1. PYNPUNT GEDREWE OPENING

Are you managing a quarry operation where ballast production is a critical yet problematic link in your value chain? The challenges are familiar: inconsistent feed material causing frequent chokeups and unplanned downtime. High wear part costs from abrasive granite or basalt rapidly eroding crusher components. Inefficient particle shape control leading to excessive recirculating load and wasted capacity. Each of these issues directly impacts your bottom line through lost production hours, inflated maintenance budgets, and suboptimal yield of premiumgrade ballast.

Hoe bereik jy konsekwent, inspec railway ballast or construction aggregate while controlling operational costs? What equipment can process hard, abrasive rock with greater reliability and lower costpertonne? Die oplossing lê in die keuse van a steengroef ballas vergruis toerusting system engineered specifically for these highdemand, highabrasion applications.

2. PRODUK OORSIG

This product line comprises heavyduty primary jaw crushers and secondary cone crushers configured for optimal quarry ballast production. The operational workflow is designed for maximum uptime and shape optimization:

1. Primêre vermindering: Scalped feed material is introduced to a robust jaw crusher for initial size reduction.
2. Sekondêre verplettering & Vorming: The crushed material is conveyed to a highperformance cone crusher in closed circuit with a screening deck.
3. Grootte & Skeiding: Oversize material is recirculated back to the cone crusher, while correctly sized ballast is sent to product stockpiles.

Application scope includes the production of railway ballast, dreineringsaggregaat, and construction subbase from hard, abrasive rock types like granite, basalt, en val rots. System limitations include processing materials with excessive clay or moisture without prior washing/scalping, and feed sizes exceeding the primary crusher’s designed opening.
