• What are the advantages of a circular vibrating screen over a linear screen and a rotary vibrating screen?

  Higher Efficiency: Materials are evenly dispersed across the screen surface, eliminating accumulation and dead zones. The screening efficiency for the same material is 20%-30% higher than a linear screen and 15%-25% higher than a rotary vibrating screen (for example, when screening 100-mesh flour, the hourly output can reach 8-12 tons/hour, compared to only 5-7 tons/hour for traditional screens).
  More Stable Accuracy: The amplitude and frequency can be infinitely adjusted via a frequency converter to accommodate different particle sizes (such as fine powder, coarse particles, and sticky materials). The screening accuracy error is ≤1% (compared to 3%-5% for traditional screens), and the screened material remains intact (especially suitable for fragile items such as plastic particles and food granules).
  Lower Noise: Operating noise is ≤75dB (compared to approximately 85-90dB for traditional rotary vibrating screens), meeting European and American factory noise standards and eliminating the need for additional soundproofing.

• The materials we screen are sticky (such as wet coal and starch), which are prone to screen clogging. Can your equipment solve this problem?

  Yes. We offer three custom designs for sticky materials: The screen features a "self-cleaning structure": Optional bouncing balls (rubber or silicone, tailored to the material's hardness) or an ultrasonic screen cleaning device instantly remove stuck materials from the screen aperture, reducing clogging by over 90%. The screen's tilt angle is adjustable (0-5°): Adjusting the angle accelerates material flow and prevents stagnation on the screen surface. Anti-stick coatings (such as Teflon) are applied to material-contacting parts to reduce material adhesion. This is particularly suitable for sticky materials (such as wet starch and resin particles) in the food and chemical industries.

• Can the equipment's processing capacity meet our production capacity requirements? If production capacity increases in the future, can it be upgraded?

  First, we customize the screen specifications based on your material characteristics (particle size, moisture content, bulk density) and target production capacity. Currently, standard models offer throughput capacities of 0.5-50 tonnes/hour (e.g., a 1200mm diameter model offers 1-5 tonnes/hour, while a 2000mm diameter model offers 10-25 tonnes/hour). For higher capacity requirements, we can customize a multi-layer stacked design (up to 6 layers) or connect multiple units in parallel, enabling single-line throughput exceeding 100 tonnes/hour. Future capacity increases eliminate the need for complete machine replacement: upgrades can be made by increasing the number of screen layers, upgrading motor power (supporting a 20% increase for the same frame size), and optimizing feed and discharge interfaces, reducing secondary investment costs.

• We need to screen a variety of materials (such as ores and foods of varying particle sizes). Can a single device accommodate these?

  It can achieve "multiple uses with one machine." Our circular swing screen features a modular design: the screens can be quickly replaced (snap-on fastening, tool-free, and completed by one person in less than 5 minutes). It supports switching between screens of varying mesh sizes (10-500 mesh) and materials (stainless steel woven mesh, perforated mesh, and nylon mesh). The feed inlet is equipped with a "divider" to adjust the material distribution width to meet the dispersion requirements of materials of varying particle sizes. The discharge port can be configured with multiple grading outlets (e.g., 2 levels for a single screen layer, 4 levels for a third screen layer). This allows a single device to perform "coarse screening, fine screening, and grading," eliminating the need to purchase separate equipment for different materials.

• Our production environment requires explosion-proof protection (such as in the chemical and pharmaceutical industries). Can the equipment be designed for explosion-proof use?

  We support fully explosion-proof customization, complying with EU ATEX and North American Class I/II Division certification standards. The motors are explosion-proof (Ex d IIB T4 Ga, upgradeable to meet hazardous area levels). The electrical system (inverter, control cabinet) is explosion-proof and sealed, and cables are routed through explosion-proof conduit. For contact parts involving flammable materials (such as plastic particles or solvent mixtures), anti-static materials are used and grounded to eliminate the risk of static sparks.

• Is the XIANFENG circular swing screen compatible with China's voltage and frequency standards? Does it have relevant certifications?

  It is fully compatible and CE certified. It supports mainstream global voltages (110V/220V/380V/415V) and frequencies (50Hz/60Hz) and can be customized to your target market (e.g., North America, Europe, Southeast Asia, etc.). The motor features IP54 protection, making it suitable for high-temperature, dusty industrial environments and ensuring stable operation under the local power grid.
