magnetic separators

permanent magnetic separators. rare-earth magnetic circuits commonly exhibit a magnetic attractive force 20 to 30 times greater than that of conventional ferrite magnets. this development has provided for the design of high-intensity magnetic circuits that operate energy-free and surpass the strength and effectiveness of electromagnets.

production of net-shape mn-al permanent magnets by

the as-cast bulk alloy ingot 5 kg was prepared for ball milling by crashing it into 2 5 mm chips. the milling was performed in a planetary ball mill pulverisette 6, fritsch at a rotation speed of 250 rpm with a powder to balls mass ratio of 1:10.

hydrogen decrepitation and recycling of ndfeb-type

the best sintered magnet was produced by very lightly milling the powder 30 min, roller ball mill , aligning, pressing and vacuum sintering at 1080 for 1 hour. the magnetic properties of this magnet were: bh ^ = 290 kjm"3 kjm"3 , br = 1240mt mt and //cj = 830 kam"1 kam"' ; representing decreases of 15%, 10%, and 20% respectively, from the properties of the initial magnet.

what is a rare earth magnet? pro tool reviews

permanent rare earth magnets are mounted to the rotor, and as electricity runs to the magnets, the polarities of the magnets drive the shaft. brushless motors tend to be more precise, quieter, more durable, cooler-running, and more powerful than brushed motors.

production of net-shape mn-al permanent magnets by

the main goal of this work is the adoption of additive manufacturing for the production of inexpensive rare-earth free mnal-based permanent magnets. the use of more advanced binder-free additive manufacturing technique such as electron beam melting ebm allows obtaining fully-dense magnetic materials with advanced topology and complex shapes.
