1. PYNPUNT GEDREWE OPENING

Are escalating operational costs and unpredictable availability eroding your primary crushing circuit’s profitability? Vir aanlegbestuurders en ingenieurskontrakteurs, the primary crushing stage is a critical bottleneck where inefficiencies cascade downstream, directly impacting tonnage and bottom line. Common challenges with outdated or undersized gyratory crushers include:
Oormatige stilstand vir instandhouding: Traditional spider bushing or mantle changes can require 2448 ure se verlore produksie, costing thousands per hour in idle processing capacity.
Unplanned Stoppages from Tramp Iron: Inadequate protection mechanisms lead to costly damage to head nuts, mainshafts, and bushings, resulting in sixfigure repair bills and extended outages.
Inkonsekwente deurset & Product Size: Worn or poorly designed crushing chambers fail to maintain target discharge settings, causing fluctuations in feed to downstream SAG mills or secondary crushers, reducing overall plant efficiency by 515%.
Hoë energieverbruik per ton: Inefficient crushing action and high friction points force drives to work harder, increasing power costs—often the single largest operating expense.

Is your operation equipped to handle harder ores and higher tonnage demands while controlling maintenance costs and maximizing uptime?

2. PRODUK OORSIG: GYRATORY CRUSHER

A gyratory crusher is a cornerstone of highcapacity primary crushing stations in mining and largescale aggregate operations. It utilizes a fixed conical shell (concave) and a gyrating mantle mounted on an eccentric shaft to compress and fragment large feed material (up to 1.5m in size) against itself.

Operasionele werkvloei:
1. Voer: Runofmyne (ROM) ore or large quarry rock is directed into the top of the crusher via dump trucks, laaiers, or a feed hopper.
2. Verpletterende Aksie: The central shaft gyrates within the concave, creating a progressive crushing cavity that reduces material size with each cycle.
3. Ontslag: Crushed material exits through the bottom of the crusher (open side setting) onto a conveyor belt for transport to the next stage of processing.

Toepassingsomvang: Ideal for very high throughput applications (2,000 10,000+ tph), processing hard abrasive ores (yster, koper, goud) and massive aggregate rock. It is the preferred solution for stationary inpit or underground primary crushing installations.

Beperkings: Requires a substantial capital investment and reinforced concrete foundation. Nie geskik vir laetonnage-operasies nie (<1000 tph), highly plastic or clayrich materials, or portable plant applications where mobility is required.
