Vibrowest VR Rectangular Vibrating Screens - Technical and Detailed Product Description
The Vibrowest VR series rectangular vibrating screens are high-capacity industrial screening systems developed for the separation, classification, and safety screening of both liquid and dry products. Thanks to their rectangular screen geometry, the VR series offers a significantly larger effective screening area compared to circular systems, providing major advantages in terms of efficiency, stability, and process control, especially in high-throughput applications. This series represents Vibrowest's professional engineering solutions designed for heavy-duty industries and continuous production lines.
VR rectangular vibrating screens are widely used as both classification and safety screens in sectors such as quarries, mining, recycling facilities, raw material preparation, chemical processing, food, agriculture, and plastics industries.
General Design and Mechanical Structure
The key characteristic of the Vibrowest VR series is its rectangular screen body combined with optimized vibration distribution. This design ensures full utilization of the screening surface, increases capacity, and maintains controlled product bed thickness across the entire screen area.
Mechanical structure features include:
• Rectangular screen body providing a large active screening area
• Rigid and robust frame design ensuring stable operation
• Low harmonic vibration for quiet and well-balanced performance
• Heavy-duty bearings and vibration components
• Industrial design suitable for continuous operation
The body and product-contact surfaces can be manufactured in different materials depending on the application:
• AISI 304 stainless steel
• AISI 316 stainless steel
• Painted carbon steel
This flexibility allows the VR series to meet both hygienic requirements in food and pharmaceutical applications and the demanding conditions of heavy industry.
Operating Principle - Combined Conveying and Screening
VR rectangular vibrating screens combine a vibrating channel and screening function within a single machine. Controlled linear vibration generated by vibration motors transports the product across the screen surface while simultaneously performing size separation.
The operating sequence can be summarized as follows:
• The product is evenly fed onto the screen inlet
• Vibration moves the product forward along the screen
• Fine fractions pass through the screen openings and are discharged from the lower outlets
• Oversized particles or foreign objects are conveyed forward and discharged separately
This dual-function design eliminates the need for a separate conveyor, simplifying the process line and reducing equipment complexity.
Screening Layers and Multi-Deck Configuration
One of the most significant advantages of the Vibrowest VR series is its multi-deck screening capability. Depending on process requirements, the screens can be configured as:
• Single-deck
• Double-deck
• Triple-deck
• Up to four-deck configurations
This structure allows multiple fractions to be separated simultaneously within a single machine.
Available screen surface materials include:
• Spring steel wire mesh
• Perforated metal plates
• Polyurethane screen panels
• Rubber screen surfaces
This wide range of options ensures optimal performance for both abrasive materials and products prone to blinding or clogging.
Technical Performance and Operational Advantages
The VR series is optimized for high-capacity and continuously operating production lines. Owing to its rectangular geometry:
• Screening area is used more efficiently than in circular systems
• Product travels along a longer and more controlled screening path
• Screen blinding is minimized
• Stable classification is achieved even at high flow rates
Additionally, under-screen systems equipped with elastomeric anti-blinding balls keep the screen openings continuously clear, reducing downtime and maintenance requirements.
Maintenance and Service Accessibility
The Vibrowest VR series is designed with maintenance efficiency in mind:
• Quick removal and installation of screen frames
• Fast replacement of wear parts
• Low maintenance costs
• Long service life
These features are particularly valuable for facilities operating 24/7, where minimizing downtime is critical.
Certifications and Industry Standards
VR rectangular vibrating screens can be manufactured in compliance with the following standards and certifications upon request:
• ATEX, for potentially explosive environments
• FDA-compliant surfaces and documentation
• IQ / OQ qualification
• GMP procedures
• CE conformity
For food and pharmaceutical applications, hygienic surface finishes and Jacob pipe connections can also be applied.
Application Areas
The Vibrowest VR series is suitable for a wide range of industrial applications:
• Mining and quarries - classification and separation
• Recycling plants - separation of plastic, metal, and glass
• Chemical industry - screening of powders and granules
• Agriculture - grain and dry product classification
• Food and beverage industry - hygienic screening applications
• Plastics industry - safety screening of granules and regranulates
Key Advantages
• High capacity thanks to large screening area
• Conveying and screening combined in a single machine
• Up to four-deck multi-stage screening capability
• Low noise levels and low harmonic vibration
• Wide range of screen surface and material options
• Low maintenance costs and long service life
• Fully customizable, process-oriented design
Vibrowest VR rectangular vibrating screens are advanced screening systems that deliver maximum efficiency, stability, and flexibility in high-throughput and continuous industrial processes. With their large screening area, multi-deck configuration, and durable construction, they can be reliably used in both heavy-duty industrial applications and hygienic environments. The VR series clearly reflects Vibrowest's engineering expertise in separation and classification technologies.
