1. OUVERTURE ENTRAÎNÉE PAR POINT DE DOULEUR

Are you managing sand and gravel extraction with equipment that struggles to keep pace? Operational bottlenecks in material processing directly impact your bottom line through lost production, excessive maintenance, and inconsistent product quality. Les défis courants incluent:

Temps d'arrêt élevés dus à l'usure: Constant abrasion from silica sand and aggregate rapidly degrades standard components, conduisant à de fréquents, unplanned stops for liner changes or crusher maintenance.
Classification des matériaux inefficace: Inaccurate screening and separation results in offspec product, forcing reprocessing that consumes energy and reduces your marketable yield.
Génération d’amendes excessives: Overcrushing or improper processing creates an excess of fine particulate, diminishing the volume of highvalue coarse aggregate and creating waste management issues.
Inflexible Production Flow: Fixedconfiguration plants cannot easily adapt to varying feed material hardness or shifts in market demand for different aggregate sizes.

Is your operation sacrificing profitability to these persistent issues? La solution ne réside pas seulement dans une machine, but in a precisionengineered system designed for the specific demands of sand gravel mining.

2. APERÇU DU PRODUIT

Le [Nom de votre entreprise] Sable haute capacité & Usine de traitement de gravier is a modular, stationary crushing and screening system engineered for highvolume aggregate production. It is designed for operators requiring consistent output of specification sand, gravier, and coarse aggregate from pitrun material.

Flux de travail opérationnel:
1. Réduction primaire: Pitrun material is fed into a robust primary jaw crusher for initial size reduction.
2. Concassage secondaire & Dépistage: Material is conveyed to a cone crusher for further refinement, then screened to separate coarse aggregate.
3. Traitement tertiaire & Lavage: Remaining material is routed through a vertical shaft impact (TOUT LE MONDE) crusher for optimal sand shaping and fines generation control, with optional integrated log washers or sand screws for cleaning.

Champ d'application & Limites:
Portée: Ideal for medium to largescale quarry operations producing construction aggregates (concrete/ asphalt), industrial silica sand, et matériaux de drainage. Effective on limestone, granit, and river rock deposits.
Limites: Not suitable for highly consolidated igneous rock without upstream blasting. Maximum feed size is determined by primary crusher model. Integrated washing requires a consistent water supply and slurry management plan.

6. SCÉNARIOS D'APPLICATION

Regional Aggregate Supplier & Concrete Producer

Défi: Needed consistent production of both ASTM C33 concrete sand and multiple coarse aggregate sizes from highly variable pitrun gravel. Existing plant produced excessive fines and required constant manual CSS adjustment.
Solution: Implementation of our Model SG450 plant featuring the Adaptive Crushing Chamber Automation and MultiFrequency Screening Deck.
Résultats: Achieved a stabilized yield meeting all spec fractions simultaneously. Fines generation reduced by 22%. Plant output became predictable, allowing accurate batching forecasts for their concrete division.

Sand Mining Operation

Défi: Severe wear costs on tertiary crusher components were eroding margins on specialty silica sand products. Downtime every six weeks for liner replacement was unacceptable.
Solution: Retrofitted existing circuit with our tertiary VSI crusher equipped with PolyCeramic Composite Liners.
