1. PAINPOINT DRIVEN OPENING

Are escalating operational costs and unpredictable availability eroding your primary crushing circuit's profitability? For plant managers and engineering contractors, the primary crushing stage is a critical bottleneck where failures have exponential downstream consequences. Key challenges include:

Unscheduled Downtime: Premature wear or failure of critical components like mantles, concaves, or bushings leads to production halts costing tens of thousands per hour.
High Maintenance Burden: Traditional designs require extensive labor, specialized tooling, and significant time for liner changes and routine servicing, pulling skilled personnel from other critical tasks.
Inconsistent Throughput & Product Size: Fluctuations in feed material hardness or size can cause chokefeeding or erratic discharge, compromising downstream process efficiency and final product specification.
Spiraling Operating Costs: The combined expense of replacement parts, energy consumption per ton processed, and maintenance labor directly impacts your costperton metric.

Is your current solution equipped to deliver the reliability, consistent throughput, and lower total cost of ownership required in today's competitive market? A reevaluation of your primary crushing technology is not just an equipment decision—it's a strategic financial one.

2. PRODUCT OVERVIEW

The modern China Gyratory Crusher represents a significant evolution in primary crushing technology. Engineered for highvolume, continuousduty operation in largescale mining and aggregate production, it is designed to accept runofmine feed material directly from haul trucks.

Operational Workflow:
1. Feed Acceptance: Large feed hopper receives direct dump from 200400 ton haul trucks.
2. Crushing Action: The eccentrically mounted main shaft causes the mantle to gyrate within the concave liner, applying compressive force to reduce material size.
3. Discharge: Crushed product exits through the discharge opening at the bottom of the crusher (the setting), governed by the stroke and chamber design for consistent sizing.

Application Scope & Limitations:
Scope: Ideal for highcapacity (5,000 15,000+ tph) primary crushing of abrasive ores (iron, copper, gold), hard rock aggregates, and other nonmetallic minerals. Suited for fixedplant installations.
Limitations: Not designed for smallscale operations or highly mobile applications. Requires a substantial capital investment and reinforced concrete foundation. Optimal performance requires consistent feed sizing within design parameters.
