A Primary Impact Crusher is a heavy-duty machine used in the first stage of crushing (первичное дробление) to break large rocks, руды, или другие твердые материалы на более мелкие, более управляемые части. 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 (до 1-2 метры) 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 (известняк, гипс, уголь) 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, добыча полезных ископаемых, и приложения для переработки.

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.

Общие приложения:
- Карьерные работы & Агрегаты (известняк, гравий)
- Cement Industry (crushing raw materials)
- Переработка (конкретный, отходы от сноса асфальта)
- Горное дело (primary reduction of ore)

- Климанн М.Р. 110/130 EVO

Considerations When Choosing a Primary Impact Crusher:
✔ Feed size & твердость материала
✔ Desired output size & production capacity
✔ Maintenance requirements (wear parts like blow bars)
✔ Energy efficiency & эксплуатационные расходы
