1. PAINPOINT DRIVEN OPENING

Are you managing crushing operations where equipment reliability, consistent product gradation, and total cost of ownership directly determine profitability? For plant managers and engineering contractors, the challenges with primary crushing are quantifiable. Unplanned downtime for mantle or concave replacement can halt an entire processing line, costing tens of thousands per hour in lost production. Inconsistent feed size or moisture content can lead to choking, reducing throughput and increasing power consumption per ton. Furthermore, the global push for responsible manufacturing means sourcing equipment that complies with environmental directives like RoHS is no longer optional but a prerequisite for many projects and tenders.

How do you achieve higher availability with lower maintenance labor? Can your primary crusher deliver a consistent product curve despite variable feed? Are your equipment partners providing verifiable compliance documentation for hazardous substance control? The solution lies in specifying a RoHS Compliant Gyratory Crusher from a manufacturer committed to both performance and material integrity.

2. PRODUCT OVERVIEW

A RoHS Compliant Gyratory Crusher is a primary crushing machine designed for highcapacity, continuous operation in largescale mining and aggregate operations, built with strict adherence to the Restriction of Hazardous Substances (RoHS) directive. This governs the use of specific hazardous materials in electrical components and certain mechanical alloys.

Operational Workflow:
1. Feed Intake: Large runofmine ore or quarry rock is directly dumped into the crusher’s receiving hopper above the spider assembly.
2. Crushing Action: The gyrating mantle eccentrically compresses material against the stationary concave liners, applying progressive compressive force to break particles.
3. Discharge: Crushed material falls by gravity through the decreasing gap at the bottom of the chamber and exits through the discharge opening.

Application Scope: Ideal for hightonnage (1,500+ tph) primary crushing stations handling abrasive ores (iron, copper, gold) and hard rock. It is the preferred solution for slabby feed material due to its nonchoking design.

Limitations: Higher capital cost compared to jaw crushers; requires a substantial and stable foundation due to weight and dynamic forces; not suitable for portable plants or lowtonnage operations.

3. CORE FEATURES

6. APPLICATION SCENARIOS

Copper Mine Expansion Project – Primary Crushing Circuit

Challenge: An existing SAG mill feed circuit was bottlenecked by an aging primary crusher with frequent liner failures and excessive energy use (~0.85 kWh/t). The project had strict EUderived environmental procurement rules.
Solution: Installation of a new midsize RoHS Compliant Gyratory Crusher featuring smart chamber geometry and highefficiency drives.
Results: Throughput increased by 18% while specific energy consumption dropped to 0.76 kWh/t. The provided full material compliance dossier satisfied the project’s green procurement requirements without delay.

Granite Aggregate Producer – HighAbrasion Quarry

Challenge: Extremely abrasive granite was causing concave liner life of only 4 months in a standard gyratory crusher, leading to high consumable costs and unpredictable downtime.
Solution: Implementation of a heavyduty RoHS Compliant Gyratory Crusher configured with proprietary chromemoly liners and an optimized peripheral spray system to reduce dust without accelerating liner wear.
Results: Liner service life extended to over 6 months—a 50% improvement—reducing annual consumable spend by approximately onethird while maintaining consistent 8” product sizing.

Iron Ore Processing Plant – Capacity Upgrade

Challenge: Need to increase plant capacity by >25%. Existing footprint was constrained; new equipment had to interface seamlessly with existing conveyors while offering higher reliability metrics.
Solution: A highcapacity RoHS Compliant Gyratory Crusher was selected based on its superior availability (>94%) metrics from field data in similar applications.
Results: The crusher met all throughput targets within the existing footprint constraints. Plantwide availability improved due to reduced primary crushing section downtime, contributing directly to achieving annual production goals.
