1. OUVERTURE ENTRAÎNÉE PAR POINT DE DOULEUR

Gérez-vous une opération de production de granulats à moyenne ou grande échelle et faites-vous face à des goulots d'étranglement persistants qui érodent la rentabilité ?? Pour les directeurs d’usine et les entrepreneurs en ingénierie, un 250300 tph stone crushing plant is a critical capital asset, yet standard configurations often introduce costly vulnerabilities.

Risque de non-conformité réglementaire: Sourcing components from multiple vendors creates a compliance gray area. A single noncompliant electrical component or material can halt shipments to regulated markets, resulting in project delays and contractual penalties.
Débit incohérent & Hidden Downtime: Promised 300tph capacity often drops under realworld conditions due to feeder mismatches, crusher choke points, ou de dépistage des inefficacités. Ce 1015% deficit translates to thousands of tons of lost production monthly.
Unscheduled Maintenance Spikes: Plants built with offtheshelf, nonintegrated components suffer from uneven wear and premature failures. Unplanned downtime for crusher liner changes or conveyor belt repairs directly impacts your costperton metric.
Intensité énergétique & Coûts opérationnels: Inefficient drive systems and poorly optimized crushing chambers consume excess power. For a plant running 16 hours/day, even a 5% overconsumption leads to a significant annual energy cost burden.

La question centrale est: how do you achieve guaranteed, compliant throughput without sacrificing operational flexibility or facing unpredictable lifecycle costs?

2. APERÇU DU PRODUIT

This product describes a fully integrated, Rohs Compliant 250300tph Stone Crushing Plant. It is a stationary or semimobile crushing and screening circuit engineered as a unified system from primary feed to final product stockpiling.

Flux de travail opérationnel:
1. Réduction primaire: Matériau brut de carrière (≤750mm) is fed via a vibrating grizzly feeder to a primary jaw crusher, atteindre la première étape de réduction de taille.
2. Concassage intermédiaire & Dépistage: Le matériau broyé est transporté vers un concasseur à cône secondaire. The output is then screened; oversize material is recirculated back to the secondary crusher (circuit fermé), tandis que le matériau correctement dimensionné avance.
3. Façonnage tertiaire & Dimensionnement final: For highquality chip and sand production, un impact d'arbre vertical tertiaire (TOUT LE MONDE) crusher may be employed for shaping. Final screening decks separate output into precise product fractions (par ex., 05mm, 510mm, 1020mm).

Champ d'application: Idéal pour produire des agrégats pour la base des routes, béton prêt à l'emploi, asphalte, and railway ballast from limestone, granit, basalte, et gravier de rivière.
Limites: Not designed for very abrasive metallic ores or sticky, highclay materials without specific configuration modifications.

8.FAQ

Q:What defines 'ROHS Compliant' fora complete crushing plant?
UN:The Restriction of Hazardous Substances(RoHS) directive restricts specific materialsin electrical/electronic equipment.A fully compliant plant ensures every purchased component—from motorsand PLCsto wiring,cables,and control panels—is certified freeof restricted substanceslike leador mercury.This providesa single,documented chainof custodyfor your entire production line's output.

Q:Canyou integrate an existingcrusherof oursinto this newplant design?
A.We can conductan engineering assessment.Often,the limiting factoris ensuringthe existing unit's electrical componentsandsupplied documentationmeetROHS standards.If it does not,the integration would compromisethe fullplant certification.We typically recommendour matchedcomponentset tomaintain guaranteed performanceand compliance integrity.

Q:Whatisthe expected increasein our operational expenditure(OPEX)?
A.The initial investmentis offsetby measurable OPEX reductions.Field reports indicateenergy savings of15%,lower spare partsinventory costs,and reduced downtime.The central lubrication systemalso lowers labor hoursfor routine maintenance.A detailedTotal Costof Ownership(Coût total de possession) modelwill be provided during proposal development.

Q:What happens ifa component failsand needs replacement?Does it void the compliance?
A.No.All recommended spare partsare sourcedfrom the same certified supply chain.Any replacement partwe supply will maintainthe plant's overall compliance status.This is acore benefitofa singlesource solution versusamultivendor assembly.

Q:What site preparationis requiredbefore delivery?
A.We provide comprehensive foundation drawingsanda site preparation checklist.Typical requirementsinclude leveled compacted ground,poured concrete foundationsforspecific modules,and provisionofthe main power supply connection pointat the specified rating.Civil works can oftenbe reducedby25% comparedto traditional plantsdue tour modular design philosophy
