Solutions ciblées pour la production de ballast de carrière: Relever les principaux défis opérationnels

Produire des produits cohérents, le ballast ferroviaire de qualité spécifiée est une opération critique mais exigeante. Inefficient crushing directly impacts your bottom line through excessive wear part consumption, unplanned downtime for adjustments and maintenance, and high rejection rates of offspec material. Are you managing frequent liner changes on your secondary crushers? Is your current circuit struggling to maintain the strict particle shape and size distribution required by rail authorities? Are you facing escalating costs from energy consumption and premature equipment failure in your aggregate processing line? The right primary crushing equipment sets the foundation for resolving these issues.

Présentation du produit: HeavyDuty Primary Jaw Crusher for Ballast Production

Cette gamme de produits comprend une série de robustes, stationary and mobile primary jaw crushers engineered specifically for the initial reduction of blasted quarry rock into feed suitable for secondary ballast crushing circuits. Le flux de travail opérationnel est simple: 1) blasted feed material is directed into the vibrating grizzly feeder, 2) oversize material enters the crushing chamber where a highinertia flywheel and optimized kinematics facilitate forceful compression breakage, 3) crushed product is discharged at a preset CSS (Réglage du côté fermé) onto a main conveyor. These units are designed for hard rock (granit, basalte, piège à pierres) applications with an unconfined compressive strength (SCU) of up to 350 MPa. They are not intended as standalone finishing units but as the first critical stage in a multistage ballast crushing plant.

Scénarios d'application

Carrière Hard Rock approvisionnant le projet ferroviaire national

Défi: A granite quarry winning a major rail contract faced inconsistent fragmentation from blasting, causing frequent plugging and excessive wear in their existing primary crusher, jeopardizing delivery schedules.
Solution: Implementation of a heavyduty jaw crusher with an aggressive stroke profile and integrated prescreen grizzly to handle slabby rock.
Résultats: Throughput stabilized at design capacity of 550 TPH. Downtime from clearing blockages was eliminated. First set of jaw dies achieved 195,000 tonnes before changeout.

Un producteur de granulats se développe sur le marché du ballast ferroviaire

Défi: A producer needed to modify their existing plant to produce ballast without compromising their core aggregate products. Their main constraint was limited space for expansion.
Solution: A compact mobile primary jaw crushing unit was installed as a dedicated ballast line starter, allowing quick reconfiguration between standard aggregate and ballast production.
Résultats: The site can now switch to ballast production within one shift. The cubical product from the new primary unit reduced wear on the existing downstream cone crusher by an estimated 30% when processing ballast.
