Изобретение касаетс магнитного обогащени сыпучих материалов с различными магнитными свойствами, а именно с различной коэрцитивной силой.The invention relates to the magnetic enrichment of bulk materials with different magnetic properties, namely, with different coercive force.
Известны способы разделени ферромагнитных материалов по величине их коэрцитивной силы 1.Methods are known for separating ferromagnetic materials by the magnitude of their coercive force 1.
Такие способы основаны на измерении свойств каждого из раздел емых образцов, что дл мелких частиц непри.менимо из-за трудоемкости.Such methods are based on measuring the properties of each of the samples to be divided, which is inapplicable for small particles because of their laboriousness.
Наиболее близким по технической сущности к изобретению вл етс способ сепарации частиц по величине их коэрцитивной силы, включающий их размагничивание под воздействием переменного магнитного пол с последующим разделением их на две фракции 2.The closest in technical essence to the invention is a method of separating particles by the size of their coercive force, including their demagnetization under the influence of an alternating magnetic field with their subsequent separation into two fractions 2.
Однако в известном способе происходит отделение сильномагнитного высококоэрцитивного материала от слабомагнитного, причем этим способом одновре.менно с магнитожестким извлекаетс и магнитом гкий сильномагнитный материал.However, in a known method, a highly magnetic highly coercive material is separated from a weakly magnetic material, and this method simultaneously removes the magnetically strong highly magnetic material simultaneously with the magnetic hard material.
Це,1ью изобретени вл етс интенсификаци процесса сепарации ферромагнитных частиц.The first invention is to intensify the separation process of ferromagnetic particles.
Это достигаетс тем. что размагничивание ферромагнитных частиц осуществл ют переменным полем убывающей амплитуды, а оазделенне - в переменном поле со значением напр женности, при котором магнитом гкие частицы флокулируют. а магнитожесткие нри вращении выход т ii3 состава флокул.This is achieved by those. that the demagnetization of ferromagnetic particles is carried out by a variable field of decreasing amplitude, and osedelenne - in a variable field with a value of intensity at which the magnetically soft particles flocculate. and the magnetic hard rotate out of the composition of floccules ii3.
Размагничивание ферромагнитных частиц осуществл ют переменным полем убывающей напр женности, при которой разрущаетс остаточна намагниченность преимущественно магнитом гких частиц.The demagnetization of ferromagnetic particles is carried out by a variable field of decreasing intensity, at which the residual magnetization of a predominantly magnetically soft particle is destroyed.
