1. OUVERTURE ENTRAÎNÉE PAR POINT DE DOULEUR

Gérer une exploitation de sable et de gravier signifie faire face à des défis persistants qui érodent directement la rentabilité.. Êtes-vous confronté:
Temps d'arrêt élevés dus à des blocages: Bridging and ratholing in hoppers and screening decks halts production, costing hours of lost throughput per incident.
Classification des matériaux inefficace: Inconsistent screen performance leads to product contamination, resulting in offspec material that requires reprocessing or sells at a discount.
Usure excessive & Coûts d'entretien: Abrasive sand and gravel rapidly degrade standard components, entraînant des changements fréquents de doublure, conveyor belt damage, and unscheduled maintenance stops.
Intensité énergétique: Inefficient material handling and processing systems consume excessive power per ton of final product, a direct and growing operational cost.
Espace & Contraintes d'autorisation: Statique, fixedplant designs limit operational flexibility and make permitting for new sites or expansions increasingly difficult.

La question centrale pour les directeurs d'usine est: how can you increase reliable throughput while controlling the operational costs of wear, énergie, and downtime?

2. APERÇU DU PRODUIT: MOBILE TRACKMOUNTED SCREENING PLANT

This equipment is a selfcontained, trackmounted mobile screening plant designed for primary screening, scalper, and stockpiling in sand and gravel extraction. It is engineered for quarry face advancement, processing natural sand and gravel deposits, and handling crushed stone.

Flux de travail opérationnel:
1. Direct Feed: Excavator or wheel loader feeds runofquarry material directly onto the integrated feed hopper.
2. Présélection & Suppression des amendes: A heavyduty vibrating grid or grizzly section removes natural fines prior to the main screen, améliorer l'efficacité.
3. Primary Classification: Material is conveyed to a highcapacity, tamis vibrant à plusieurs étages (typiquement 2 ou 3 ponts) for precise sizing into specified aggregates (par ex., surdimensionné, 2” rock, 1” rock, sable).
4. Stockage & Transport: Sized fractions are discharged onto radial conveyors or stockpile conveyors for direct truck loading or ground stockpiling.
5. Déménagement & Installation: The unit moves under its own trackdriven power between faces or sites without need for disassembly or external haulage.

Champ d'application & Limites:
Portée: Ideal for virgin aggregate deposits, opérations minières dans le lit de la rivière, and site development projects requiring onsite material processing. Excellent for contractors needing to establish temporary processing points.
Limites: Not designed as a standalone solution for hard rock primary crushing or as a finished sand washing system. Maximum feed size is typically limited by the dimensions of the integrated grizzly section.
