1. APERTURA IMPULSADA POR EL PUNTO DE DOLOR

Are your gold ore processing operations constrained by persistent bottlenecks and escalating costs? The primary crushing stage sets the tone for your entire recovery circuit, and suboptimal equipment here creates a cascade of downstream inefficiencies. Los desafíos comunes incluyen:

Tiempo de inactividad excesivo: Frequent liner changes and unplanned maintenance in abrasive gold ores halt your milling circuit, costando miles por hora en producción perdida.
Capacidad de bajo rendimiento: Inadequate feed opening or crushing force creates a bottleneck, preventing your SAG/ball mills from operating at designed capacity and limiting overall plant yield.
Poor Product Gradation: Inconsistent discharge sizing, with excessive fines or oversized material, reduces grinding circuit efficiency and can negatively impact downstream recovery processes like leaching or flotation.
Altos costos operativos: Premature wear component failure, coupled with high energy consumption per ton crushed, directly erodes profit margins.
Problemas de manipulación de materiales: Equipment not engineered for variable ore hardness (from soft oxidized ore to hard quartz vein material) leads to packing, puente, and unreliable feed.

Is your current gold ore crushing equipment a reliable asset or a recurring liability? The right primary crusher is not an expense; it’s a strategic investment in plant stability and metallurgical performance.

2. DESCRIPCIÓN GENERAL DEL PRODUCTO: HEAVYDUTY GOLD ORE CRUSHING EQUIPMENT

Our engineered solution for primary equipos de trituracion de mineral de oro is built for maximum availability and throughput in demanding mineral processing environments. This machinery is designed to accept runofmine (memoria de sólo lectura) gold ore directly from the mine haulage system.

Flujo de trabajo operativo:
1. ROM ore is dumped into a rugged vibrating grizzly feeder, which scalps out fine material and directs oversize to the crusher.
2. Ore enters the crusher’s large feed opening and is subjected to highpressure compressive force between a fixed surface and a moving mantle/liner.
3. Crushed product discharges onto a main conveyor at a consistent, predetermined size set by the crusher’s closedside setting (CSS), ready for secondary crushing or direct feed to a grinding circuit.

Ámbito de aplicación: Ideal for primary crushing of goldbearing ores including hard rock quartz veins, sulphide ores, and mixed oxidesulphide materials. Suitable for both stationary plant installations and modular/trackmounted setups for satellite deposits.

Limitaciones: Not designed as a standalone solution for final product sizing; requires integration with secondary crushing or grinding circuits for liberation. Maximum feed size is constrained by model selection.
