CVB1845 Fixed Screen

 

The Metso inclined CVB1845 screen delivers outstanding performance, versatility, and proven durability for demanding screening applications. Featuring a full 1.8 m × 4.5 m screening surface (8.1 m² total area), it maximizes throughput while maintaining a compact footprint. Built for consistent material flow and precise separation, this robust screen thrives in both stationary and mobile plants.
Designed for quarries, gravel pits, mines, crushing contractors, and portable operations, the Compact CVB1845 ensures reliable performance under the toughest conditions.

Available in three versatile modular configurations, each variant adapts effortlessly to diverse feed materials and production goals – from heavy-duty primary scalping to high-precision finishing.

  • CVB1845 3M:
    A modular 3-deck screen for secondary/tertiary screening, focusing on finer material separation after initial crushing stages.
  • CVB1845 3PM:
    A primary 3-deck module for primary screening, with enhanced feed handling, handling coarser feed directly from crushers with higher capacity demands.
  • CVB1845 4M:
    A modular 4-deck screen for secondary/tertiary screening, like the 3M but with an extra deck for advanced fine classification offering more precise multi-stage separation of finer fractions.

All models in the Compact CVB Series™ are inclined, circular-motion vibrating screens designed for efficient screening in aggregates, quarries, mining, and portable applications. Optimised for high portability and rapid setup, they support adjustable stroke, RPM, and screening media (tensioned or modular snap-on panels) for versatile performance.

Product Information

CVB1845 3M (Secondary/Tertiary)
Number of Decks 3
Application Focus Secondary/tertiary (finer fractions, post-crushing)
Vibrator Type 2 × MV2 (smaller, balanced for efficiency in finer screening)
Screening Area 8.1 m² (total)
Capacity (Indicative Max Feed, t/h) 360 (based on standard CVB1845-3; lower due to secondary focus)
Weight (kg) ~4,500 (compact for portability)
Modular Integration Deck module for easy addition to fixed/mobile plants; weld-free side walls for fatigue resistance
Motion & Efficiency Circular motion at 18° incline; even material travel for accurate fine separation
Wear Protection Standard rubber liners on feed box/discharge; optional cross-member liners
Typical Use Case Intermediate/fine product classification; wet/dry rinsing optional
CVB1845 3M (Primary)
Number of Decks 3
Application Focus Primary (coarse feed, pre-crushing separation)
Vibrator Type 2 × MV2 (optimised for higher throughput in coarse material)
Screening Area 8.1 m² (total)
Capacity (Indicative Max Feed, t/h) 500 (higher for primary scalping and oversize removal)
Weight (kg) ~5,000–5,500 (slightly heavier for robust primary duty)
Modular Integration Primary deck module with deeper feed box for direct crusher interface; enhanced wear liners for abrasive coarse feed
Motion & Efficiency Circular motion at 18° incline; higher energy for rapid coarse stratification and higher G-forces
Wear Protection Enhanced liners and bolted (not glued) options for faster replacement in high-abrasion primary environments
Typical Use Case Scalping large oversize; recirculation to crushers; higher tonnage handling
CVB1845 4M (Secondary/Tertiary)
Number of Decks 4
Application Focus Secondary/tertiary (enhanced fine separation with additional deck)
Vibrator Type 2 × MV2 (balanced for multi-deck efficiency in finer screening)
Screening Area 10.8 m² (total)
Capacity (Indicative Max Feed, t/h) 400 (moderate increase over 3M for finer multi-stage processing)
Weight (kg) ~~5,100 (increased for extra deck)
Modular Integration Deck module like 3M, but with additional deck for scalable fine classification in modular systems
Motion & Efficiency Circular motion at 18° incline; optimized for layered fine separation across more decks
Wear Protection Similar to 3M, with optional bolted liners for extended multi-deck use
Typical Use Case Advanced fine product classification and dewatering; ideal for high-precision secondary stageshandling
