1. PYNPUNT GEDREWE OPENING

Are escalating operational costs and unpredictable availability eroding your primary crushing circuit’s profitability? Key challenges in primary crushing often include:

Ongeskeduleerde stilstand: Bearing failures or mainshaft issues can halt your entire processing line, kos tienduisende per uur in verlore produksie.
Hoë instandhoudingskoste: Gereeld, laborintensive liner changes and component wear directly impact your maintenance budget and manpower allocation.
Inkonsekwente deurset: Fluctuations in feed size or hardness can cause chokefed conditions or poor cavity utilization, failing to meet designed tonnage targets.
Product Quality Issues: Poorly controlled discharge settings lead to offspec product size distribution, placing undue stress on downstream screening and secondary crushing stages.

How do you achieve consistent, hightonnage reduction of runofmine material while controlling total cost of ownership? The solution lies in selecting a gyratory crusher engineered not just for capacity, but for reliability and operational efficiency.

2. PRODUK OORSIG: GYRATORY BRUSKER

A gyratory crusher is a stationary primary compression crusher, central to largescale mining and aggregate operations. It utilizes a gyrating mantle within a concave hopper to progressively reduce large feed material (typically up to 1.5m in size) to a manageable product for conveyor transport to downstream processes.

Operasionele werkvloei:
1. Voerinname: Runofmine ore or quarry rock is dumped directly from haul trucks into the topmounted feed hopper.
2. Progressive Compression: The central mantle gyrates eccentrically within the fixed concave liners, continuously compressing and fracturing material as it travels down the crushing chamber.
3. Ontslag: Gebreekte materiaal gaan deur die afvoeropening aan die onderkant uit, with size primarily controlled by the vertical position of the mantle.

Toepassingsomvang & Beperkings:
Omvang: Ideaal vir hoë kapasiteit (1,000 10,000+ tph) primary crushing applications with abrasive, hard ores (bv., koper, yster, goud) or hard rock aggregates. Suited for continuous operation with direct truck or shovel feeding.
Beperkings: Higher capital cost than comparable jaw crushers. Requires a stable, reinforced concrete foundation. Not suitable for lowtonnage operations or highly plastic/sticky materials without modification.
