Penghancur Impak Sekunder ialah sejenis mesin penghancur yang digunakan dalam pengeluaran agregat, 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. Prinsip Kerja:
- 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. Jenis Penghancur Impak Sekunder:
- 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.

Perbandingan dengan Penghancur Lain:
- 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.
