1. PAINPOINT DRIVEN OPENING

Are escalating operational costs and unpredictable availability eroding your primary crushing circuit’s profitability? For plant managers and engineering contractors, the primary crushing stage is a critical bottleneck where inefficiencies cascade through the entire downstream process. Common challenges with traditional gyratory crushers include:
Excessive Downtime for Maintenance: Scheduled mantle and concave changes can take 2472 hours, with unscheduled downtime due to premature wear or mechanical issues costing upwards of $50,000 per day in lost production.
High Operational Costs: Rising energy consumption, coupled with the high cost and frequency of replacing massive wear parts, directly impacts your costperton metric.
Inconsistent Product Size: Worn or poorly adjusted crushers produce offspec feed for secondary circuits, reducing throughput and recovery rates in milling operations.
LaborIntensive Monitoring: Reliance on manual checks for wear and performance leads to reactive maintenance, increasing the risk of catastrophic failure.

What if your primary crusher could deliver higher throughput with lower energy consumption, extend maintenance intervals by 3040%, and provide actionable data to shift from reactive to predictive upkeep? The solution lies in a modern, customized gyratory crusher designed for your specific ore characteristics and operational goals.

2. PRODUCT OVERVIEW: CUSTOMIZED GYRATORY CRUSHER

A gyratory crusher is a cornerstone of highcapacity primary crushing stations in largescale mining and aggregate operations. It utilizes a gyrating mantle within a concave housing to compress and fragment large feed material (often exceeding 1.5 meters) into a smaller, consistent product for downstream processing.

Operational Workflow:
1. Feed Intake: Runofmine (ROM) ore or quarry rock is directed into the top of the crusher via a dump pocket or feeder.
2. Compressive Crushing: The central mantle gyrates within the stationary concave liner, continuously compressing material against the chamber walls.
3. Progressive Reduction: Material fractures and moves down the chamber through multiple crushing zones (primary, secondary), becoming progressively smaller.
4. Discharge: Crushed product exits through the discharge opening at the bottom, with size controlled by the closedside setting (CSS).

Application Scope & Limitations:
Scope: Ideal for hightonnage (2,000 10,000+ tph) applications requiring primary reduction of hard, abrasive ores (e.g., copper, iron, gold) or massive aggregate rock. Suited for stationary installations with direct dump from large haul trucks.
Limitations: Not suitable for lowtonnage operations (<1000 tph) due to high capital cost. Requires significant foundational support and infrastructure. Less effective for highly plastic or claybound materials that may cause packing.
