1. APERTURA IMPULSADA POR EL PUNTO DE DOLOR

¿Está usted administrando una operación de cantera donde la producción constante, highquality railway ballast is compromising your profitability? Los desafíos son específicos y costosos.. Noncompliant ballast leads to rejection and costly rework, while excessive fines generation directly reduces your saleable product yield. Frequent liner changes in your crushing chamber cause extended, tiempo de inactividad no planificado, detener toda su línea de producción. Rising energy costs are eroding margins on what should be a highvolume commodity. Además, increasing regulatory and tender requirements for RoHS compliance add a layer of complexity to material sourcing and documentation.

How do you increase throughput of specification ballast while controlling operational costs? Can your crushing equipment handle hard, abrasive rock without sacrificing particle shape or availability? Is your current setup configured to maximize yield of the 2565mm fraction while minimizing waste? The solution requires equipment engineered not just for crushing, but for optimized ballast production with verifiable material integrity.

2. DESCRIPCIÓN GENERAL DEL PRODUCTO

This product line comprises stationary and semimobile primary jaw crusher and secondary cone crusher configurations engineered specifically for RoHS compliant quarry ballast crushing. The system is designed to transform blasted rock into certified railway ballast that meets EN 13450, AREMA, or other regional specifications, with full traceability for hazardous substance compliance (RoHS Directive 2011/65/EU).

Flujo de trabajo operativo:
1. Reducción Primaria: Material de alimentación (typically 0700mm) is crushed in a heavyduty jaw crusher to a nominal 0250mm product.
2. Secondary Precision Crushing: The primary product is conveyed to a dedicated cone crusher configured with a specific chamber profile and stroke for optimal interparticle crushing.
3. Apresto & Eliminación de multas: The crushed output is screened via a multideck screen; oversized material is recirculated (circuito cerrado), while undersize fines are diverted to enhance the yield of the target ballast fraction.
4. Manipulación del producto final: Specification ballast is conveyed to stockpile, with system controls documenting batch data for compliance reporting.

Ámbito de aplicación: Ideal para canteras de roca dura (granito, basalto, trampa de roca) producing aggregates for railway construction and maintenance projects requiring RoHS compliance.
Limitaciones: No diseñado para rocas blandas o muy friables. (p.ej., limestone below 150 Resistencia a la compresión MPa) where excessive fines generation would occur via this method; primary feed size is limited by model selection.
