1. PEMBUKAAN PAINPOINT DRIVEN

Kos operasi yang meningkat dan masa henti yang tidak menentu menghakis margin pengeluaran agregat anda? Untuk pengurus loji dan pakar perolehan, cabaran teras dalam penghancuran primer selalunya tertumpu pada tiga bidang kritikal:

Masa Henti Tidak Berjadual: Bearing failures or wear part changes can halt your entire processing line. Every hour of stoppage for a primary crusher can cost tens of thousands in lost production and labor.
Jumlah Kos Pemilikan yang Tinggi: Di luar pembelian awal, costs for energy consumption, alat ganti (like mantles, cekung, dan rahang mati), dan penyelenggaraan yang tidak dirancang secara langsung memberi kesan kepada keuntungan anda.
Output Tidak Konsisten & Bentuk produk: Fluctuations in feed material hardness or size can lead to poor reduction ratios and nonspec product, causing bottlenecks in secondary stages and reducing saleable tonnage.

Persoalan utama ialah: how do you select a primary stone crusher machine that delivers not just high capacity, but predictable performance and controlled operational expenditure?

2. GAMBARAN KESELURUHAN PRODUK: Penghancur rahang utama

This product category focuses on heavyduty primary jaw crushers engineered for the initial reduction of large quarried stone (<1500mm) kepada saiz yang boleh diurus untuk pemprosesan hiliran. The operational workflow is defined by a robust compressive crushing action:

1. Pengambilan Suapan: Large raw feed material is loaded into the vibrating grizzly feeder (VGFF VGF) bahagian, yang memintas denda untuk mengoptimumkan pemuatan ruang penghancur.
2. Penghancuran Mampatan: Bahan memasuki plat rahang tetap dan bergerak. Pergerakan elips menggunakan daya mampatan yang besar, breaking stone against stone for efficiency.
3. Pelarasan Tetapan Pelepasan: Saiz produk yang dihancurkan dikawal dengan tepat melalui sistem pelarasan togol hidraulik atau mekanikal, allowing quick changes without downtime.
4. Pelepasan & Menyampaikan: Crushed material exits at the bottom discharge point onto the main product conveyor for transport to the next stage.

Skop Permohonan & Batasan: This equipment is designed as a stationary or mobile primary unit for hard rock (granit, basalt) and abrasive applications in largescale mining and quarrying. It is not suitable for sticky, clayrich materials without prescreening and is typically outperformed by gyratory crushers at capacities exceeding 1,500 tph in fixedplant scenarios.

6. SENARIO APLIKASI

Operasi Kuari Granit – Asia Tenggara

Cabaran: A highproduction quarry faced excessive wear on jaw plates every 90 hari (~130k tons), requiring a full shift shutdown for replacement. Unpredictable bearing temperatures also caused production anxiety.
Penyelesaian: Implementation of our heavyduty primary jaw crusher with bolted wedge wear parts and conditionmonitored spherical roller bearings.
Keputusan: Wear part life extended to an average of 190k tons (+46%), mengurangkan kekerapan pertukaran. Bearing temperature monitoring allowed predictive maintenance scheduling. Overall plant availability increased by an estimated .5%.
