Welcome to Anping County Boli Hardware Wiremesh Products Factory, a trusted manufacturer since 1998 with an annual export value of US$5-10 million. Our Square Tumbler Sieve Swinging Screening Machine is specially engineered for high-precision sieving of calcium carbonate powder and other fine materials. This machine combines the gentle tumbling action of a circular sifter with the high capacity of a linear screen, delivering unmatched efficiency and particle shape protection. Whether you need to classify 200-mesh limestone powder or de-dust ultrafine GCC, our solution ensures consistent product quality and minimal downtime.
Key Features & Benefits
- Advanced Tumbling Action: The square tumbler mimics the natural sifting motion of human hands, gently moving material across the screen surface. This prevents particle degradation and maintains the original shape of calcium carbonate crystals.
- High Capacity Throughput: With a large screening area and multi-layer design, our machine can handle up to 20 tons per hour (depending on model and mesh size), making it ideal for industrial-scale production.
- Low Noise & Dust Control: Equipped with sealed covers and vibration-dampening mounts, the machine operates below 75 dB, and optional dust collection ports ensure a clean working environment.
- Easy Screen Change: Quick-release clamps allow mesh replacement in under 5 minutes without tools. The tensioning system ensures uniform screen tension for consistent sieving accuracy.
- Customizable Specifications: Available in stainless steel or carbon steel, with 1-5 layers, mesh sizes from 2 to 500 mesh, and voltage options to match your local power supply (380V, 220V, 440V, etc.).
- Minimal Maintenance: All bearings are sealed and lubricated for life. The simple mechanical design reduces wear and tear, and our factory provides a complete spare parts list for easy replacement.
Technical Specifications
| Model | Screening Area (㎡) | Layers | Motor Power (kW) | Dimensions (mm) | Capacity (TPH, 200 mesh) |
|---|---|---|---|---|---|
| BLS-1000 | 1.0 | 1-3 | 1.5 | 1500×1200×1100 | 0.5-1.5 |
| BLS-1500 | 2.25 | 1-4 | 3.0 | 2000×1700×1500 | 1.5-4.0 |
| BLS-2000 | 4.0 | 1-5 | 5.5 | 2500×2200×1800 | 3.0-8.0 |
| BLS-2500 | 6.25 | 1-5 | 7.5 | 3000×2700×2100 | 5.0-15.0 |
Note: Capacity depends on material characteristics, mesh size, and moisture content. Custom models are available upon request.
Why Choose Our Square Tumbler Sieve for Calcium Carbonate?
- Gentle Particle Handling: Unlike vibratory screens that can break friable calcium carbonate particles, the tumbler's low-impact motion preserves the crystalline structure, reducing fines and ensuring a higher yield of target-size product.
- Consistent Sieving Efficiency: The unique gyratory motion combined with a ball tray or ultrasonic system (optional) prevents blinding and pegging, even with sticky or ultra-fine powder. Sieving efficiency consistently exceeds 95%.
- Versatile Application: Not limited to calcium carbonate—our machine also excels in sieving quartz, feldspar, silica, alumina, graphite, and many other industrial powders. Change the mesh and you can adapt to different particle sizes.
- Global Compatibility: We ship to North America, South America, Europe, Africa, Oceania, the Middle East, and Asia. Our machines are designed to meet international voltage and frequency standards (50Hz/60Hz).
- Factory Direct Support: As a manufacturer with over 26 years of experience, we offer full technical documentation, video tutorials, and remote troubleshooting. Our warehouse in Hengshui, Hebei, ensures fast delivery to Tianjin, Qingdao, Shanghai, or Foshan ports.
Trusted by global clients across 20+ countries, our Square Tumbler Sieve has been used in calcium carbonate grinding plants, mineral processing facilities, and chemical factories. With annual exports exceeding US$5 million, we are committed to delivering reliable, cost-effective screening solutions. Each machine undergoes a 24-hour factory test run before shipment to ensure trouble-free operation.

Frequently Asked Questions
Q1: What is the maximum mesh size available for this machine?
A: Our square tumbler can accommodate mesh sizes from 2 mesh up to 500 mesh. For ultrafine screening (400-500 mesh), we recommend using an ultrasonic deblinding system, which is available as an optional upgrade.
Q2: How do I choose the number of layers?
A: The number of layers corresponds to the number of particle size fractions you need to separate. For example, a 2-layer sieve can produce three grades: oversize, mid-size, and undersize. If you only need to remove oversize material, a single layer is sufficient. We can help you design the optimal configuration.
Q3: Can this machine handle sticky or moist calcium carbonate?
A: Yes, but we recommend adding a ball tray (bouncing balls) or a cleaning brush system to prevent screen blinding. For extremely sticky materials, pre-drying is advised. Our machine can also be equipped with a heating system to reduce moisture adhesion.
Q4: What is the noise level during operation?
A: The machine typically operates at 70-80 dB(A), depending on the model and load. Optional soundproof covers can reduce noise to below 65 dB(A). We comply with CE noise standards (where applicable).
Q5: How often does the screen mesh need to be replaced?
A: Screen life varies based on material abrasiveness and usage. For calcium carbonate (Mohs hardness ~3), a standard stainless steel mesh can last 6-12 months with proper maintenance. We recommend inspecting the mesh every 2000 operating hours.
Q6: Do you provide spare parts and after-sales support?
A: Yes, we maintain a comprehensive inventory of spare parts including screens, gaskets, motors, and bearings. Support is available via email, phone, and video call. We can also dispatch engineers for on-site training (travel expenses apply).
Q7: What is the delivery time for a standard model?
A: Standard models (BLS-1000, BLS-1500) are typically shipped within 15-25 working days after receiving the deposit. Customized machines may take 30-40 working days. We ship from Tianjin, Qingdao, Shanghai, or Foshan ports.
Q8: Can I test the machine with my own material before purchasing?
A: Absolutely! We offer free sample testing in our factory. You can send us 5-10 kg of your calcium carbonate powder, and we will provide a detailed sieving report with efficiency and capacity data. Alternatively, we can arrange a video demonstration of a similar machine.
