Description
Technical field
The present invention relates to a kind of preparation equipment, especially a kind of high field intensity high-gradient permanent magnetic separator that sorts magnetic mineral and/or weak magnetic mineral.
Background technology
Because the developing rapidly and change of science, technology and society economic activity, the exploitation and the consumption of mineral resources increase rapidly, explored various rich ore reserves are fewer and feweri, if lean ore is not exploited and is used for replenishing the deficiency of rich ore, will seriously hinder the normal development of human society because of the scarcity of mineral resources.But the exploitation of lean ore need rely on high-new science and technology, adopts traditional science and technology and equipment exploitation lean ore will cause the great wasting of resources and environmental pollution.For this reason, develop and develop novel technique of preparing and preparation equipment is very urgent, and be rich in challenge.
Up to now, the magnetic induction intensity relative fixed of existing all kinds of permanent magnetic separators is difficult to sort the close mineral matter of magnetic or poor to the separating degree of the close mineral matter of magnetic, does not reach the requirement that separates and sort; Simultaneously, the increase that the magnetic induction intensity of permanent magnetic separator can be in time and weaken final loss of excitation gradually; And, permanent magnetic separator only can be used for choosing at present and divide strongly magnetic mineral matter, it is relatively poor that weak magnetic or paramagnetic mineral matter are sorted separating effect, there is tangible application limitation, for example, the magnetic field intensity of existing all kinds of permanent magnetic separator magnetic separation parting surfaces can't reach more than the 0.8T (tesla), and it is little to present magnetic field gradient, the branch ferromagnetic substance can only be selected, the material of the weak magnetic of branch can not be selected.Although can reach the regional magnetic induction intensity of the part after some permanent-magnets process specific combination more than the 1.2T, its magnetic field gradient is also bigger, but because the restriction of prior art, equipment and material, this class combination does not at present also have to find can make diameter greater than the combination magnetic spare more than the φ 500mm, and choosing divides area very little, can only be used for breadboard trace and select separating tests, can't be used for suitability for industrialized production.
Chinese patent ZL97207074.5, ZL99233150.1, ZL99245569.3, ZL03215262.0, ZL03240242.2, ZL200320110040.9 etc. disclose with magnet and various assembly and have been assembled into a kind of pulley type magnetic roller, then with the magnetic roller as magnetic separation parts, set up into the different magnetic separator of various appearance forrns, it selects split is exactly the magnetic roller; The magnetic roll structure complexity of this form, the cost height, choosing divides area little, and the report of present rarely seen minor diameter (diameter is less than 150mm) magnetic roller is not seen the report of major diameter magnetic roller.In addition, existing permanent magnetic separator complex structure is unfavorable for installation and maintenance.
For saves energy, improve the income/investment of ore dressing, and improve the sorting usefulness of magnetic plant and efficiently sort weak magnetic substance or the close material of magnetic, realize the application of heavy industrialization, the invention provides a kind of permanent magnetic separator of high field intensity high gradient.
