Présentation du produit: Concasseur à mâchoires primaire de grande capacité

Ce produit est un produit robuste, singletoggle jaw crusher engineered for the primary crushing stage in mining, carrière, et recyclage de construction à grande échelle. Its design focuses on reducing runofmine or quarryrun material to a consistent, manageable size for downstream processing.

Flux de travail opérationnel:
1. Consommation alimentaire: Matière première de grande taille (jusqu'à 1,5 m de longueur de bord) est dirigé vers les profondeurs, chambre de concassage sans étouffement provenant d'un alimentateur vibrant pour grizzlis.
2. Concassage compressif: The robust, oscillating jaw plate applies intense compressive force against the fixed jaw, fracturation de la roche le long de ses lignes de clivage naturelles.
3. Réglage de décharge: The crushed material exits at the bottom aperture, with particle size precisely determined by the hydraulically adjustable closedside setting (CSS).
4. Éjection de matière: The aggressive stroke pattern and chamber design promote positive discharge, preventing material packing and promoting throughput.

Champ d'application & Limites:
Portée: Ideal for hard abrasive rock (granit, basalte), pierre mi-dure (calcaire), et débris de démolition en béton armé. Serves as the first stage in multistage crushing circuits.
Limites: Ne convient pas aux sols mouillés, sticky materials without prescreening; not designed for final product shaping or ultrafine grinding.

Scénarios d'application

Exploitation d'une carrière de granit

Défi: A large granite quarry faced excessive downtime due to tramp metal events from drill bits and hammer tips, causing catastrophic damage to the crusher's toggle mechanism.
Solution: Implementation of our primary jaw crusher with a full hydraulic toggle system.
Résultats: Three tramp metal events in the first year were cleared automatically within minutes via remote operation. Cela a empêché une estimation 36 hours of downtime per event previously required for cutting torch extraction and repair.

Urban Construction Recycling Plant

Défi: Processing demolished reinforced concrete created inconsistent product gradation due to rebar mesh causing "stringering," leading to poor performance in secondary impact crushers.
Solution: Installation of our unit with an aggressive stroke profile and composite jaw plates configured for slab breaking.
Résultats: Product gradation consistency improved by over 60%, measured by standard deviation of topsize output. Secondary crusher throughput increased by 18% due to more uniform feed.

Foire aux questions

T1: Is this primary jaw crusher compatible with my existing secondary cone crusher circuit?
Oui. The hydraulically adjustable CSS allows precise control of your primary crushed product size (250mm typique), which is critical as feed optimization for most secondary cone crushers improves their efficiency by up to 15%.

T2: Quel est l'impact opérationnel attendu lors de l'installation?
Pour un nouveau site, installation follows standard civil works timelines (~46 weeks). For retrofit into an existing line using our modular frame design requires planned downtime typically between 710 days including foundation modifications if necessary.

T3: How does the composite jaw plate affect longterm operating costs?
While initial purchase price is higher than standard manganese plates field data shows they last 4060% longer This translates directly into fewer changeouts reduced labor costs less inventory held on site resulting in lower total cost over any given production period
