With the continuous advancement of China's industrialization process, the development of the steel industry is also growing day by day, and the development of the steel industry cannot be separated from the mining and beneficiation of iron ore. The mining and beneficiation of iron ore require the use of complete sets of iron ore beneficiation equipment. This article will introduce the types and operating steps of iron ore beneficiation equipment.
1、 Types of iron ore beneficiation equipment
1. Grinding machine
A grinder is a type of iron ore beneficiation equipment mainly used for grinding ore to achieve a certain fineness, which is convenient for subsequent beneficiation operations. There are many types of grinding machines, including ball mills, rectangular mills, cone mills, etc.
2. Magnetic separator
A magnetic separator is a device that uses magnetic substances to beneficiate minerals, mainly used to select magnetic minerals from iron ore. There are also many types of magnetic separators, including wet magnetic separators, dry magnetic separators, and high gradient magnetic separators.
3. Flotation machine
A flotation machine is a device that utilizes the differences in mineral surface properties for beneficiation, mainly used to select non magnetic minerals from iron ore. There are also many types of flotation machines, including mechanical flotation machines, air flotation separators, centrifugal flotation machines, etc.
4. Heavy medium concentrator
A heavy medium beneficiation machine is a device that utilizes the difference in mineral density for beneficiation, mainly used to select heavy minerals from iron ore. There are also many types of heavy medium beneficiation machines, such as spiral separators, centrifugal separators, and heavy medium beneficiation tanks.
2、 Operation steps of iron ore beneficiation equipment
1. Crushing of ore
After mining, iron ore needs to be crushed through crushing equipment to achieve a certain degree of fineness for subsequent beneficiation operations.
2. Grinding of ore
The crushed iron ore needs to be ground by a grinder to achieve a certain degree of fineness for subsequent beneficiation operations.
3. Magnetic separation of ores
After grinding, the iron ore needs to be magnetically separated by a magnetic separator to select the magnetic minerals.
4. Flotation of ores
The iron ore after magnetic separation needs to be flotation through a flotation machine to select non magnetic minerals from it.
5. Heavy medium beneficiation of ore
The iron ore after flotation needs to be processed through a heavy medium beneficiation machine to select the heavy minerals.
6. Drying of ore
The iron ore after heavy medium beneficiation needs to be dried through drying equipment to achieve a certain degree of dryness for subsequent storage and transportation.
3、 Conclusion
Iron ore beneficiation equipment is an essential equipment in the process of iron ore mining and beneficiation. There are many types of equipment, and each type of equipment has its own specific beneficiation principles and operating steps. When using iron ore beneficiation equipment, it is necessary to strictly follow the operating steps to ensure the beneficiation effect and normal operation of the equipment.
