1. PAINPOINT DRIVEN OPENING

Are you managing crushing operations where equipment reliability, material purity, and regulatory compliance directly impact your bottom line? Consider these common operational challenges:

Unplanned Downtime from Component Failure: Frequent breakdowns of wear parts in highimpact zones lead to inconsistent throughput and costly, reactive maintenance schedules.
Contamination Risks in Sensitive Applications: When processing materials for electronics, pharmaceuticals, or highgrade ceramics, metallic contamination from crusher wear can compromise entire batches and result in product rejection.
Compliance Overhead and Market Access Barriers: Exporting machinery or processed materials to the EU, North America, and other regulated markets requires verifiable RoHS compliance. Noncompliant equipment can block market entry and incur penalties.
High Lifetime Cost of Consumables: Standard manganese steel hammers, liners, and impeller bars not only wear quickly but also require rigorous documentation to prove they are free from restricted substances with each batch.

How can you achieve the required particle reduction while ensuring your process chain is verifiably clean and compliant? What if your impact crusher could be a documented asset for market access rather than a compliance risk?

2. PRODUCT OVERVIEW: RoHS Compliant Impact Crushers

A RoHS Compliant Impact Crusher is a heavyduty reduction machine engineered to fragment rock, concrete, or industrial minerals via highspeed impact, constructed entirely with materials that adhere to the Restriction of Hazardous Substances (RoHS) Directive (2011/65/EU). This ensures the equipment—and by extension, the processed material—contains no lead, cadmium, mercury, hexavalent chromium, PBB, or PBDE above permitted thresholds.

Operational Workflow:
1. Feed Intake: Material is fed into a robust housing containing a highspeed rotor.
2. Acceleration & Impact: The rotor hurls material against stationary anvils or breaker plates; size reduction occurs through kinetic energy transfer.
3. Particle Liberation: Fractured material is ejected back into the impact curtain for further reduction or sized via adjustable gap settings.
4. Graded Discharge: Crushed product exits through the bottom grating, with final sizing controlled by the gap between rotor and impact apron.

Application Scope: Ideal for secondary and tertiary crushing of limestone, recycled concrete aggregate (RCA), construction waste, glass cullet, and specialty minerals where endproduct purity is critical. Essential for plants supplying aggregates for sensitive industrial processes or exporting to regulated markets.

Limitations: Not designed as primary crushers for very large feed (typically >500mm). Maximum hardness is constrained by the available grades of compliant wear alloys; may not be suitable for continuous crushing of highly abrasive igneous rock without accelerated wearpart consumption.
