为了提高鼓式磁选机的生产率须要在磁选机的给矿区形成深磁场和保证磁性产品输送区磁力比较强。理论和实验研究表明提高鼓式磁选的生产率与磁系的磁极最佳间距有关。同时给料区磁系磁极的最佳间距应该比磁性产品运输区的磁极间距大。磁极的间距取决于工作间隙的导磁性,工作间隙的导磁性在不同的区间是不相同的,选别物料中磁铁矿含量的不同也引起它的变化。试验确定磁性产品运动的平均
In order to improve the productivity of the drum separator, it is necessary to form a deep magnetic field in the magnetic separator to the mining area and ensure that the magnetic force in the delivery area of the magnetic product is relatively strong. Theoretical and experimental studies show that increasing productivity of drum magnetic separation is related to the optimal spacing of the magnetic poles of the magnetic system. At the same time, the optimum spacing of the magnet system poles in the feed zone should be larger than the pole spacing in the transport zone of the magnetic product. Pole spacing depends on the work of the gap of the permeability, the work of the gap between the permeability in different intervals are not the same, sorting materials in the magnetite content also caused its change. The test determines the average magnetic product movement
