1. PYNPUNT GEDREWE OPENING

Die bestuur van 'n ystererts-breekkring bied duidelik, duur uitdagings. Are you experiencing persistent bottlenecks that limit your plant’s rated throughput? Are unscheduled maintenance stops and premature wear part failures eroding your operating budget and creating unpredictable downtime? Is inconsistent product sizing leading to inefficiencies in downstream grinding and processing, ultimately affecting pellet or sinter quality? Verder, does the total cost of ownership for your primary crushing stage—factoring in energy consumption, voering vervangings, and labor—exceed initial projections? These operational hurdles directly impact profitability. Die sentrale vraag vir aanlegbestuurders is dit: hoe kan jy betroubare bereik, hightonnage reduction of abrasive iron ore while controlling operational costs and maximizing plant availability?

2. PRODUK OORSIG

Hierdie produk is 'n Primêre Giratory Breker engineered specifically for highcapacity iron ore processing. It is designed as the first critical stage in a mineral processing plant, receiving runofmine (ROM) feed directly from the pit.

Operasionele werkvloei:
1. Voerinname: ROM ystererts (tot 1,5 m knopgrootte) is dumped into the crusher’s deep, nonchoking receiving hopper.
2. Verpletterende Aksie: A centrally mounted mantle gyrates within a concave bowl, applying compressive force to break the ore against itself.
3. Ontslag: Crushed material exits through the bottom setting (CSS), with product size typically ranging from 150mm to 250mm for feed to secondary crushing or SAG mill circuits.

Toepassingsomvang & Beperkings:
Omvang: Ideal for largescale mining operations with high daily tonnage requirements (>10,000 MTD). Suited for processing hard, abrasive hematite and magnetite ores.
Beperkings: Not designed for final product sizing or for processing materials with high clay or moisture content without adequate prescreening/scalping. Vereis 'n stabiele betonfondasie en aansienlike kopruimte vir installering en instandhouding.

6. TOEPASSINGSSCENARIO'S

LargeScale Open Pit Mine – Australia Challenge:

A major hematite operation faced declining feed grades, requiring higher throughput volumes through their primary crushing station to maintain annual production targets. Their existing crusher was unable to achieve higher tonnage without excessive wear and energy costs.

Oplossing:

Implementation of one PGC60110 Primary Gyratory Crusher with the integrated automatic setting system.

Resultate:

Within six months of commissioning:
Sustained throughput increased by 18%, meeting upgraded plant demands.
Energy cost per ton crushed decreased by 16%.
Annual planned maintenance hours were reduced by 120 hours due to extended liner intervals.

Magnetite Concentrator – North America Challenge:

The client’s new greenfield project required a primary crusher capable of handling extremely hard magnetite ore while guaranteeing >95% availability as the single point of failure for the entire coarse ore circuit.

Oplossing:

Installation of two PGC60110 crushers configured with full condition monitoring on lube systems and main bearings.
