As the basic raw material of modern industry, the mining and processing efficiency of iron ore directly affects the stability and economy of the steel industry chain. In the process of iron ore beneficiation, iron removal is a key step to ensure the purity of ore, but the long-standing technical defects of traditional iron removers have become a bottleneck for the development of the industry. In recent years, the application of new intelligent equipment represented by MINGDER foreign body removal robot has provided a new technical path to solve this problem and injected new momentum into the transformation and upgrading of the industry.

1. Technical bottleneck of traditional iron remover

The working principle of traditional iron remover (such as electromagnetic iron remover, permanent magnetic iron remover, etc.) relies on magnetic field to absorb ferromagnetic impurities. Although its original design can meet basic needs, it exposes a series of problems in actual application:

For magnetite transportation line, the strong magnetic characteristics of ore itself make the magnetic field of iron remover a double-edged sword-it must absorb mixed iron objects and avoid misjudging precious ore as impurities. This is more obvious in the transportation of weakly magnetic hematite: although increasing the magnetic field strength can enhance the iron removal effect, it aggravates the magnetic agglomeration of the ore, which in turn affects the subsequent grinding efficiency.

Traditional equipment has almost zero ability to identify non-ferromagnetic impurities (such as aluminum, copper, plastic, rubber, etc.), and the types of foreign matter mixed in modern iron ore mining are becoming increasingly complex, resulting in a large number of non-ferrous impurities entering the subsequent process, affecting smelting efficiency and product quality.

Electromagnetic iron removers need to be continuously powered on to maintain the magnetic field. The average daily power consumption of a single device exceeds 200 kWh, and the surface of the magnetic rod is easily worn by the ore, requiring shutdown and replacement of parts every quarter. Taking a mineral processing plant with an annual output of one million tons as an example, the annual operation and maintenance cost of the iron removal link alone accounts for more than 15% of the total equipment investment.

The physical limitation of the installation height buries greater hidden dangers. In order to maintain an effective magnetic field, the iron remover must be close to the conveyor belt. This design directly pushes the equipment to the risk front line. For example, if the discarded steel components are adsorbed and stuck in the gap between the equipment and the conveyor belt due to their large size, the high temperature generated by the instantaneous friction will not only melt the magnetic rod group, but also cause the conveyor belt to break, resulting in the paralysis of the entire production line.

2. Technological breakthrough of foreign body removal robot

When magnetic screening reaches the physical limit, the MINGDER intelligent foreign body removal robot integrated with the intelligent sorting system has built a new impurity processing paradigm through the three-level technological leap of "perception-decision-execution":

Multi-dimensional perception system

Integrated hyperspectral imaging and 3D visual scanning (construction of a three-dimensional model of foreign bodies) to achieve 1cm-level accuracy of all categories of impurities detection.

Adaptive decision algorithm

The dynamic optimization model based on deep learning can analyze ore flow data in real time and autonomously adjust the robot arm's grasping path and strength.

Modular execution unit

Equipped with multifunctional end tools such as vacuum adsorption, flexible grippers, and high-pressure air spray, it can switch the removal mode for foreign bodies with different physical characteristics.

3. Industrial value brought by technological upgrades

MINGDER foreign body removal robot effectively reduces equipment loss and iron ore raw material damage for hard foreign bodies such as metal debris and stones mixed in the iron ore conveyor belt transportation, extending the life of the conveyor belt by 20% and reducing the frequency of crusher maintenance by 45%. At the same time, by reducing the collision and wear between iron ore and foreign bodies, the raw material damage rate is reduced from 3.2% to 1.5%, saving about 18,000 tons of high-grade iron ore loss annually, which is equivalent to reducing the waste of raw materials by 2.4 million yuan per year for a single production line. This technology also prevents flammable materials such as wood chips and plastics from entering the high-temperature processing link, reduces the risk of fire on the production line, and helps iron ore transportation achieve the goal of "zero non-stop", saving mining companies more than 6 million yuan in equipment maintenance and accident handling costs each year, significantly improving production safety and resource utilization.

4. Born to the new: the future vision of clean transportation in mines

When the first electromagnetic iron remover was used in Swedish iron ore in 1923, humans might not have expected that the sorting technology a hundred years later would move towards the intelligent path of "demagnetization". When the development of a single physical effect approaches its limit, the only way is to break through the barriers of disciplines and find a breakthrough in the integration of light, magnetism, electricity and computing. The removal of impurities on the iron ore transportation line is actually a microscopic mirror of the transformation and upgrading of the entire manufacturing industry.

The intelligent revolution in the iron ore industry is unstoppable. The technological breakthrough represented by the MINGDER foreign body removal robot is not only the iteration of a single device, but also a fundamental subversion of traditional production logic. Mines have begun to use the "AI eye" to examine each grain of ore and use the "mechanical hand" to accurately remove impurities.
