1. PAINPOINT DRIVEN OPENING

Are you managing unpredictable throughput, escalating liner replacement costs, or unplanned downtime in your primary crushing circuit? Inconsistent feed size, abrasive ores, and the demand for precise product sizing place immense pressure on your operation’s bottom line. Consider these common challenges:
Unscheduled Downtime: Premature wear or failure of critical components can halt your entire processing line, costing tens of thousands per hour in lost production.
High Maintenance Costs: Frequent liner changes and component rebuilds consume both labor hours and spare parts budgets, directly eroding profit margins.
Inconsistent Product Size: Fluctuations in discharge setting lead to poor downstream performance, reducing grinding efficiency and final recovery rates.
Rising Energy Costs: An inefficient crushing motion or suboptimal speed can lead to excessive power draw per ton of processed material.

How can you achieve greater operational predictability, reduce cost per ton, and ensure your primary crusher is a reliable asset rather than a recurring liability? The specification of your CE Marked Gyratory Crusher is the foundational decision that addresses these issues.

2. PRODUCT OVERVIEW

A CE Marked Gyratory Crusher is a heavyduty, continuousduty primary crushing machine designed for the initial size reduction of runofmine ore or blasted rock. Its core mechanism involves a gyrating mantle within a concave crushing chamber, delivering high capacity and a progressive crushing action ideal for hard, abrasive materials.

Operational Workflow:
1. Feed Intake: Large feed material from the mine is directed into the top of the crusher’s deep, unrestricted opening.
2. Progressive Crushing: The eccentrically gyrating mantle continuously compresses material against the stationary concaves, breaking it through multiple stages within the chamber.
3. Discharge: Crushed product exits through the discharge opening at the bottom, with size controlled by the vertical position of the mantle.

Application Scope: Best suited for hightonnage mining operations (typically >1,000 tph), quarries with hard rock, and largescale mineral processing plants requiring reliable primary reduction.
Limitations: Not designed for lowcapacity applications or recycling/secondary crushing circuits where smaller jaw or cone crushers are more appropriate. Requires a substantial capital investment and reinforced plant infrastructure.
