A Primary Impact Crusher is a heavy-duty machine used in the first stage of crushing (nghiền sơ cấp) to break large rocks, quặng, hoặc các vật liệu cứng khác thành nhỏ hơn, phần dễ quản lý hơn. Unlike jaw crushers, which use compression force, impact crushers utilize high-speed impact to fracture materials.

Key Features of Primary Impact Crushers:
1. High Reduction Ratio – Capable of reducing large feed sizes (lên đến 1-2 mét) into smaller fragments in a single pass.
2. Horizontal Shaft Design – Uses rotating hammers or blow bars to strike and throw material against breaker plates.
3. Versatility – Can handle soft to medium-hard rocks (đá vôi, thạch cao, than đá) and some abrasive materials.
4. Adjustable Output Size – The gap between the rotor and impact aprons can be adjusted to control product size.
5. High Throughput Capacity – Suitable for high-production quarrying, khai thác mỏ, và ứng dụng tái chế.

Advantages Over Other Primary Crushers:
- Better cubical-shaped end product compared to jaw crushers.
- Higher reduction ratio in a single stage.
- Effective for softer materials where compression crushers may generate excessive fines.

Ứng dụng phổ biến:
- khai thác đá & Tập hợp (đá vôi, sỏi)
- Cement Industry (crushing raw materials)
- Tái chế (bê tông, chất thải phá hủy nhựa đường)
- Khai thác mỏ (primary reduction of ore)

Mô hình phổ biến & Nhà sản xuất:
- NP Series
- CI Series
- Hazemag AP-PH Series
- Kleemann MR 110/130 EVO

Considerations When Choosing a Primary Impact Crusher:
✔ Feed size & độ cứng vật liệu
✔ Desired output size & production capacity
✔ Maintenance requirements (wear parts like blow bars)
✔ Energy efficiency & chi phí vận hành
