In other implementations, when the magnetic sheet in field generator for magnetic is calutron, blanking mechanism can be electricity degaussing gear, it is preferable that blanking mechanism includes electricity degaussing gear and scraper plate.Such as, in one embodiment, electricity degaussing gear includes the control module that can control the magnetic force of the magnetic board in field generator for magnetic.When certain block electromagnet rotates to feeding zone, control module and control the magnetic field size of this electromagnet and make this electromagnet not produce magnetic field, so that select mineral aggregate to be no longer influenced by the attraction of magnetic force, thus can not be attached to, separation tube inwall splits away off.
As shown in Figure 2 A and 2 B shown in meaning property, the first material-receiving device 263 can be arranged on the splicing groove below blanking mechanism.Preferably, splicing groove tilts gradually downward from the feed end of separation tube so that the mineral fallen in groove can under gravity gradually landing to outlet, enter the first discharging opening.
The above; being only the present invention preferably detailed description of the invention, but protection scope of the present invention is not limited thereto, any those familiar with the art is in the technical scope of present disclosure; the change that can readily occur in or replacement, all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain of claims.
