1. What is the Stacked Spiral Sludge Dewatering Machine?

A mechanical dewatering unit that uses stacked spiral/screw elements to remove water from sludge, reducing waste volume and improving downstream handling. It is designed for continuous operation in wastewater, sludge processing and other industrial applications.

2. What processing capacity does the machine have?

The specification lists a production capacity of 200 pcs/min. Note: "pcs/min" appears to be a templated field (possibly for other product types). For sludge dewatering, capacity is normally expressed as sludge flow (m3/h) or dry solids (kg/h). Confirm actual sludge throughput and cake solids with the supplier.

3. What are the electrical requirements and power consumption?

Rated power is 3 kW and the voltage options listed are 220/380 V. Confirm whether the 220 V is single-phase or 380 V three-phase and any local electrical requirements prior to installation.

4. What are the machine's main components and materials?

Core components listed are gears, motor and bearings. Contact parts are typically made from corrosion-resistant materials (stainless steel or coated steel) — verify exact construction and grades with the manufacturer for compatibility with your sludge chemistry.

5. What are the machine dimensions, weight and packaging details?

Single package size is listed as 230 x 80 x 150 cm. The spec lists Weight: 5000 KG and Single Gross Weight: 500.000 KG (this appears inconsistent). Because of these discrepancies, confirm the shipped weight and any special lifting/foundation requirements with the vendor.

6. What level of dryness (cake solids) can I expect?

The datasheet does not specify cake solids. Actual dryness depends on sludge type, feed solids, polymer dosing and operating settings. Typical spiral dewatering systems can produce a wide range of cake solids; request lab or site trial data from the supplier for an accurate expectation.

7. Which applications is this machine suitable for?

Intended applications include wastewater treatment plants, sludge processing facilities, environmental remediation projects and industrial waste management. (The spec also lists "toilet tissue manufacturing" which appears to be a template error — confirm intended use with the vendor.)

8. Does the machine come with quality inspection and test documentation?

Yes — the specification states that a video outgoing inspection is included and a machinery test report is provided with the unit.

9. What are the installation and site requirements?

Prepare a suitable foundation capable of supporting the machine's weight, provide the specified electrical supply, ensure crane or forklift access for placement (machine is heavy), arrange inlet/outlet piping and provide room for maintenance access. Exact civil and utility requirements should be obtained from the supplier.

10. What routine maintenance is required?

Regular checks and lubrication of gears and bearings, inspection of the spiral element and wear parts, motor maintenance, cleaning of screens or drainage paths, and periodic replacement of consumable items. Follow the manufacturer’s maintenance schedule for intervals and procedures.

11. Are spare parts and service available?

The machine uses standard components (gears, motors, bearings). Ask the manufacturer or distributor about spare parts kits, lead times, and on-site service or commissioning support before purchase.

12. What safety features should I expect or install?

Typical safety features include guards over moving parts, emergency stop buttons, electrical protection, and access interlocks. Ensure machine guarding and local safety requirements (lockout/tagout, PPE) are implemented per site standards.

13. How do I select the right model for my sludge type?

Provide the supplier with sludge characteristics (flow rate, % solids, particle size distribution, organic content), desired cake dryness, polymer usage (if any) and footprint/installation constraints. The vendor will size and configure the spiral stack and drive accordingly.

14. What warranties and certifications come with the machine?

The specification does not list warranty terms or certifications. The datasheet does note a machinery test report is provided. Request written warranty details, CE/ISO or other applicable certifications and any factory acceptance test documentation from the supplier.

15. How is the machine shipped and what packaging can I expect?

A single package size is listed (230 x 80 x 150 cm) and a gross weight entry is provided in the spec. The vendor states a video outgoing inspection is performed; confirm final packaging method, transport weight and any special crating requirements for international shipping.
