1. PAINPOINT DRIVEN OPENING

Are escalating operational costs and unpredictable availability eroding your primary crushing circuit’s profitability? Plant managers and engineering contractors consistently face critical challenges with their primary crushing stations:

Unscheduled Downtime: Bearing failures or mainshaft issues can halt your entire processing line for days, costing upwards of $50,000 per hour in lost production.
High Maintenance Costs & Labor: Frequent, laborintensive liner changes and lubrication system overhauls consume both budget and skilled technician hours.
Inconsistent Throughput & Product Size: Fluctuations in feed material hardness lead to variable output, creating bottlenecks for downstream milling and processing equipment.
Excessive Energy Consumption: Older or inefficient gyratory crusher designs draw disproportionate power relative to tonnage crushed, directly impacting operational expenditure.

How do you achieve higher throughput with greater reliability while controlling total cost of ownership? The solution requires a fundamental reassessment of your primary gyratory crusher technology.

2. PRODUCT OVERVIEW: HEAVYDUTY GYRATORY CRUSHER

This heavyduty primary gyratory crusher is engineered for the continuous, hightonnage crushing of runofmine ore and blasted rock. It serves as the first mechanical reduction stage in mineral processing and aggregate production circuits.

Operational Workflow:
1. Feed: Large blasted material (up to 1.5m in size) is directed into the crushing chamber via a feed hopper.
2. Crushing Action: The eccentrically driven mainshaft causes the mantle to gyrate, creating a progressive compressive crushing action against the stationary concave liners.
3. Discharge: Crushed product exits through the discharge opening at the bottom of the chamber, with size determined by the closedside setting (CSS).

Application Scope & Limitations:
Scope: Ideal for highcapacity (2,000 10,000+ tph) primary crushing applications in largescale mining, copper, iron ore, gold operations, and major quarry sites.
Limitations: Not suitable for abrasive recycling materials without specific liner metallurgy. Requires a stable, reinforced concrete foundation and significant headroom for maintenance. Initial capital investment is substantial, justified by decades of service.
