Mot clé ciblé: Mobile TrackMounted Screening Plant

1. Addressing Your Core Operational Challenges in Material Sizing

Are inconsistent feed materials and fluctuating project demands causing bottlenecks in your aggregate production? When your static screening setup cannot follow the face, you incur significant costs in material rehandling, double handling, and excessive loader hours. Plant managers and contractors face three persistent challenges:

High Mobilization Costs & Temps d'arrêt: Relocating between sites or adjusting to new pit faces with fixed plants can take days, directly impacting project timelines and labor costs.
Flux de matériaux inefficace: Processing oversize material at the primary crusher when it could have been screened out first wastes fuel, augmente l'usure, and reduces total system throughput.
Lost Revenue from Specification NonCompliance: Inability to quickly adjust screen media or plant configuration to meet changing product specs leads to stockpiles of offspec material, diminishing its market value.

What if your screening operation could be repositioned in hours, pas des jours? How would direct feeding from the face impact your cost per ton? This content outlines how a modern mobile trackmounted screening plant addresses these exact pain points.

2. Présentation du produit: HighCapacity Mobile TrackMounted Screening Plant

A mobile trackmounted screening plant is a selfpropelled, dieselhydraulic machine designed for the primary separation and sizing of bulk materials such as aggregates, topsoil, charbon, et déchets de démolition. Its core function is to improve overall system efficiency by removing fines or separating fractions before crushing, or producing finished spec products directly from runofmine (ROM) matériel.

Flux de travail opérationnel:
1. Positionnement: The plant uses its tracked undercarriage to position itself directly at the feed source (face, stockpile, or upstream crusher), minimizing truck or loader cycle time.
2. Alimentation & Dépistage: Material is fed via excavator or wheel loader onto a vibrating grid or conveyor, which transfers it to the primary screenbox. The aggressive screen action separates particles by size.
3. Stockage: Correctly sized material discharges via radial conveyors into distinct stockpiles. Oversize material can be directed to a crusher or a waste pile.

Champ d'application & Limites:
This equipment is optimal for quarrying, exploitation minière, construction & recyclage de démolition, et aménagement paysager. It is designed for mediumtohigh volume operations requiring frequent relocation. It is not a replacement for a hightonnage fixed plant in a singlelocation, 20year reserve scenario and has inherent size limitations on feed material compared to a primary crusher.

6. Scénarios d'application

Projet d'agrandissement de la carrière de granulats

Défi: A regional quarry won a contract requiring three distinct aggregate products from a new pit located 1km from their fixed primary plant. Hauling all ROM material was costprohibitive.
Solution: Deployment of one mobile trackmounted screening plant at the new pit face to scalp oversize rock and produce two finished sand products onsite.
Résultats: Reduced haul truck requirements by 40%, lowered cost per ton of finished product at the new pit by 22%, and allowed the fixed plant to focus on highvolume base material production.
