Abstract
The present invention relates to a magnetic separation method of a material carrier with a conveying belt and an immobile magnet. Magnetic ores are respectively separated magnetically by an ore conveying dry magnetic separation sealing-tape machine with a lower sucking type magnetic pulley and a group of dry magnetic separation sealing-tape machines with upper sucking type magnetic pulleys. The magnetic separation method comprises the following steps of concentrated ore supply, continuous stratification magnetic separation, one time whipping, ore magnetic suction separation and adequate sorting separation. The quantity of selected dry tailings can achieve 90 to 95% of the mixing quantity of ore waste rocks. The magnetic separation method has the advantages of grinding enhancement, 2 to 5% of iron containing grade of the separated ores, small resource loss and waste, great production capacity, application for large, medium, small and old magnetic separation plants, etc.
Description
The present invention relates to the immobile magnetic separation method that the material vehicle of conveyor type is arranged of magnetite, is that solid is separated from solid, is applicable to other dry type partition methods of bulk material, for example is suitable for the separation of the bulk goods that the astigmatism package material handles like that; Sorting, particularly a kind of serial up-draft dry magnetic dressing process.
Sneak into the barren rock of 5-20% at present in the ore extraction process, to the separation of poor magnetic iron ore; Sorting generally mostly is to adopt methods such as wet magnetic separation and dried magnetic separation, be to adopt magnetic pulley to separate ore as dry magnetic dressing process, promptly in the adhesive tape conveyor great wheel, stud with permanent-magnet block and do magnetic separation, select the part ore, it generally is the great wheel place that magnetic pulley is arranged on the ore conveyor belts machine after the fragmentation, its magnetic effect belongs to suction mode down, be that magnet is arranged on the bottom of being inhaled ore, because inhaling ore, the effect of magnetic force on adhesive tape, is transported to next procedure with sealing-tape machine, barren rock is dished out can reach 50-60%, go into mill thereby improve, the ore ferrous grade 1-2% of magnetic separation, volume increase iron ore concentrate stone is had certain effect, but sorting poor effect when ubiquity magnetic pulley and done magnetic separation, form the magnetic net owing to hold ore between the magnet both positive and negative polarity, barren rock in the magnetic net is thrown and is not gone out, the barren rock of being pressed by the bottom of magnetic massive ore is also thrown and is not gone out, still be mixed among the ore, also have the barren rock of being dished out to take away the ore that part is not lived by magnetic, cause the resource loss waste, there is being the dried magnetic separation sealing-tape machine of the magnetic pulley of being mostly to be arranged in parallel, exist the dried magnetic separation sealing-tape machine of every magnetic pulley construction feeding system equipment separately of supplying with, complex process, quantities is big, investment is big, it is little to produce effects, shortcomings such as production capacity is low, for overcoming above-mentioned existing weak point, the present invention has designed a kind of series connection the up-draft dry magnetic dressing process of doing the magnetic separation sealing-tape machine has been set.
The purpose of this invention is to provide a kind of raising and go into mill, magnetic separation ore ferrous grade height, magnetic separates, sorting ore is abundant, and technology is simple, and series connection is provided with the up-draft dry magnetic dressing process of doing the magnetic separation sealing-tape machine.
