1. ОТКРЫТИЕ С УПРАВЛЕНИЕМ PAINPOINT

Are you facing persistent bottlenecks in your gold ore processing circuit? Непостоянный размер корма, abrasive ore composition, and the relentless demand for throughput create significant operational hurdles. Consider the tangible costs: unplanned downtime for liner changes and repairs, excessive energy consumption from inefficient crushing, and precious metal losses due to inadequate liberation. These factors directly erode profit margins and complicate plant management.

Is premature wear on crushing components causing maintenance cycles to disrupt your production schedule?
Are you achieving optimal mineral liberation to maximize recovery in your leaching or gravity circuits?
How much potential revenue is lost due to crusher incapacity during peak feed periods?

The right primary crushing equipment is not merely a purchase; it's a strategic investment in circuit stability and metallurgical efficiency.

2. ОБЗОР ПРОДУКТА

This product line encompasses robust, highcapacity ODM Gold Ore Jaw Crushers engineered for primary crushing applications. Designed as the first critical stage in comminution, these machines reduce runofmine (ПЗУ) gold ore to a consistent, управляемый размер для последующей обработки.

Операционный рабочий процесс:
1. ROM gold ore is fed into the vibrating grizzly feeder, which bypasses subsize material and directs oversize to the crusher.
2. Ore enters the deep crushing chamber of the jaw crusher, where a powerful elliptical motion applies compressive force.
3. The material is crushed between a fixed and a moving manganese steel jaw plate.
4. Crushed product discharges at the bottom, with size determined by the closedside setting (CSS).
5. The product conveyor transports sized material to the next stage, typically secondary crushing or milling.

Область применения: Ideal for hard rock gold ores (например, quartz veins, sulphidebearing ores) in stationary plant setups or modular processing plants.
Ограничения: Не предназначен для влажной уборки., sticky ores without prior screening/scalping. Primary crushing alone does not achieve fine liberation; it prepares feed for subsequent grinding stages.

8.Часто задаваемые вопросы

вопрос:What isthe maximum recommended feed sizefor these crushers?
А:The maximum feed size should not exceed8085%of the crusher'sfeed opening width.For example,a1200x800mmcrusher can accept lumpsofup to~680mmindiameter.Optimal performanceis achievedwith wellblastedmaterialto minimize bridging.

вопрос:Canyour jaw crushers handleorewitha high clay content?
А：While capableofcrushing hard material withinclay,the presenceofsignificant sticky claycan causechamber packingand reduced capacity.We recommendprescreeningor scalpingwhere clay content exceeds10%.For severe cases,a grizzlyfeederor apron feederis essential.

вопрос:Whatisthe typical delivery lead time?
А：Lead times varyby modelcomplexityand customization.For standard tier modelsin our most popular sizes,inventoryallowsforshipmentwithin810weeks.Plantready skid packages typically require1416weeksfor fabricationand testing.Detailed schedulesare provided upon inquiry.

вопрос:Doyou provide foundation drawingsand installation supervision?
А：Yes.Comprehensive general arrangement drawings，foundation load data,and interface dimensionsare suppliedas part ofthe technical documentation.Onsite installation supervisionby our field engineersis availableas an optional service package。

вопрос：Howdoesthe quickchange wedge systemwork comparedto traditional methods？
