Problems solved by technology

[0003] In the process of recycling high-tech steel grinding wheel ash, in order to reduce energy consumption and ensure the quality of crude steel, it is necessary to select the grinding wheel abrasive grains in the grinding wheel ash before melting, and the most widely used method is magnetic separation. The method is to use a magnetic separator for magnetic separation, and we know that the permanent magnet drum in the traditional magnetic separator usually adopts the method of electromagnetic field magnetic separation. The structure of this device is relatively complicated, and it is not very convenient to install and use. The recovery rate is not high

Abstract

The invention relates to a permanent magnet pulley of a grinding wheel ash magnetic separator. The permanent magnet pulley comprises a pulley housing, a main shaft and a magnetic system, wherein the main shaft is penetrated through the center of the pulley, and the magnetic system is arranged in the pulley housing and is connected with the main shaft; and the magnetic system comprises a main magnetic pole, an auxiliary magnetic pole and a magnetic yoke. The permanent magnet pulley is characterized in that the same poles of the main magnetic pole and the auxiliary magnetic pole are alternatively arranged in the pulley housing, wherein the intensity of a magnetic field of the surface of the pulley housing is 100-500mT, and a wrap angle of the magnetic field is 120-135 degrees. The permanent magnet pulley has the advantages of realizing more accurate seperation of components such as grinding wheel abrasive particles and adhesives in grinding wheel ash and strong ferromagnetic steel cuttings by adjusting the range of the magnetic wrap angle of the permanent magnet pulley and the strength of a surface magnetic field, laying the raw material foundation for increasing the quality grade of regenerated high-speed tool steel and increasing the concentrate grade.

Description

technical field [0001] The invention relates to a magnetic separator, in particular to a permanent magnet drum of a grinding wheel gray magnetic separator, and belongs to the technical field of metal separation machinery components. Background technique [0002] During the grinding process of high-tech steel, a large amount of grinding wheel dust will be generated, and its main components are steel shavings, cutting oil, and grinding wheel abrasive grains. In recent years, due to the soaring price of international iron ore, the price of high-tech steel has also remained high. As an important renewable resource, high-tech steel grinding wheel ash has been increasingly valued by metal recycling companies. [0003] In the process of recycling high-tech steel grinding wheel ash, in order to reduce energy consumption and ensure the quality of crude steel, it is necessary to select the grinding wheel abrasive grains in the grinding wheel ash before melting, and the most widely use...
