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 operations. These include excessive, nonproductive downtime for liner changes and maintenance, leading to significant lost tonnage. Unplanned stoppages due to mechanical failures or uneven feed create costly bottlenecks downstream. Rising energy consumption per processed ton directly impacts operating margins. Furthermore, inconsistent product size distribution can hinder downstream grinding efficiency, increasing overall processing costs.

Is your current solution equipped to handle these demands? The right primary crusher is not merely a purchase; it is a longterm strategic investment in plant throughput, availability, and total cost of ownership.

2. PRODUCT OVERVIEW: GYRATORY CRUSHER

A gyratory crusher is a heavyduty, continuousduty primary crushing machine central to hightonnage mining and aggregate processing plants. Its core mechanism involves a fixed outer concave and a gyrating inner mantle mounted on an eccentric shaft, creating a progressive crushing cavity.

Operational Workflow:
1. Feed Intake: Large runofmine (ROM) ore or quarry rock is directed into the top of the crusher via dump trucks, loaders, or a feed hopper.
2. Compressive Crushing: Material enters between the mantle and concave. The gyrating motion of the mantle repeatedly compresses the rock against the stationary concave.
3. Progressive Reduction: Crushed material travels down the chamber, undergoing further size reduction with each cycle.
4. Discharge: The nowsized product exits through the bottom of the crusher (the discharge setting) onto a conveyor belt for transport to the next processing stage.

Application Scope & Limitations:
Scope: Ideal for highcapacity (1,500+ tph) primary crushing applications in largescale hard rock mining (copper, iron ore, gold), large quarry operations, and major aggregate production. Excels in abrasive materials.
Limitations: Higher initial capital cost compared to jaw crushers. Requires a substantial foundation and elevated installation for discharge clearance. Not suitable for lowtonnage operations or highly plastic/sticky materials without specialized design considerations.
