In a wide range of heavy industries, from metallurgy and coal processing to construction materials, chemical engineering, and hydropower, efficient material handling and classification is essential for maintaining productivity and ensuring consistent output quality. The BTS Bar Screen—also known as a Bar Vibrating Screen—is a highly durable and efficient machine designed for screening, grading, and washing a variety of bulk materials.

Thanks to its rugged construction and advanced vibratory design, the BTS Bar Screen plays a critical role in pre-screening operations, especially in applications involving coarse, sticky, abrasive, or irregularly sized materials. Whether separating iron ore, removing impurities from limestone, or classifying cooling blast furnace slag and coke, this bar screen delivers reliable performance in even the harshest environments.

Wide-Ranging Applications

The BTS Bar Vibrating Screen is engineered for versatility and durability, making it ideal for the following industries and materials:

• Metallurgy: Iron ore, limestone, fluorite, blast furnace slag, coke
• Coal and Coke: Raw coal, washed coal, coke preparation
• Chemical Processing: Bulk solids separation and screening
• Building Materials: Stone aggregates, sand, limestone pre-screening
• Hydropower Projects: Screening of construction stone and gravel
• Waste Treatment: Abrasive and construction waste screening
• Quarrying and Mining: Pre-screening and grading of extracted materials

This broad applicability makes the BTS Bar Screen a go-to solution for companies seeking efficient material preparation before crushing, sorting, or washing processes.

Working Principle of the BTS Bar Screen

The core function of the BTS Bar Screen is based on a vibration-driven screening mechanism. When in operation, the screen is activated by a powerful vibration exciter, which generates a longitudinal (forward-backward) vibratory force. This force is transmitted through the screen box to the screening surface—where material separation begins.

As the vibration exciter drives the screen box, the screen surface moves forward and backward in a longitudinal motion. Under this repeated motion, materials sitting on the screen surface are thrown forward in a parabolic path. During each cycle:

• Larger particles are conveyed forward.
• Smaller particles, those smaller than the gaps between the bars, fall through the screen into the lower layer or discharge zone.

This continuous parabolic movement ensures an efficient separation process, where materials are consistently agitated, stratified, and sorted based on size.

The key advantage of this mechanism is that it prevents material clogging, especially with damp, sticky, or irregular materials, and ensures a high screening efficiency without requiring complex mechanical components.

Key Benefits of the BTS Bar Screen

• Efficient Material Separation: Ideal for coarse pre-screening, the bar screen separates fines from oversize particles, improving downstream processing.
• Robust and Low-Maintenance: The screen is built for durability with minimal moving parts, making it easy to maintain and ideal for rugged environments.
• Self-Cleaning Capability: The spacing and movement of the bars reduce material build-up, especially with sticky or moist materials.
• Versatile Design: Suitable for a variety of material types—ranging from ore and slag to coal and construction debris.
• Customizable Configurations: Available in multiple sizes and configurations to meet different operational needs and feed capacities.
