1) Corrugated surface corrosion: Spectral analysis found that the concentration of non-ferrous metal elements is abnormal, and the sub-micron-scale wear particles of many non-ferrous metal components are present in the iron spectrum. The lubricating oil has excessive water content and acid value overrun.
2) Shaft surface corrosion: Spectral analysis found that the concentration of iron is abnormal; there are many submicron particles of iron in the iron spectrum; the moisture overrun or the acid value overrun of the lubricating oil.
3) Spine external strain: iron-based cutting abrasive black oxide particles in the iron spectrum; tempering color on the metal surface.
4) Fretting wear on the back of the tile: Spectral analysis found that the iron concentration was abnormal; there were many iron-submicron wear particles in the iron spectrum; the moisture and acid value of the lubricating oil were abnormal.
5) Bearing external strain: cutting abrasive grains are found in the iron spectrum; the abrasive grain composition is non-ferrous metal.

The Mining Roadheader series products are suitable for non-explosive heading projects in the mining field.  They are provided for customers who are not allowed to use explosive methods in coal mines and tunnel engineering.  A series of products are widely used in coal mines, railway highway tunnels, water conservancy projects and other fields. The company's various types of roadheaders meet the customer's design of various sizes of roadways, tunnels, of shale, sandstone, mudstone, coal rock, coal and other rock tunnels and coal mine tunnels with a Platts hardness below 120Mpa.

At present, the roadheader has become the core equipment of mining mechanization and plays an extremely important role in the coal mining process. NHG comprehensively carried out the research and development of advanced technology and equipment for roadheaders in combination with advantageous resources. At present, EBZ100, EBZ132, EBZ160, EBZ180, EBZ230, EBZ260, EBZ280, EBZ300, EBZ320 and other more than 20 types of machines have been developed, and roadheader products have formed a good brand reputation and influence in the international market. The application of these products not only meets the needs of customers, but also effectively improves the service life and production efficiency of the roadheader.
