Hi, i mounted them to PCB cylinder but i recommend to mount them into Steel pipe from outside.. you will get boost because one side is by magnetism closed and second which is open will be much stronger, I had 8 poles of magnets More poles, higher frequency - better for smaller particles.. for big particles is enough less frequency
I think , it is possible, In this video you can see that alternate magnetic field created with rotating magnet (South - North pole) which react with gold, ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-R1IXg3km4jY.html There is the best sorting materials with eddy current (It depend on conductivity and shape): 1. Aluminium 2. Magnesium 3. Copper 4. Silver 5. Zinc 6. Gold
New Robotic separation video - ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-qCqqmJ3WlV0.html Separating only plastic, glass, aluminium can and ferrous can, because of COVID. :)
only DC motors, for conveyor belt , , for speed conveyor belt - about 400 rpm, and for the slow (upper) conveyor 100 rpm, for magnetic cylinder - eddy current generator - about 1400 rpm because of bearing friction, but it need about 2500-3000 rpm for thinner pieces (MY 6812 12V 3000 rpm, 120W)
I am working on Robot + camera : separating Plastic, Glass, Paper, and Magnetic separator will separate Tetrapack, aluminium can, ferrous can Robot will be mounted on the first conveyor (upper) DEADLINE: 04/2020
Hello Dominik, Congratulations for what you do on waste recycling. I work with my friends from the university in sustainable development on a similar project but we can not differentiate between types of plastics. Can you share the arduino code on this part? we can show you what we have done and how it works. We are open to share our knowledge.
Eddy current cylinder is not so good designed.. (only plastic PVC cylinder with magnets) if you mount magnets on steel (not plastic) tube with thickness of 4mm (4mm on my magnets, it depends on magnet powers), you can get about 50% more power, because, you reduce magnetic resistence. Information about construction and more is available in this files.. uloz.to/file/6TwiBsBAsoiw/waste-separating-rar
mount magnets on the rotor but each magnet has different rotation - first has north, second south, next north, and so on... If you rotating this rotor, you create eddy currents which are only alternate magnetic field.
@@MemorialSEMUGEN more magnetic force - higher gauss surface also can help, but nessesary is higher frequency.. bigger ALU plates can be separated even with 500Hz frequency In the industry some eddy current separstors have 20kHz 30kHz frequency for separating Cu copper wires particles. So depends on size and shapes you want to separate.
Hello, I would really like to ask you a couple questions about this project. We are a business in the US that could use your help and we would be willing to throw some money your way for the trouble.
