The interior of the vertical mill is located at the air outlet, and the wear is particularly serious, and the position where the wear is more serious is located below 1-1.5 meters from the barrel of the coal mill. Generally, 20mm thick ceramic welding plates or 7070 (20+5) are used. Hemispherical ceramic welded plate, the hemispherical design can play a certain impact resistance. Use 5mm ceramic sheets or 10mm studs to weld ceramic linings at positions above 1-1.5 meters of the cylinder.
Because the top of the coal mill is not easy to construct, both the stud welding lining plate and the ceramic sheet can be used, and room-temperature glue can be used. Most of the separators use 5-10mm ceramic sheets. Both the welded ceramic lining plate and the ceramic sheet can be used for the inner supporting steel frame of the coal mill.
Weldable impact-resistant ceramic liner is developed on the basis of our many years of work and experience. The ceramic adopts a unique formula of 95% Al2O3 adding a variety of wear-resistant materials. It is dry-pressed and has high density, high toughness, and wear resistance. Features.
The wear resistance of the weldable impact-resistant ceramic liner produced by our company is 266 times that of manganese steel and 171.5 times that of high-chromium cast iron.
Wear-resistant ceramic lining plate is a wear-resistant, impact-resistant, and corrosion-resistant material for industrial use. The thermal expansion coefficient of viscose is between steel and ceramics, which can well adjust the extrusion of ceramics due to the inconsistency of thermal expansion between ceramics and steel. ; At the same time, a variety of flexible fibers are added to the adhesive to maximize the long-term operation of the ceramic in the vibration, thermal expansion, and cold contraction environment without falling off.
