1. OUVERTURE ENTRAÎNÉE PAR POINT DE DOULEUR

Are escalating operational costs and unpredictable downtime eroding your sand and gravel profit margins? Common industry challenges directly impact your bottom line:
Inefficient Material Classification: Inconsistent screen performance leads to offspec product, costly reprocessing, and lost revenue from premium material fractions.
High Maintenance & Temps d'arrêt: Frequent bearing failures, screen cloth changes, and structural wear on vibrating equipment result in excessive labor costs and halted production.
Intensité énergétique: Older screening technology consumes disproportionate power for the processed tonnage, making energy a volatile and significant cost factor.
Aveuglant & Pegging: Moisture and nearsize particles clog screen apertures, drastically reducing effective screening area and throughput until manual intervention.
Space & Footprint Constraints: Inflexible plant layouts limit capacity expansion and make it difficult to integrate new processing stages.

How do you increase throughput of inspec material while controlling maintenance costs and energy consumption? The efficiency of your entire washing and classification circuit hinges on the performance of a single component: your primary screening solution.

2. APERÇU DU PRODUIT

Le HighCapacity Horizontal Vibrating Screen is engineered as the primary classification workhorse for hightonnage sand, gravier, et usines de traitement des granulats. It separates feed material into precise size fractions—such as oversize rock, intermediate gravel, and sand—for downstream crushing, lavage, or direct stockpiling.

Flux de travail opérationnel:
1. Alimentation & Distribution: Runofmine or crushed material is evenly distributed across the full width of the screen box via a feed box or conveyor.
2. Stratification & Séparation: A highGforce, linear vibrating motion stratifies material, lifting smaller particles to the top layer for contact with the screen media while conveying larger particles across the deck surface.
3. Size Fraction Discharge: Correctly sized particles pass through the screen apertures (unders), while oversized material travels along the deck to discharge at the end of each deck level into designated chutes or conveyors.

Champ d'application: Ideal for primary sizing (scalper) of pitrun material, secondary screening behind crushers, and final product sizing for concrete sand or road gravel. Not recommended for dewatering applications or handling highly adhesive clays without specialized modifications.

6. SCÉNARIOS D'APPLICATION

[Large Aggregate Producer – Midwest USA] Défi: An aging screening plant could not meet demand for state DOT concrete sand specification (<0.25” fines), resulting in excessive recirculating load crushing circuit inefficiency.Solution: Installation of a new horizontal vibrating screen fitted with polyurethane panels sized precisely for the critical separation.Résultats: Screening efficiency increased from an estimated ~82% to a measured >94%. Production of inspec concrete sand rose by over ~30%, allowing dedicated stockpiling without blending.

[Sable & Gravel Pit – Mountain Region] Défi: High moisture content in spring months caused severe blinding of wire mesh screens on washed gravel lines requiring hourly shutdowns for manual cleaning.Solution: Retrofitting existing screens with tensioned polyurethane panel systems designed specifically for wet/sticky applications.Résultats: Blinding incidents were virtually eliminated even during peak moisture periods allowing continuous operation results showed an average increase of ~17 weekly operating hours during problematic seasons.
