Fiche technique de l'usine d'assemblage d'extraction de gravier de sable
1. OUVERTURE ENTRAÎNÉE PAR POINT DE DOULEUR
Managing a sand and gravel mining operation means contending with persistent bottlenecks that directly erode profitability. Êtes-vous confronté à ces défis communs?
Flux incohérent & Processing Bottlenecks: Variable feedstock from the pit leads to surges and starvation in your plant, causing constant manual adjustment, débit réduit, and higher wear on crushers and screens.
Temps d'arrêt excessif pour la maintenance: Traditionnel, hardwired plant designs with multiple conveyors and transfer points require frequent liner changes, réparations de courroie, et remplacement des roulements, leading to hundreds of unplanned downtime hours annually.
Travail élevé & Intensité énergétique: Operating multiple standalone units—excavators, mangeoires, concasseurs, screens—requires significant fuel and operator hours per ton of final product.
Difficulté à répondre aux spécifications & Contamination du produit: Inefficient separation and screening processes result in offspec material or crosscontamination between product stockpiles, leading to rejected loads and revenue loss.
Limited Site Mobility & High Redeployment Costs: Fixed or semimobile plants are capitalintensive to relocate, locking you into a single deposit and preventing pursuit of new market opportunities.
What if your primary processing could be consolidated into a single, intelligent unit that addresses these issues directly? The solution lies in reevaluating your plant’s core assembly.
2. APERÇU DU PRODUIT: Modular Sand & Gravel Mining Assembly Plant
The Modular Sand & Gravel Mining Assembly Plant is an integrated processing system designed to replace traditional fixedplant setups. It combines primary crushing, dépistage, material washing (facultatif), and conveying into a single, trailermounted footprint. This configuration is engineered for rapid deployment and highvolume production in sand and gravel extraction.
Flux de travail opérationnel:
1. Integrated Feeding & Concassage primaire: Runofpit material is fed directly into the hopper module, which regulates flow to the integrated jaw or impact crusher.
2. Onboard Primary Screening: Crushed material is immediately conveyed to an integrated vibrating screen deck for primary size separation.
3. Product Routing & Stockage: Oversize material may be recirculated or diverted, while onspec sand and aggregate fractions are conveyed via onboard stacking conveyors to designated stockpiles. An optional integrated screw washer or cyclones can be incorporated for sand classification.
Champ d'application:
Ideal for virgin aggregate deposits requiring primary reduction.
Suited for mediumtohigh volume operations (see specifications).
Effective for producing road base, granulat de béton, and washed mason sand.
Limites:
Not designed as a tertiary finishing plant for precision asphalt chips.
Maximum feed size is constrained by the model’s integrated crusher aperture.
Requires stable ground conditions for setup without extensive civil works.
3. CARACTÉRISTIQUES PRINCIPALES
Unified Chassis Design | Base technique: Structural integrity analysis with centralized load distribution | Avantage opérationnel: Enables relocation within 2448 hours using standard heavy haul equipment | Impact sur le retour sur investissement: Reduces site mobilization/demobilization costs by up to 60% compared to fixed plant construction.
Système de contrôle d'alimentation intelligent | Base technique: Variateur de fréquence (VFD) on feeder coupled with crusher amp monitoring | Avantage opérationnel: Automatically regulates feed rate to maintain optimal crusher cavity fill, preventing overloads and chokefed stalls | Impact sur le retour sur investissement: Increases crusher throughput by 1520% while reducing liner wear costs.
Intégration de la suppression de la poussière | Base technique: Pressurized water spray bars at all transfer points with particle size analysis for flow control | Avantage opérationnel: Maintains regulatory compliance and improves site visibility/safety without external systems | Impact sur le retour sur investissement: Eliminates standalone dust control capital expenditure and reduces water consumption by 30% par rapport aux systèmes manuels.
Hydraulic Set Adjustment & Clairière | Base technique: Centralized hydraulic power unit for crusher gap adjustment and patented clearing cylinder system | Avantage opérationnel: Allows operators to adjust product gradation or clear blockages from ground level in minutes | Impact sur le retour sur investissement: Réduit de plus de temps les temps d'arrêt pour les ajustements de routine 90% versus mechanical shim systems.
Prewired Control & Instrumentation Package | Base technique: PLCbased control panel with motor management diagnostics and remote monitoring capability | Avantage opérationnel: Provides singlepoint startup/shutdown sequence protection and identifies potential faults before failure | Impact sur le retour sur investissement: Lowers electrical installation costs by ~40% and enables predictive maintenance planning.
