PTMS magnetic separation

what is magnetic separation method for concentration of ore?

Under the action of a certain temperature, the permanent magnet iron remover chemically acts on the surrounding medium (such as oxygen in the air, additive sulfur in the cutting fluid, chlorine, etc.), and forms a compound with low hardness on the outer surface of the tool, which is easy to be chipped. The tool wear is lost due to friction with the workpiece, and the resulting tool wear is called chemical wear. The wear of the permanent magnet suction hanger of Qingdao shot blasting machine mainly occurs under the condition of higher cutting speed.

(1) When the new sharpening tool is put into use during the early wear of the permanent magnet suction hoist, the actual contact area between the flank face and the workpiece is small, the positive pressure received per unit area is large, and after the sharp grinding The flank surface of the flank is uneven, and the tool wear speed is very fast. During this period, it is called the pre-wearing period of the tool. The hook-type shot blasting machine permanent magnet suction tool cutter sharpens the oil-stone blade with fine-grained abrasive grains in the future. Grinding the surface of the grinding surface can significantly reduce the amount of wear of the tool in the early stage.

(2) After the pre-wearing of the permanent magnet suction hanger, the contact area between the flank and the workpiece increases, the pressure on the unit surface and the upper part is gradually reduced, and the micro-rough appearance of the flank of the tool has been smoothed. Therefore, the wear rate becomes slower, and this period is called the normal wear period of the cutter. The American Red Maple permanent magnet suction hanger is a useful working period of the cutter.

(3) When the permanent wear of the permanent magnet suction device is increased to a certain limit, the cutting force and cutting temperature of the iron remover will increase sharply, and the wear rate of the tool will increase until the loss of cutting ability is reached. This period is called sharp wear. During the period of rapid wear of the permanent magnet suction hoist, the tool continues to be regarded as a small loss, which not only ensures the quality of the machining, but also speeds up the consumption of tool data. If the blade is cracked, the loss is even greater. For example, permanent magnet suction hoist tools must be replaced before entering the period of sharp wear.
