2. GAMBARAN KESELURUHAN PRODUK

The Industrial 250300tph Stone Crushing Plant is a stationary or semimobile aggregate production system engineered for processing hard rock (granit, basalt) and abrasive materials at high throughput. It is designed as a multistage crushing and screening solution for largescale quarrying, mining preprocessing, dan projek infrastruktur utama yang memerlukan konsisten, specification aggregates.

Aliran Kerja Operasi:
1. Pengurangan utama: Dump feed is received into a vibrating grizzly feeder which bypasses subsize material and directs larger rock to a robust primary jaw crusher for initial size reduction.
2. Sekunder & Penghancuran tertiari: The primary crushed material is conveyed to secondary cone crushers for further reduction. A tertiary cone crusher or vertical shaft impactor (Semua orang) stage may be integrated for precise shaping and fine aggregate production.
3. Saringan Bahan & Menyusun: Crushed material is routed through multideck vibrating screens to separate it into precise size fractions (mis., 05mm, 510mm, 1020mm).
4. Recirculation & Stok: Oversize material from screens is recirculated back to the appropriate crusher stage in a closed circuit. Onspec aggregates are conveyed to designated stockpiles.

Skop Permohonan & Batasan:
Skop: Sesuai untuk operasi kuari besar, highway construction material supply, railway ballast production, and concrete/ asphalt plant feed.
Batasan: Not suitable for fully mobile applications requiring frequent relocation. Feed size must be controlled per primary crusher inlet specifications. Highly claycontaminated or wet feed may require preprocessing to prevent clogging.
