1. APERTURA IMPULSADA POR EL PUNTO DE DOLOR

¿Está gestionando un rendimiento impredecible?, excessive liner wear costs, and unplanned downtime in your primary crushing circuit? Inconsistent feed size from the mine, coupled with abrasive gold ore containing hard quartz or sulfide components, directly impacts mill feed and overall recovery rates. These operational challenges translate into measurable costs: every hour of crusher downtime can stall hundreds of tons of processing, and premature wear part replacement carries a significant recurring expense.

Are you evaluating crushing equipment that can handle variable feed without choking, reduce the frequency of maintenance shutdowns, and deliver a consistently coarse product for optimal SAG mill or heap leach performance? The selection of your primary gold ore crushing equipment is a critical capital decision that determines circuit stability for years.

2. DESCRIPCIÓN GENERAL DEL PRODUCTO

This product line encompasses heavyduty primary jaw crushers engineered specifically for the rigorous demands of gold mining operations. The operational workflow is designed for reliability: (1) RunofMine (memoria de sólo lectura) ore is fed via grizzly to remove fines, (2) the crusher’s robust chamber reduces large feed (hasta 1200 mm) through compressive force, (3) a regulated discharge setting ensures a consistent product size, typically between 150250mm, for downstream conveyance. This equipment is applicable for hard rock gold ores (lode deposits) and is the foundational stage in comminution circuits feeding milling or heap leach pads. Its primary limitation is in processing alluvial or placer deposits where minimal crushing is required.

3. CARACTERÍSTICAS PRINCIPALES

HeavyDuty Manganese Steel Jaws | Base técnica: Highgrade, alloyed manganese steel workhardens under impact. | Beneficio operativo: Liners develop a hard, wearresistant surface throughout their life, extending service intervals in abrasive conditions. | Impacto del retorno de la inversión: Reduces liner inventory costs and labor for changes by up to 30% compared to standard alloys.
Palanca hidráulica & Sistema de ajuste | Base técnica: Replaces traditional mechanical toggle plates with a dualacting hydraulic cylinder. | Beneficio operativo: Enables remote clearing of tramp metal and chamber blockages in minutes and allows quick CSS adjustment for product control. | Impacto del retorno de la inversión: Eliminates hours of dangerous manual clearing, minimizing safety risk and increasing crusher availability.
Modular Frame Design | Base técnica: Fabricated from hightensile steel plates with precision machined interfaces for key components. | Beneficio operativo: Simplifies transport to remote sites and allows for strategic component replacement during planned maintenance. | Impacto del retorno de la inversión: Reduces foundation requirements and installation time by approximately 25%, lowering total installed cost.
Aggressive Toothed Profile & Cámara de trituración profunda | Base técnica: Optimized nip angle and tooth geometry increase grip on slabby material. | Beneficio operativo: Significantly reduces slippage and choking with sticky or clayrich gold ores, maintaining rated throughput. | Impacto del retorno de la inversión: Prevents costly flow stoppages and ensures steady feed to downstream processes.
Integrated Motor & Drive Guarding | Base técnica: Enclosed vbelt drives and motor mounts designed as part of the crusher structure. | Beneficio operativo: Protects critical drive components from dust ingress and physical damage in harsh plant environments. | Impacto del retorno de la inversión: Extends drive component life and reduces unplanned electrical motor failures.

6. ESCENARIOS DE APLICACIÓN

Hard Rock Underground Mine Transition to Open Pit

Desafío: An expanding operation needed a primary crusher capable of handling both the competent ore from underground development and the more variable, weathered material from the new open pit without constant adjustment or blockages.
Solución: Implementation of a largecapacity jaw crusher with an aggressive stroke and hydraulic toggle system as the primary gold ore crushing equipment at the ROM pad.
Resultados: Achieved a blended throughput at design capacity of 950 TPH; reduced blockagerelated downtime by over 80% compared to the previous system.

HighAltitude Heap Leach Operation

Desafío: A site at high elevation required reliable equipment with reduced maintenance complexity due to limited local technical support and harsh weather conditions.
Solución: Installation of two modular jaw crushers with extendedlife liners and fully enclosed drives.
Resultados: Crushers met targeted 200mm product size for optimal leaching; liner changeout intervals were extended to match seasonal planned shutdowns, eliminating unscheduled maintenance.
