The power consumption for certain models is specified as 5.5+3.0+0.55*2 kW, indicating a multi-motor setup that may include separate drives for the conveyor and the magnetic rotor. Verifying the motor brand is essential, as listings often mention reputable brands like Siemens or Schneider, or locally famous Chinese brands, which can significantly influence the machine’s durability and energy efficiency.

The physical dimensions and weight of the equipment are also vital for site planning, with some models measuring approximately 3670x2000x1285 mm and weighing around 1400 kg, while others may weigh up to 5 tons. The feeding size is often customizable, allowing the machine to be adapted to different waste stream characteristics. Additionally, the bearing quality, such as the use of NSK bearings, is a key indicator of the machine’s ability to withstand continuous operation and heavy loads. Buyers should verify the automation level, as automatic systems reduce labor costs and improve consistency, while also checking for the availability of engineer guidance for installation to ensure proper setup and calibration.

Compliance and Safety Documentation

Compliance with international standards is a prerequisite for safe and legal operation, with CE certification being a common requirement for machines sold in European markets. Buyers should request valid CE certificates to ensure that the equipment meets essential health and safety requirements, including electrical safety and machinery directives. ISO 9001 certification is also frequently cited, indicating that the manufacturer adheres to a quality management system that ensures consistent product quality. However, buyers should verify the validity of these certifications directly with the issuing bodies, as listing them on a product page does not guarantee current compliance.

Additional certifications such as SGS, BV, and RoHS may be present, offering further assurance of material safety and manufacturing quality. RoHS compliance, in particular, is important for ensuring that the machine does not contain hazardous substances, which is relevant for environmental regulations and worker safety. Buyers should also inquire about machinery test reports, which provide documented evidence of the machine’s performance and safety under controlled conditions. These reports can serve as a valuable reference during the acceptance phase of the procurement process, helping to verify that the delivered unit meets the agreed-upon specifications.

Cost Drivers and Commercial Terms

The cost of an eddy current sorting machine is influenced by several factors, including the processing capacity, motor quality, and level of customization. High-capacity units with advanced automation and premium components like Siemens motors will naturally command higher prices.
