1. PAINPOINT DRIVEN OPENING

Are escalating operational costs and unpredictable availability eroding your primary crushing circuit’s profitability? Key challenges in gyratory crusher operation directly impact your bottom line:
Unscheduled Downtime: Bearing failures or mainshaft issues can halt entire processing plants for days, costing hundreds of thousands in lost production.
High Maintenance Costs: Frequent, laborintensive liner changes and component rebuilds consume both budget and critical manpower.
Inconsistent Throughput & Product Quality: Worn or poorly designed crushing chambers lead to fluctuating product gradation and reduced capacity, bottlenecking downstream processes.
Excessive Energy Consumption: Inefficient crushing action and highfriction components result in unsustainable power draw per ton of material processed.

Is your operation managing these recurring issues, or is it time for a crusher engineered to deliver reliability, efficiency, and longterm cost control?

2. PRODUCT OVERVIEW

The Premium Gyratory Crusher represents the pinnacle of primary crushing technology for hightonnage, hardrock mining and aggregate operations. Engineered for continuous, heavyduty service, it is the optimal solution for the initial reduction of runofmine ore or large quarry stone.

Operational Workflow:
1. Feed Intake: Large dump trucks or loaders deposit feed material directly into the crusher’s robust feed hopper.
2. Crushing Action: The hydraulically supported mainshaft assembly gyrates within a concave crushing chamber, applying compressive force to break material against the chamber walls.
3. Product Discharge: Crushed material exits through the discharge opening at the bottom of the chamber, with size controlled by the closedside setting (CSS).

Application Scope & Limitations:
Scope: Ideal for primary crushing applications with feed sizes up to 1500mm, requiring capacities from 2,000 to over 10,000 t/h. Suited for abrasive ores (copper, gold, iron) and hard rock aggregates.
Limitations: Not designed for recycled concrete/asphalt or highly plastic/claybound materials. Requires significant capital investment and a stable, reinforced concrete foundation.

6. APPLICATION SCENARIOS

LargeScale Copper Mine Expansion

Challenge: A planned plant expansion required a primary crusher capable of sustaining >8,000 t/h on highly abrasive porphyry ore while fitting within tight space constraints of an existing pit layout.
Solution: Installation of a single Premium Gyratory Crusher with a compact "spiderless" design profile.
Results: Achieved sustained throughput of 8,400 t/h with product P80 consistently below required spec. Liner life exceeded projections by 15%, contributing to a calculated payback period under three years versus alternative solutions.

HighProduction Granite Quarry

Challenge: Frequent weekend liner changes were creating production bottlenecks. Unpredictable bearing temperatures led to two unscheduled stoppages in one year.
Solution: Implementation of a midrange Premium Gyratory Crusher featuring the TopService Concept and Intelligent Control System.
Results:Liner change time reduced from three shifts to one shift (8 hours). The monitoring system provided early warning on lube system health, preventing a potential bearing failure. Annual availability increased to 96.8%.
