1. OUVERTURE ENTRAÎNÉE PAR POINT DE DOULEUR

Gérez-vous une opération de granulats à moyenne ou grande échelle et faites-vous face à des goulots d'étranglement constants dans votre circuit de concassage primaire ?? The challenges of sourcing and operating a 250300tph stone crushing plant are significant. Inconsistent feed size reduces your effective throughput, causing you to miss daily production targets. Frequent liner changes and mechanical wear on crushers lead to unplanned downtime, coûtant des milliers de dollars par heure en perte de revenus et en main d'œuvre inutilisée. En outre, integrating disparate equipment from multiple suppliers often results in compatibility issues, creating operational complexity and higher maintenance costs. Are these issues impacting your bottom line? Comment pouvez-vous obtenir un, highvolume output while controlling operational expenses? The solution lies in a correctly specified, fully integrated plant designed for this critical capacity range.

2. APERÇU DU PRODUIT

Ce produit est un complet, stationnaire 250300 Usine de concassage de pierre TPH designed as a turnkey solution for highvolume aggregate production. It is engineered for primary contractors and quarry owners requiring consistent output for road base, granulat de béton, ou ballast ferroviaire.

Flux de travail opérationnel:
1. Concassage primaire: Matière première de grande taille (jusqu'à 750 mm) est réduit par un concasseur à mâchoires robuste ou un impacteur primaire.
2. Secondaire & Concassage Tertiaire: Material is conveyed to secondary cone crushers and tertiary impact crushers for further size reduction and shaping.
3. Dépistage & Classification: Multipledeck vibrating screens separate crushed stone into precise specification fractions.
4. Manutention des matériaux: A network of belt conveyors with adjustable speeds facilitates efficient material transfer between stages.
5. Stockage: Finished products are conveyed to designated stockpiles via radial stackers or fixed conveyors.

Champ d'application & Limites:
Portée: Idéal pour le hard rock (granit, basalte) and mediumhard rock (calcaire) applications in quarrying, exploitation minière, et grands projets d'infrastructures.
Limites: Ne convient pas aux collants, highclay content materials without prescreening/scalping. Plant layout requires significant space for equipment placement and material stockpiling.

6. SCÉNARIOS D'APPLICATION

Projet d'agrandissement de la carrière de granit

Défi: A regional quarry needed to increase output from 180tph to over 280tph to fulfill a major highway contract but had limited space for plant expansion within the existing pit perimeter.
Solution: Mise en œuvre d'un pacte, threestage crushing plant featuring a large jaw crusher, a single powerful multicylinder cone crusher for secondary/tertiary duty, and tightly integrated screening towers.
Résultats: Achieved sustained output of 290tph within the existing footprint. The simplified flow reduced conveyor lengths, lowering overall power draw by an estimated ₹9 lakhs annually.

Traitement du calcaire pour l’alimentation des cimenteries

Défi: A cement producer’s captive mine required a reliable supply of correctly sized limestone feedstock (025mm &2550mm). Their old twostage plant produced excessive fines (<5mm) causing kiln feed inefficiency.
Solution: A tailored crushing circuit emphasizing precise reduction ratios with cone crushers equipped with chamber automation systems was installed as the new primary crushing station near the mine face.
Résultats: Production of target fractions increased by over ₹22%, significantly reducing waste fines generation while meeting the full ₹280tph feed requirement consistently.

Recyclage de projets d’infrastructures urbaines

Défi:A contractor working on an urban ring road needed to process demolished concrete onsite into RCA but faced strict noise,poussière,and space constraints prohibiting traditional mobile units which couldn't meet volume demands either .
Solution:A semiportable,totally enclosed stationary plant rated at ₹260tph was deployed.It featured extensive sounddampening enclosures,a comprehensive waterbased dust suppression system,and was fed directly by excavators .
