1. PAINPOINT DRIVEN OPENING

Are escalating operational costs and unpredictable availability eroding your primary crushing circuit’s profitability? Plant managers and engineering contractors face persistent challenges in gyratory crusher performance that directly impact the bottom line. These include:
Unscheduled Downtime: Bearing failures or mainshaft issues can halt production for days, costing hundreds of thousands in lost throughput.
High Maintenance Costs: Frequent, laborintensive liner changes and component wear consume both budget and skilled manpower.
Inconsistent Throughput & Product Size: Worn or poorly designed crushing chambers lead to fluctuating gradation, downstream bottlenecks, and reduced product quality.
Energy Inefficiency: Older or suboptimized designs consume excessive power per ton of processed material, a significant fixed cost.
Structural Integrity Concerns: Fatigue in the lower frame or spider assembly poses longterm reliability risks.

Is your operation equipped to overcome these challenges with a crusher built for maximum uptime, engineered precision, and certified quality? The solution lies in specifying an ISOcertified gyratory crusher from an OEM factory.

2. PRODUCT OVERVIEW

The ISO Certified Gyratory Crusher is a primary crushing machine designed for highcapacity, continuous size reduction of runofmine ore or blasted rock. Its core function is to accept large feed material (typically up to 1.5m) and reduce it to a conveyable product for secondary crushing circuits.

Operational Workflow:
1. Feed Intake: Material is fed into the crushing chamber from above via a feed hopper and distributed by the spider.
2. Crushing Action: The mantle gyrates within the concave liners, applying compressive force to crush rock against itself (interparticle crushing).
3. Discharge: Crushed material falls by gravity through the decreasing gap at the bottom of the chamber and is discharged onto the main conveyor.

Application Scope:
Ideal for largescale mining operations (copper, iron ore, gold), hightonnage aggregate quarries, and major industrial mineral processing plants requiring >1,000 mtph capacity.
Suited for abrasive and hard rock applications.

Limitations:
Higher capital cost compared to primary jaw crushers.
Requires a stable, substantial foundation due to its weight and dynamic loads.
Not suitable for lowtonnage operations or highly plastic/sticky materials without specific design considerations.
