ISO Certified Gyratory Crusher

1. APERTURA IMPULSADA POR EL PUNTO DE DOLOR

Every hour of unscheduled downtime in your primary crushing circuit costs between $15,000 y $50,000 en producción perdida. If your current gyratory crusher is experiencing frequent spider bushing failures, inconsistent mantle wear patterns, or throughput bottlenecks below 1,500 MTPH, you are bleeding margin on every ton. Plant managers report that outdated crusher designs require 1218 hours for a mantle change, pushing maintenance crews into overtime and increasing safety risks. Engineering contractors face the challenge of integrating a crusher that must handle feed sizes up to 1,500mm while maintaining a P80 product of 150200mm without constant adjustment. Is your current equipment delivering the mechanical availability of 95%+ that your quarterly targets demand?

2. DESCRIPCIÓN GENERAL DEL PRODUCTO

The ISO Certified Gyratory Crusher is a primary compression crusher engineered for highcapacity reduction of hard rock and ore. It operates on a fixed spindle design with a rotating eccentric assembly, delivering continuous crushing action.

Flujo de trabajo operativo:

• Entrada de feed: material de runofmine (up to 1,500mm) enters the crushing chamber via a feed cone and spider assembly.
• Rotación excéntrica: A 500700 RPM eccentric sleeve rotates the main shaft, creating a gyrating motion against the concave liners.
• Trituración por compresión: Material is crushed between the mantle and concave in a continuous downward spiral, reducing particle size.
• Descargar: Producto triturado (típicamente 80% passing 150200mm) exits through the bottom of the chamber into a discharge hopper.
• Ajuste hidráulico: Hydroset system adjusts the crusher setting (CSS) remotely to compensate for wear or change product size.

Ámbito de aplicación: Trituración primaria en la minería de roca dura (cobre, oro, mineral de hierro), canteras de agregados, and largescale cement operations. Limitaciones: Not suitable for sticky or clayrich materials exceeding 8% contenido de humedad; requires a minimum feed size of 300mm to maintain chokefed conditions.

A: Sí. The base frame footprint is compatible with most 6089" gyratory crusher foundations. We provide a foundation adapter kit (included in pricing) that accommodates bolt patterns from AllisChalmers, Raíces, and Sandvik models. A site survey is recommended to verify dimensions.

q: What is the expected lead time from order to delivery?
A: El plazo de entrega estándar es 1620 weeks for GY42 and GY60 models, y 2430 weeks for GY72 and GY89 models. Rush orders (1214 semanas) are available with a 15% expedite fee, subject to foundry capacity.

q: How does the Hydroset system handle power outages?
A: The system includes a nitrogencharged accumulator that maintains hydraulic pressure for up to 8 horas. For extended outages, a manual hand pump allows CSS adjustment. An optional backup battery pack (12V) proporciona 4 hours of electronic control operation.

q: What is the recommended maintenance schedule for the eccentric assembly?
A: Inspect eccentric bearings every 500 horas de funcionamiento. Replace grease and check oil filters every 1,000 horas. Major eccentric overhaul is recommended at 12,00015,000 horas, depending on operating conditions. Field data shows average eccentric life of 18,000 hours in hard rock applications.

q: Does the crusher meet environmental noise regulations?
A: Sí. Sound levels at 1 meter distance are 8590 dB(A) bajo carga, compliant with OSHA and EU directives. An optional acoustic enclosure reduces noise to 75 dB(A) and is recommended for urban or noisesensitive sites.

q: ¿Qué formación ofrecen a los operadores de plantas??
A: We offer a 3day onsite training program covering startup procedures, Ajuste CSS, liner wear monitoring, and emergency shutdown protocols. Training includes a digital manual with video tutorials. Remote refresher sessions are available quarterly.

q: Can this crusher handle highclay content ore?
A: El diseño estándar está optimizado para humedad seca a moderada. (arriba a 5% contenido de humedad). For highclay ore (58% humedad), we recommend the optional anticlog spider arm design and heated discharge chute. Arriba 8% humedad, a feederbreaker or sizer is more appropriate.
