Commercial Stone Crusher Machine Trading Company

1. OUVERTURE ENTRAÎNÉE PAR POINT DE DOULEUR

Your quarry or construction site is losing an estimated $2,500 per hour of unscheduled downtime. Are your current crushing circuits struggling to maintain a consistent output of 20mm aggregate, forcing costly recrushing cycles? Do you face escalating wear costs due to high silica content in your feed material, eroding your profit margins by 1520% annuellement? Are you managing a fleet of older, singlestage crushers that cannot meet the strict flakiness index requirements for highspec asphalt or concrete production? Plant managers report that inconsistent feed gradation from primary crushers leads to a 1012% reduction in downstream screening efficiency. La question est: can your current equipment handle the throughput demands of a 300tonperhour commercial operation without compromising product quality or operator safety?

2. APERÇU DU PRODUIT

Le Commercial Stone Crusher Machine is a multistage, electricallydriven crushing system designed for continuous, highvolume aggregate production. It is engineered for the secondary and tertiary reduction of hard rock (granit, basalte, piège à pierres) and river gravel into commercialgrade construction aggregates.

Flux de travail opérationnel:
1. Consommation alimentaire: Matériel (100300mm) is fed via a vibrating grizzly feeder, qui supprime les amendes (40mm) to bypass the primary crushing chamber, réduire l'usure.
2. Réduction primaire: Material enters the highchamber jaw crusher for initial compression reduction to 100150mm.
3. Concassage secondaire: Oversized material is conveyed to a cone crusher or impact crusher for controlled reduction to 5080mm.
4. Façonnage tertiaire: Material passes through a vertical shaft impact (TOUT LE MONDE) crusher for cubical shaping and final sizing to 020mm.
5. Dépistage & Classification: A multideck vibrating screen separates the output into commercial fractions (05mm, 510mm, 1020mm, 2040mm). Les matériaux surdimensionnés sont recyclés.

Champ d'application: Suitable for medium to largescale commercial quarries, production de fondations routières, and concrete aggregate plants. Limites: Non conçu pour être mouillé, sticky clay materials (au-dessus de 8% teneur en humidité) or for primary reduction of boulders exceeding 800mm in size without a dedicated feeder breaker.

6. SCÉNARIOS D'APPLICATION

Production de couches de base pour autoroutes | Défi: A contractor in Texas needed 200,000 tons of crushed limestone base (Grade 1) with a strict 100% fracture face requirement and a maximum 10% fines content. Existing impact crushers produced excessive fines (18%), failing specification. | Solution: Implemented the Commercial Stone Crusher Machine with a closedcircuit cone and VSI configuration. The cone crusher provided primary reduction, while the VSI imparted the required fractured faces. | Résultats: Réalisé 100% fracture face count. Fines content reduced to 8.5%. Taux de production de 280 TPH was maintained for 14 mois. Wear cost was $0.31/ton, 22% below budget.

River Gravel Processing for Concrete | Défi: A readymix concrete producer in Vietnam was using a jaw crusher followed by a cone crusher for river gravel. The resulting aggregate had a high flakiness index (28%), causing poor workability in concrete mixes and higher cement demand. | Solution: Replaced the secondary cone with the CSC350's impact crusher with tungsten carbide blow bars. The impact action shattered the flat particles. | Résultats: L'indice de desquamation est tombé à 11%. Concrete slump improved by 40mm. Consommation de ciment réduite de 12 kg/m³. The blow bars lasted 1,200 hours on the abrasive river gravel, un 300% improvement over standard manganese steel.

Agrandissement de la carrière de roche dure | Défi: A granite quarry in Norway needed to increase production from 150 TPH à 300 TPH without expanding the existing primary crusher footprint. The existing jaw crusher was at capacity. | Solution: Installed the CSC350 as a secondary/tertiary circuit, fed by the existing primary. The system's highcapacity cone crusher handled the increased load. | Résultats: Total plant throughput increased to 310 TPH. The existing primary crusher now operates at 85% charger, extending its service life. Energy consumption per ton dropped from 2.1 kWh to 1.4 kWh.

8. FAQ

Q: Can this machine handle basalt with a compressive strength of 350 MPa?
UN: Oui. The CSC350 is rated for materials up to 400 MPa SCU. Cependant, for basalt above 300 MPa, we recommend the Premium Package with a heavyduty bowl liner and manganese steel chamber. Expect wear life to be approximately 180 hours on the cone liners.

Q: What is the typical installation timeline from delivery to first production?
UN: For a prepared concrete pad, installation and commissioning typically takes 1418 working days with a 4person crew. The Turnkey Package includes our installation team, reducing this to 1012 jours.

Q: How does the automatic overload protection work if a steel bar enters the crusher?
UN: The hydraulic relief system activates within 0.2 secondes. The crusher setting opens to 200mm, allowing the tramp iron to pass. The system then automatically resets to the original closed side setting. This prevents damage to the main frame and eccentric shaft.

Q: What is the annual maintenance cost as a percentage of the purchase price?
UN: Pour un 250 TPH operation processing granite, annual maintenance (pièces d'usure, huile, filtres, travail) is approximately 810% of the purchase price. This is lower than the industry average of 1215% due to the hydrostatic drive and automated lubrication.

Q: Can I integrate this system with my existing primary crusher?
UN: Oui. The CSC350 is designed as a modular system. We provide interface conveyors and a control system that can be synced with your existing PLC. A site survey is required to confirm conveyor heights and electrical compatibility.

Q: What is the lead time for replacement wear parts?
UN: Standard manganese steel liners are stocked and ship within 5 jours ouvrables. Highchrome blow bars and custom bowl liners have a 46 week lead time. We recommend maintaining a spare set of liners for the cone and VSI crushers.

Q: Does the equipment comply with CE or ASME standards?
UN: Oui. The CSC350 is manufactured to CE (européen) and ASME (American) normes. The electrical panels are UL listed. We can provide certification documentation for local regulatory approval.
