H1: Optimize Your Aggregate Production with a Durable Primary Jaw Crusher

Are you facing escalating operational costs due to frequent component wear and unplanned downtime in your primary crushing stage? Does inconsistent feed size from your quarry lead to chokefeeding or cavity loss, reducing your plant's overall throughput? Are you struggling to balance the need for highcapacity fragmentation with manageable energy consumption and maintenance labor hours? Untuk pengurus loji dan kontraktor kejuruteraan, these challenges directly impact profitability. The solution lies in selecting a primary jaw crusher engineered not just to crush, but to optimize your entire downstream process for reliability and costperton efficiency.

Gambaran Keseluruhan Produk: Penghancur Rahang Utama Tugas Berat

This equipment is a stationary, singletoggle primary jaw crusher designed for the first stage of size reduction in quarrying, perlombongan, dan aplikasi kitar semula pembinaan berskala besar. Its operational workflow is built for continuous, pemprosesan volum tinggi:
1. Pengambilan Suapan: Oversized raw material (ROM) is loaded into the vibratory feeder and directed into the deep, kebuk penghancuran tidak tercekik.
2. Penghancuran Mampatan: The robust eccentric shaft drives the moving jaw plate in an elliptical motion, applying immense compressive force against the fixed jaw to fracture the material.
3. -Pelarasan Tetapan Pelepasan: CSS (Tetapan sampingan tertutup) is hydraulically adjustable from the control panel or manually via shim plates, allowing precise control over output product size without stopping the machine.
4. Pelepasan & Pengangkutan: Crushed material exits through the bottom discharge opening onto a main conveyor belt for transport to secondary crushing or screening stages.

Application scope includes processing hard rock types like granite, basalt, dan bijih kasar. Its primary limitation is product shape; jaw crushers produce more elongated particles compared to cone crushers, which may be a consideration for certain highspec aggregate products.
