Equipment will be worn during material transportation. For continuous production enterprises, anti-wear is already a critical issue for safe production, especially in iron and steel plants, thermal power plants, cement, ports, and chemicals.
Alumina wear-resistant ceramic sheet is a form of wear-resistant that is economical and has an immediate effect. Its excellent wear-resistant performance is favored by all manufacturers. It is ubiquitous in power production, especially in the pulverizing system. Wear-resistant ceramic sheet model to ensure the service life of the equipment.
Anti-wear of coal mill barrel wall
The operating environment of the barrel wall of the coal mill is relatively poor. The temperature in this place is the place where the temperature of the coal mill is relatively high, and it should be around 220°C. Most of them think that the erosion and wear of this part is relatively serious, because the ceramics of the barrel wall of the coal mill are all broken. Starting from this position, it is recommended to use a 10mm thick ceramic sheet in the severely worn area, a 5mm thick ceramic sheet in the non-severely worn area, and a high temperature-resistant adhesive in the high temperature area to ensure that the ceramic does not fall off.
Anti-wear of a static ring of coal mill
The temperature of the operating ring of the static ring of the coal mill fluctuates in the range of 200-300 ℃, and the strong erosion aggravates the damage of this part. Because the temperature is too high, it is more important to choose high-temperature glue. In addition, it is not suitable to choose too thick ceramic sheets for this part, which is easy to fall off. In the experiment, we found that 10mm ceramic sheets are more reasonable for static ring anti-wear.
Anti-wear of coal mill separator
The separator of the coal mill is very good for anti-wear with ordinary ceramic sheets, and the operating temperature is 70 ℃-90 ℃ mixed air, so the ordinary 5mm alumina ceramic sheet is used for anti-wear in this part, and the service life is 6-8 years.
Anti-wear of the straight pipe section at the outlet of the coal mill separator
The operating environment of the straight pipe at the outlet of the separator of the coal mill is relatively bad. The high-speed airflow is mixed with coal particles, which strongly scours the pipe wall and causes this part to be worn out first. The temperature of the mixed air at 70°C-90°C is not very high, so the coal mill The ceramic type used in the straight pipe section of the separator can use a ceramic sheet of about 10-15mm to ensure the anti-wear requirement of the coal mill.
