1. APERTURA IMPULSADA POR EL PUNTO DE DOLOR

Are you managing a quarry operation where inconsistent ballast production is impacting your bottom line? The challenges of producing railway ballast to exacting specifications—while controlling costs—are significant. Los obstáculos operativos comunes incluyen:
Generación excesiva de multas: Arriba a 1520% of processed material can fall below the required gradation, turning potential revenue into waste stockpile.
Tiempo de inactividad no planificado: Frequent liner changes and component wear in standard crushers lead to 4060 hours of lost production annually for maintenance.
Product Shape Inconsistency: Poor cubicity and excessive flaky particles in the final product can lead to rejection by rail authorities, requiring recrushing and delaying shipments.
Altos costos operativos: Energyintensive processes and rapid wear part consumption directly erode profit margins per ton.

How do you increase yield of specification ballast, extend mean time between failures, y garantizar una coherencia, highquality product that meets stringent rail network standards?

2. DESCRIPCIÓN GENERAL DEL PRODUCTO

This content details engineered solutions for ISO Certified Quarry Ballast Crushing Equipment. Específicamente, we focus on heavyduty cone crushers and vertical shaft impactors (VSI) configured for tertiary and quaternary crushing stages, where precise shaping and sizing of railway ballast is critical.

The operational workflow for optimal ballast production typically involves:
1. Primary jaw crushing of blasted feed material to 250mm.
2. Secondary cone crushing to produce a 75mm base feed.
3. Tertiary/Quaternary Processing: The featured equipment takes the secondary feed, employing specialized crushing chambers and rotor configurations to fracture rock along natural lines.
4. Precision screening on multideck screens to isolate the 31.563mm (or local standard) ballast fraction.
5. Recirculation of oversize and crusher fines for further processing or separation.

Ámbito de aplicación: Ideal para roca dura (granito, basalto) and abrasive quarries dedicated to producing EN 13450, AREMA, or other national railway ballast standards. Limitations include processing highly weathered or claybound materials without prior washing and classification.

6. ESCENARIOS DE APLICACIÓN

Cantera de granito suministra proyecto ferroviario nacional

Desafío: A major infrastructure project required 500,000 tonnes of Type A ballast meeting strict flakiness index limits. The existing tertiary crusher produced excessive elongated particles (>22%), causing high recirculation loads and bottlenecking the screening plant.
Solución: Implementation of a configured cone crusher with a specialized "lastre" crushing chamber profile and automated setting control.
Resultados: Flakiness index improved from >22% a <15%. El rendimiento de la planta aumentó en 22%, enabling the project delivery schedule to be met ahead of time.

Basalt Quarry Seeking Cost Reduction
