2. GAMBARAN KESELURUHAN PRODUK

This product specification details a stationary 250300 tonperhour (tph) loji penghancuran dan penapisan batu keras. Designed for highvolume aggregate production, this turnkey solution processes quarried limestone, granit, basalt, and similar abrasives to produce precisely graded aggregates for construction, Pangkalan jalan, dan aplikasi konkrit.

Aliran Kerja Operasi:
1. Pengurangan utama: Dumpfed material is crushed by a robust primary jaw crusher to a manageable size.
2. Saringan Pertengahan & Menghancurkan: A conveyor transfers material to a vibrating screen. Oversize is routed to a secondary cone crusher for further reduction.
3. Saiz Akhir & Stok: Correctly sized product from the screen is conveyed to designated stockpiles. Remaining material is sent to a tertiary cone crusher for final shaping before returning to the screen, creating a closedcircuit system for precise control.

Skop Permohonan: Sesuai untuk operasi kuari berskala besar, projek infrastruktur utama yang memerlukan pengeluaran agregat di tapak, and dedicated aggregate suppliers serving regional markets.
Batasan: This plant configuration is designed for stationary installation. Feed material hardness must be within the specified compressive strength limits of the crusher liners. Optimal operation requires consistent feed size distribution as per design parameters.
