1. OUVERTURE ENTRAÎNÉE PAR POINT DE DOULEUR

Are you managing a midtolarge scale aggregate operation and facing persistent bottlenecks in output and compliance? Pour les directeurs d’usine et les entrepreneurs en ingénierie, un 250300 tph crushing plant is a critical production asset, yet standard configurations often introduce significant operational friction. Les défis courants incluent:
Temps d'arrêt imprévus: Component failures in nonintegrated systems can halt your entire line for 2448 heures, costing thousands in lost production and labor.
Réglementaire & Tender Disqualification: An increasing number of municipal and international construction projects now mandate RoHS (Restriction des substances dangereuses) compliance for equipment. Noncompliant plants risk being excluded from lucrative contracts.
Débit incohérent: Fluctuations in feed material or suboptimal crushing chamber flow lead to an average output below the 280 cible tph, failing to meet project schedules.
High Lifetime Operating Costs: Frequent replacement of nondurable wear parts and energyinefficient drives silently erode profit margins over a 5year period.
Complexité opérationnelle: Plants requiring constant manual adjustment and monitoring divert skilled personnel from highervalue maintenance and optimization tasks.

La question centrale est: comment pouvez-vous obtenir un, highvolume production while futureproofing your investment against evolving environmental regulations? La solution réside dans un objectif conçu RoHS Compliant 250300tph Stone Crushing Plant.

2. APERÇU DU PRODUIT

This product is a stationary or semistationary aggregate production plant engineered for consistent output within the 250 à 300 tonnesperhour range. It is designed from the ground up to comply with RoHS Directive 2011/65/EU, ensuring the controlled use of lead, mercure, cadmium, chrome hexavalent, PBB, and PBDE in its electrical components, revêtements, and manufactured assemblies.

Flux de travail opérationnel:
1. Concassage primaire: Matière première de grande taille (≤750mm) is reduced by a robust jaw crusher or gyratory crusher.
2. Secondaire & Concassage Tertiaire: Material is conveyed to cone crushers for further size reduction and shaping to meet specific aggregate gradations.
3. Dépistage & Tri: Vibrating screens separate crushed material into specified product sizes; les matériaux surdimensionnés sont recyclés.
4. Manutention des matériaux: A network of conveyors with centralized control ensures efficient transfer between stages.
5. Suppression de la poussière: Les systèmes de pulvérisation intégrés contrôlent les émissions de particules aux points de transfert.

Champ d'application: Idéal pour produire des agrégats pour la base des routes, béton prêt à l'emploi, asphalte, et ballast ferroviaire. Convient au granit, calcaire, basalte, et gravier de rivière.

Limites: Not designed for abrasive metal ores or sticky, highclay content materials without specific feeder and crusher configuration modifications.
