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? Para gerentes de planta y contratistas de ingeniería, 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.

Descripción general del producto: Trituradora de mandíbula primaria de servicio pesado

This equipment is a stationary, singletoggle primary jaw crusher designed for the first stage of size reduction in quarrying, minería, y aplicaciones de reciclaje en la construcción a gran escala. Its operational workflow is built for continuous, procesamiento de alto volumen:
1. Consumo de alimento: Materia prima sobredimensionada (memoria de sólo lectura) is loaded into the vibratory feeder and directed into the deep, cámara de trituración sin asfixia.
2. Trituración compresiva: 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. Ajuste de configuración de descarga: El CSS (Configuración del lado cerrado) is hydraulically adjustable from the control panel or manually via shim plates, allowing precise control over output product size without stopping the machine.
4. Descargar & Transporte: Crushed material exits through the bottom discharge opening onto a main conveyor belt for transport to secondary crushing or screening stages.

El alcance de la aplicación incluye el procesamiento de tipos de rocas duras como el granito., basalto, y minerales abrasivos. 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.

Escenarios de aplicación

Estación de trituración primaria de cantera de granito

Desafío： A large granite quarry experienced excessive downtime from tramp metal （drill bits， bucket teeth） causing catastrophic damage to the toggle assembly on their existing jaw crusher， averaging three major stoppages per year.
Solución： Implementation of our PJ1200HD primary jaw crusher with a full hydraulic toggle protection system.
Resultados： In two years of operation， six tramp iron events have been cleared in under two hours total combined downtime with zero component damage， aumentando el tiempo de producción anual disponible en aproximadamente ~300 horas.
