1. PEMBUKAAN PAINPOINT DRIVEN

Adakah anda menghadapi kesesakan yang berterusan dalam litar penghancuran utama anda yang mengehadkan keseluruhan pemprosesan loji? Cabaran memproses keras, abrasive gold ore are welldocumented: excessive liner wear leading to frequent maintenance shutdowns, unplanned downtime from tramp steel damage, and inconsistent feed size reduction that stresses downstream milling operations. Each hour of unscheduled stoppage at the primary stage can cost tens of thousands in lost production. Tambahan pula, inefficient crushing directly increases energy consumption per ton in subsequent grinding stages—your plant’s largest operating cost.

Are you evaluating equipment that can deliver higher availability, mengurangkan waktu buruh penyelenggaraan, and provide a consistently optimal product size for your SAG or ball mill feed? The solution requires a primary crusher engineered not just for capacity, but for the specific abrasion and impact demands of goldbearing rock.

2. GAMBARAN KESELURUHAN PRODUK

Barisan produk ini memberi tumpuan kepada HeavyDuty Primary Jaw Crushers engineered explicitly for gold ore processing. Direka sebagai peringkat kritikal pertama dalam kominusi, mesin ini menerima runofmine (ROM) suapan terus dari trak pengangkutan lombong.

Aliran Kerja Operasi:
1. Pengambilan Suapan: bijih emas ROM (sehingga 1.5m saiz ketulan) is dumped directly into the vibrating grizzly feeder (VGFF VGF), which scalps out fine material.
2. Pengurangan utama: Oversize material is conveyed into the crusher’s fixed and moving jaw dies, where highpressure mechanical force fractures the rock.
3. Size Discharge: Pelepasan produk yang dihancurkan ke penghantar utama pada tetapan sisi tertutup yang telah ditetapkan (CSS), typically between 150mm to 200mm for SAG mill feed.

Skop Permohonan & Batasan:
Skop: Sesuai untuk simpanan emas hard rock (mis., urat kuarza, bijih sulfida), largescale openpit or underground operations requiring hightonnage primary reduction.
Batasan: Tidak sesuai untuk basah, sticky ores without modified feed systems; memerlukan asas konkrit yang stabil dan perancangan pemasangan yang penting. For direct heap leach applications requiring finer product, secondary crushing is necessary.
