
- Эрүүний бутлаг үндэслэл (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 or electric) for remote operations.
- Compact designs to fit constrained sites.

3. Тэжээлийн систем:
- Receives pre-crushed material from primary crushers (жишээ нь e., 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 (жишээ нь e., 0–5mm, 5-20мм).
- Closed-circuit designs recirculate oversized material for re-crushing.

Сурталчилгаа
- Уян хатан байдал: Rapid setup and relocation between job sites.
- Зардал хэмнэх: Reduces trucking needs by processing on-site.
- Ихэмжиг: Can be paired with mobile primary crushers and screens for full mobile crushing circuits.
- Environmental Benefits: Lowers dust and noise vs. fixed plants in some configurations.

Хэрэгжүүлэх
- Дүүргэгч үйлдвэрлэх (замын Засгийн, бетон дүүргэгч).
- Дахахүү (бетон, Асфальт нураах хаягдал).
- Уул уурхайн үйл ажиллагаа (хүдэр боловсруулах).

Сонголтын талаар
1. Material Hardness/Abrasiveness: Dictates crusher type (cone vs. цохилт).
2. Output Size Requirements: Fine aggregates may need cone crushers; impact crushers excel at mid-range sizes.
3. Үйлдвэрлэлийн хүчин чадал: Match throughput to primary crusher output (жишээ нь e., 150–400 tph for mid-sized operations).
4. Mobility Needs: Track-mounted units suit rough terrain; wheeled options favor road mobility.
