Crusher impak sekunder
A Secondary Impact Crusher is a type of crushing machine used in aggregate production, perlombongan, and recycling to reduce the size of materials after primary crushing. It is designed to handle softer to medium-hard rocks (mis., batu kapur, asfalt, konkrit) and produce a more cubical product compared to primary crushers.

Ciri -ciri utama:
1. Fungsi:
- Processes pre-crushed material (from jaw or gyratory crushers) into finer, more uniform sizes.
- Ideal for shaping aggregates and improving particle quality.
2. Working Principle:
- Utilizes impact force from rotating hammers/blow bars striking the material against breaker plates or aprons.
- Material is crushed by high-speed impact and shear forces.
3. Types of Secondary Impact Crushers:
- Impak aci mendatar (HSI): Common for softer materials; Nisbah pengurangan yang tinggi.
- Impak aci menegak (Semua orang): Better for cubical shaping (mis., Pengeluaran pasir).
4. Kelebihan:
- Menghasilkan berbentuk dengan baik, uniform end products.
- Higher reduction ratio than cone crushers for certain materials.
- Lower operating costs in some applications compared to compression crushers.
5. Aplikasi:
- Pengeluaran agregat (Pangkalan jalan, konkrit, asfalt).
- Kitar semula (konkrit, sisa perobohan).
- Perlombongan (soft to medium-hard ores).
6. Batasan:
- Not ideal for very hard or abrasive materials (mis., granit).
- Higher wear on blow bars/hammers than compression crushers.
Comparison with Other Crushers:
- Penghancur utama (Rahang/gyratory): Handles large raw feed; keluaran kasar.
- Crusher impak sekunder: Refines material; bet

shape/size control.
- Penghancur kon: Better for hard/abrasive rocks but less cubical output.
