LFY-403E Automatic Drum Friction Machine (including: Faraday Drum)

Main application
Under laboratory conditions, it is used to evaluate the electrostatic properties of the sample after it acquires charges through friction. It is used in experiments to measure the friction-induced charging of the sample and should be used in conjunction with a charge meter.

Technical indicators

The touchscreen operation display of the drum friction machine enables automatic rotation. No manual operation is required (there is no need for someone to hold the sample in the middle to prevent interference from human factors). The running time of the drum friction machine can be set, and it will automatically stop rubbing the sample when the time is up. 
2. Inner diameter of the drum: (65 ± 5) cm 
3. Drum depth: (45 ± 5) cm 
4. Rotational speed of the drum: above 46 revolutions per minute 
5. Drum diameter: 300mm and above 
6. Inner liner material of the drum: Polypropylene acrylonitrile standard fabric (as per GB/T 7568.5-2002) or nylon (choose either of the two friction fabrics for the drum) 
7. Number of drum blades: 3 pieces 
8. Air volume: More than 2 cubic meters per minute 
9. Temperature heating: (60 ± 10) ℃ 
10. Dimensions: 900mm × 780mm × 2100mm (including the bracket)
