Subject: Addressing Iron Ore Crushing Cost Overruns & Compliance Risks – RoHS Compliant Factory Direct Pricing

1. PAINPOINT DRIVEN OPENING

Are escalating energy costs and frequent liner replacements eroding your iron ore processing margins? Do environmental compliance audits for heavy metal content in wear parts threaten to halt your production line? Industry data indicates that noncompliant crushing equipment can lead to 1520% higher maintenance expenditure due to accelerated corrosion and unexpected downtime. Furthermore, failing RoHS (Restriction of Hazardous Substances) standards can result in fines exceeding $50,000 per incident and supply chain rejection from downstream steel mills.

Your current setup may be facing three critical challenges:

• Wear Part Toxicity: Standard manganese steel often contains lead or cadmium additives that violate export regulations.
• Throughput Bottlenecks: Inefficient chamber design leads to recirculating loads of 30% or more, wasting power.
• Total Cost of Ownership (TCO): Frequent bearing failures due to inadequate dust sealing increase unplanned stoppages by 812 hours per month.

How can you secure a crushing line that meets international environmental standards without a 40% premium on capital expenditure?

2. PRODUCT OVERVIEW

The RoHS Compliant Iron Ore Crushing Plant is a stationary or semimobile primary and secondary reduction system engineered specifically for highabrasion, highcompressivestrength feed materials (up to 350 MPa). This plant integrates a jaw crusher and a cone crusher, utilizing leadfree, cadmiumfree metallurgy in all wear components.

Operational Workflow:
1. Feed Hopper & Grizzly Feeder: Runofmine ore (up to 800mm) is fed via a vibrating grizzly, scalping fines (150mm) to reduce jaw wear.
2. Primary Jaw Crushing: Ore is reduced to 150200mm using a deepchamber, overhead eccentric jaw with RoHScompliant manganese liners.
3. Secondary Cone Crushing: Material is conveyed to a heavyduty cone crusher with hydraulic adjustment, achieving a final product of 040mm for ball mill feed.
4. Vibrating Screen: Closedcircuit screening ensures oversize material is returned to the cone crusher, maintaining a consistent P80 size.

Application Scope: Suitable for hematite, magnetite, and mixed iron ore types. Limitations: Not designed for wet, sticky claybound ores exceeding 15% moisture without a scrubbing pretreatment stage.

8. FAQ

Q: Is the RoHS certification verified by a third party?
A: Yes. All wear parts are supplied with a material test certificate (MTC) from an ISO 17025 accredited lab, confirming lead content below 0.01% and cadmium below 0.005%.

Q: Can this plant handle highsilica iron ore (SiO2 > 15%)?
A: Yes. The NiCrMo alloy liners are designed for high abrasion. However, we recommend a prescreening stage to remove fines and reduce wear rate. Field data shows a 20% increase in liner life compared to standard Mn18Cr2.

Q: What is the typical lead time for a 200 TPH plant?
A: Standard lead time is 812 weeks from order confirmation, depending on customization. Expedited delivery (6 weeks) is available for standard packages.

Q: Does the plant require a concrete foundation?
A: Yes, a reinforced concrete foundation is recommended for stationary installations. We provide foundation drawings and anchor bolt templates. Semimobile options with steel skids are available for rental operations.

Q: How does the hydraulic tramp release system work?
A: If an uncrushable object enters the cone crusher, hydraulic pressure spikes. The accumulator absorbs the shock, allowing the bowl to lift and pass the object. The system resets automatically within 30 seconds.

Q: What is the warranty on the main frame?
A: The main frame (fabricated steel) carries a 5year warranty against manufacturing defects. Wear parts are warranted for 1,000 hours or 6 months, whichever comes first.

Q: Can I retrofit RoHS liners to my existing crusher?
A: Yes, we offer customcast RoHS liners for most major OEM crusher models (Metso, Sandvik, Terex). Contact our engineering team with your crusher model and chamber profile for a quote.
