The magnetic field strength of iron ore dry separator is generally required to be above 3500 Gauss. The selected ore is called medium ore, and the grade is generally about 20%. The main beneficiation process is as follows:
The raw ore is sent to the upper hopper, and the cloth is vibrated by the vibration motor. The output can be precisely adjusted by the hand wheel.
The magnetic roller of the dry magnetic separator is dragged by a speed control motor, and the speed of the speed is adjusted by a speed meter, which can control the output of the magnetic separator and the concentrate grade. The ore particles are sent to the upper magnetic roller for sorting via a conveyor belt. Because the ore particles are magnetic, they are immediately adsorbed on the magnetic roller by the strong magnetic field, while the gangue particles (debris, sand) are non-magnetic (weak magnetism) ), The strong magnetic force of the magnetic roller does not generate a suction force on it. With the rotation of the magnetic roller, the ore particles are always attracted to the magnetic roller, and the gangue particles are thrown out on the ore-blocking plate when the magnetic roller turns to the front position In the front (the grade of the concentrate can be adjusted by changing the size of the ore plate angle), the ore particles continue to fall into a collection hopper and are collected as concentrate products when they are brought to the demagnetization zone by the magnetic roller.
Because the gangue falling from the upper magnetic roller also contains some weaker magnetic particles, they will enter the lower magnetic roller to continue the magnetic separation. The magnetic particles of the finished product enter the second selection hopper to be collected as the finished product, which is thrown away. The discharged gangue is discharged through the tailings mouth, and the magnetic separation process is completed. Because the gangue in the original ore is discarded, the quality of the ore is improved.
