Tersiyer darbeli kırıcılar orta ve düşük sertlikte taşların kırılmasında tersiyer (üçüncül) kademede kullanılmaktadır. Rotor ve pandül sistemi ile darbe ve çarpma etkisi ile kırma yapar. Çift yönlü çalışan rotor sayesinde ayar değişikliğine ihtiyaç duymadan iki farklı ürün elde edilebilir ve aşınma avantajı sağlayabilir.
What Are Tertiary Impact Crushers and How Do They Work?
A tertiary impact crusher is an impact crusher designed for fine chippings and sand production; it accepts a smaller feed size and usually has a grinding path or third apron next to the second apron. The rotor runs at a higher peripheral speed to increase the share of fines.
Crushing by impact gives the product a cubical shape, providing the quality required for asphalt and concrete aggregates.
Applications
- 0–5 mm manufactured sand and fine chippings
- Shaping asphalt and concrete aggregates
- Tertiary crushing of limestone and medium-hard material
- An economical alternative to cone crushers for fine crushing
Selection Checklist
- Feed size limited to the secondary crusher product
- Rotor speed and apron gap set for the required fines content
- Material abrasiveness determines wear cost
- Dust control and fines management planned

Frequently Asked Questions
What is the difference between a tertiary impact crusher and a VSI?
A tertiary impact crusher breaks with a horizontal rotor and aprons and is economical in medium-hard material such as limestone; a VSI throws rock against rock with a vertical rotor and suits manufactured sand from hard rock better.
How much sand does a tertiary crusher produce?
It depends on material, rotor speed and apron setting; settings should follow the target grading curve and be confirmed by sieve analysis.
