In the modern construction materials industry, the efficient handling of bulk stone and aggregate materials is essential for maintaining production quality and output. Whether preparing crushed stone for concrete, road bases, or general construction applications, proper screening plays a crucial role in ensuring material consistency and equipment protection. The BTS Bar Vibrating Screen is designed precisely for such demanding tasks, offering a robust, energy-efficient solution for the screening and grading of block and granular materials, especially in construction aggregate processing.
Purpose-Built for Stone and Aggregate Screening
The BTS Bar Screen is a type of vibrating screen developed specifically for use in pre-screening or primary classification of building stone and other coarse materials. It excels in separating unwanted fines or sticky material before it reaches downstream equipment, helping to protect crushers from overloading and improving the overall efficiency of the crushing and grading process.
One of the standout qualities of the BTS Bar Vibrating Screen is its adaptability to various material sizes, including both large blocks and smaller granules—a necessity in construction aggregate applications where material types and feed conditions can vary widely.
Key Features and Technical Advantages
1. Self-Cleaning Bar Design
One of the major challenges in handling stone materials—especially when moisture or fine dust is present—is material buildup on the screening surface. The BTS Bar Screen incorporates a self-cleaning bar design, which effectively prevents material from sticking or clogging between the screen bars. This not only ensures consistent screening performance but also reduces maintenance downtime and cleaning labor.
2. New-Generation Exciter for Stronger Vibration
At the heart of the BTS screen is a newly developed vibration exciter, engineered to deliver stronger and more stable excitation forces. This powerful vibration improves the screening efficiency, ensuring effective stratification and separation of materials, even under heavy loads. It is especially useful when handling rough, heavy stones and inconsistent feed sizes.
3. High Energy Efficiency
Despite its high-output capacity and strong vibration, the BTS Bar Screen is built for energy savings. Its efficient excitation mechanism and low-resistance material flow contribute to significantly reduced energy consumption—an essential feature for businesses aiming to reduce operational costs and carbon footprint.
4. Ideal for Block and Granular Material Classification
The BTS screen is optimized for both large block stones and medium to small granular materials. Its bar-style design allows oversized materials to pass without obstruction while enabling finer particles to drop through for further processing. This makes it suitable for multi-stage crushing systems, where precise separation at the early stage can drastically improve performance downstream.
5. Rugged Construction for Harsh Environments
Built for durability, the BTS Bar Screen is made from wear-resistant, high-strength materials to handle the abrasion and impact of rough stone particles. Its simple mechanical structure and reinforced frame ensure long service life even under continuous, high-capacity operations typical in quarries and construction material plants.
Applications in Construction Aggregate Processing
The BTS Bar Vibrating Screen is especially suited for:
- Pre-screening of large stone blocks before jaw or cone crushers
- Removal of sticky fines and soil from aggregate material
- Grading of crushed construction rock, limestone, granite, and gravel
- Front-end screening in sand and gravel production lines
- Scalping in road base material preparation
By eliminating undersized or sticky particles early in the process, the BTS screen significantly improves the efficiency and life span of downstream equipment, including crushers, conveyors, and secondary screens.
