1. OUVERTURE ENTRAÎNÉE PAR POINT DE DOULEUR

Gérez-vous une exploitation de carrière où la production est constante, highquality railway ballast is compromising your profitability? Les défis sont spécifiques et coûteux. 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, temps d'arrêt imprévu, arrêter toute votre chaîne de production. Rising energy costs are eroding margins on what should be a highvolume commodity. En outre, 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? La solution nécessite un équipement conçu non seulement pour le concassage, but for optimized ballast production with verifiable material integrity.

2. APERÇU DU PRODUIT

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).

Flux de travail opérationnel:
1. Réduction primaire: Matière première (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. Dimensionnement & Suppression des amendes: The crushed output is screened via a multideck screen; oversized material is recirculated (circuit fermé), while undersize fines are diverted to enhance the yield of the target ballast fraction.
4. Manutention du produit final: Specification ballast is conveyed to stockpile, with system controls documenting batch data for compliance reporting.

Champ d'application: Idéal pour les carrières de roches dures (granit, basalte, piège à pierres) producing aggregates for railway construction and maintenance projects requiring RoHS compliance.
Limites: Non conçu pour les roches tendres ou très friables (par ex., limestone below 150 Résistance à la compression MPa) where excessive fines generation would occur via this method; primary feed size is limited by model selection.
