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 crusher is a single point of failure with severe financial consequences. Common challenges include:

Unscheduled Downtime: Premature wear of critical components like mantles and concaves leads to failure, causing production halts that cost tens of thousands per hour in lost throughput.
High Maintenance Costs & Labor: Frequent, manual adjustments for wear compensation are laborintensive and hazardous. The high cost and long lead times for massive replacement parts directly impact your maintenance budget.
Inconsistent Product Size: Worn or poorly configured crushers produce outofspec feed for downstream processes, reducing screening efficiency and overworking secondary crushers, which increases power consumption across the entire plant.
High Energy Consumption per Ton: An inefficiently operating gyratory crusher with poor kinematics or excessive friction can consume 1525% more power to achieve the same throughput, a direct hit to operational expenditure.

Is your operation managing these reactive costs, or is it time to invest in a primary crushing solution engineered for predictable performance and total cost of ownership?

2. PRODUCT OVERVIEW

The Industrial Gyratory Crusher remains the cornerstone of hightonnage, hardrock mining and aggregate processing operations. Designed for firststage reduction of runofmine ore or quarried rock, it delivers consistent, highcapacity crushing where jaw crushers reach their volumetric limit.

Operational Workflow:
1. Feed: Large dump trucks or loaders deposit runofmine material into the rugged feed hopper.
2. Crushing: The central vertical shaft with a mantle gyrates within a stationary concave, applying compressive force to reduce material size through progressive crushing stages.
3. Discharge: Crushed product exits through the bottom discharge opening (gape), with size controlled by the specific mantle position and stroke characteristics.

Application Scope & Limitations:
Scope: Ideal for continuous, hightonnage (1,000+ TPH) primary crushing of abrasive ores (iron, copper, gold) and hard rock (granite, basalt). Essential for largescale mining and megaquarry operations.
Limitations: Not suitable for lowtonnage applications (<500 TPH) due to high capital cost. Requires significant foundational support and elevated headroom. Less effective for highly plastic or claybound materials without prescreening.
