1. PEMBUKAAN PAINPOINT DRIVEN

Adakah anda menguruskan operasi agregat volum tinggi dan menghadapi kesesakan berterusan yang menghakis keuntungan? Untuk pengurus loji dan kontraktor kejuruteraan, loji penghancur batu 250300tph adalah aset pengeluaran yang kritikal, namun cabaran operasi biasa boleh menjejaskan pulangan pelaburannya dengan ketara. These include inconsistent feed material causing crusher stalls and unplanned downtime; excessive wear part consumption driving up costperton metrics; inefficient screening leading to product recirculation and energy waste; complex maintenance procedures that extend service windows; and difficulty meeting stringent, dualgrade product specifications simultaneously. The resulting costs—in lost production, high maintenance labor, and suboptimal yield—are quantifiable. How do you achieve reliable throughput at the 300tonperhour mark while controlling operational expenses? The solution lies in a professionally engineered 250300tph stone crushing plant designed from the ground up for durability, kecekapan, and simplified operation.

2. GAMBARAN KESELURUHAN PRODUK

This product is a stationary, hardrock stone crushing and screening plant engineered for a nominal output of 250 ke 300 Ton metrik sejam (tph). It is designed for primary contractors and quarry owners requiring consistent, pengeluaran agregat volum tinggi untuk pangkalan jalan, asfalt konkrit, dan balast kereta api.

Aliran Kerja Operasi:
1. Penghancuran utama: Bahan suapan besar (up to 750mm) dikurangkan oleh penghancur rahang primer yang teguh.
2. Saringan Pertengahan & Menghancurkan: Output utama dihantar ke skrin bergetar untuk pengelasan. Oversize material is directed to a secondary cone crusher for further reduction.
3. Penghancuran Tertiari/Halus: For specific product cubicity requirements, a tertiary cone crusher or impact crusher processes screened material.
4. Saringan Akhir & Stok: Crushed material undergoes final screening into precise product fractions (mis., 05mm, 510mm, 1020mm) via multideck screens before being conveyed to designated stockpiles.

Skop Permohonan & Batasan:
Skop: Ideal for granite, basalt, Sungai kerikil, batu kapur, dan bahan pelelas lain. Suited for largescale infrastructure projects and permanent quarry sites.
Batasan: Tidak direka untuk aplikasi mudah alih atau mudah alih. Kekerasan bahan suapan mesti sejajar dengan spesifikasi pelapik penghancur yang dipilih. Optimal performance requires consistent feed size distribution as per design parameters.
