1. ОТКРЫТИЕ С УПРАВЛЕНИЕМ PAINPOINT

Are escalating operational costs and unpredictable availability eroding your primary crushing circuit’s profitability? Для руководителей заводов и инженерных подрядчиков, 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 Common challenges with outdated or undersized gyratory crushers include:
Чрезмерное время простоя для технического обслуживания: Traditional spider bushing or mantle changes can require 2448 часы простоя производства, 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.
Непостоянная пропускная способность & Размер продукта: 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%.
Высокое энергопотребление на тонну: 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. ОБЗОР ПРОДУКТА: 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 (вогнутый) and a gyrating mantle mounted on an eccentric shaft to compress and fragment large feed material (up to 1.5m in size) against itself.

Операционный рабочий процесс:
1. Кормить: Рунофайн (ПЗУ) ore or large quarry rock is directed into the top of the crusher via dump trucks, погрузчики, or a feed hopper.
2. Сокрушительное действие: The central shaft gyrates within the concave, creating a progressive crushing cavity that reduces material size with each cycle.
3. Увольнять: Crushed material exits through the bottom of the crusher (open side setting) onto a conveyor belt for transport to the next stage of processing.

Область применения: Ideal for very high throughput applications (2,000 10,000+ т/ч), processing hard abrasive ores (железо, медь, золото) and massive aggregate rock. It is the preferred solution for stationary inpit or underground primary crushing installations.

Ограничения: Requires a substantial capital investment and reinforced concrete foundation. Не подходит для малотоннажных операций. (<1000 т/ч), highly plastic or clayrich materials, or portable plant applications where mobility is required.
