XBSY Decanter Centrifuge Sludge Dewatering Machine

The XBSY Decanter Centrifuge is a high-speed solid control centrifuge designed to separate solids from liquids in sludge streams. It provides efficient sludge dewatering for wastewater treatment and industrial processes such as mining, food & beverage, pulp & paper and chemical production.

Typical applications include municipal and industrial wastewater treatment, mining and mineral processing, food and beverage processing, pulp and paper production, and chemical manufacturing where solids/liquid separation and sludge volume reduction are required.

Models are designated under the LW series with bowl diameters ranging from 250 mm to 720 mm. Overall dimensions vary by model; specific length/width/height will be provided based on the selected diameter and configuration.

Bowl rotational speeds are adjustable within a range of approximately 2200–5000 rpm (model-dependent). The equipment features a differential/scroll ratio of 4.1, with adjustable differential speed to optimize solids conveyance and cake dryness for different sludges.

The centrifuge is available for three-phase power systems, commonly 380 V or 460 V, and can be configured for 50 Hz or 60 Hz operation to match local power supplies.

Cake moisture and overall dewatering performance depend strongly on sludge type, solids concentration, flocculant use, and operating settings. Performance should be evaluated with site samples or pilot testing — we can help size the machine and estimate cake dryness after reviewing sample tests.

Capacity depends on the selected bowl diameter, feed solids concentration, and sludge characteristics. Provide sludge flow, percent solids (TS/SS), and sample for lab or pilot testing so we can recommend the correct model and expected throughput.

Power consumption varies by model, motor ratings, speed and load. Detailed motor power and estimated energy use are provided on the quotation for the specific model and configuration you select.

The centrifuge is compact but typically requires a leveled concrete foundation with vibration isolation, proper inlet and discharge piping, electrical hookup to the specified three-phase supply, and safe access for maintenance. Exact footprint and installation instructions are provided with the selected model.

Routine maintenance includes scheduled lubrication of bearings, inspection of seals and wear parts, checking drive components and V-belts or couplings, cleaning the bowl and scroll as needed, and replacing liners/wear parts based on service conditions. A preventative maintenance schedule will be provided.

Yes—spare parts are available and we can supply common wear items. Overseas service engineers are available to support installation, commissioning and maintenance. Contact sales to arrange spare parts kits or field service.

Units are typically packed in wooden or steel cases for export. Common ports of dispatch include Shanghai and Tianjin, though other ports can be arranged. Lead time and shipping terms are provided on request.

The centrifuge has a robust design and can be configured with wear-resistant materials and liners for abrasive sludges. For very abrasive or unusually difficult sludges, we recommend discussing material options and conducting sample tests to confirm suitable configuration.

Yes. Common options include variable frequency drives (VFDs) for adjustable bowl and scroll speeds, PLC control panels, automatic alarm/protection features, and integration with polymer dosing systems and feed pumps for optimized dewatering.

Contact our sales team with the required process data (flow rate, percent solids, sludge characteristics) and, if possible, a representative sludge sample. We can provide model recommendations, quotations, and arrange lab or on-site pilot testing to verify performance.
