1. PAINPOINT DRIVEN OPENING

Are escalating maintenance costs and unplanned downtime eroding your primary crushing circuit's profitability? Operational managers face persistent challenges with their primary gyratory crushers, including premature wear of critical components, inconsistent feed opening performance leading to bottlenecks, and excessive energy consumption per ton of processed material. These issues directly translate to high liner replacement costs, lost production hours during servicing, and suboptimal throughput that constrains entire downstream operations. How can you achieve higher availability, reduce your costperton metric, and ensure consistent feed size for your SAG or ball mill feeders? A modern, precisionengineered gyratory crusher is engineered to address these exact operational and financial pressures.

2. PRODUCT OVERVIEW

The modern heavyduty gyratory crusher is a stationary primary crushing machine designed for highcapacity size reduction of runofmine ore or blasted rock. Its core function is to accept large feed material (typically up to 1500mm) and reduce it to a conveyable product, often between 150300mm, at rates exceeding 10,000 metric tons per hour.

Operational Workflow:
1. Feed: Dump trucks or loaders deposit material into the crusher’s feed hopper.
2. Crushing: The central vertical shaft with a mantle gyrates within a stationary concave liner, applying compressive force to break the rock.
3. Discharge: Crushed material falls by gravity through the increasing gap at the bottom of the chamber onto a conveyor belt for transport to the next processing stage.

Application Scope & Limitations:
Scope: Ideal for hightonnage mining operations (copper, iron ore, gold), largescale aggregate quarries, and major industrial mineral processing plants requiring continuous, reliable primary crushing.
Limitations: Not suitable for smallscale operations or highly abrasive recycling materials without specific configurations. Requires a substantial capital investment and a stable, reinforced concrete foundation. Operational flexibility for product size adjustment is generally lower than jaw crushers.
