According to the market demand of Wear Resistant Castings, some users want to improve the service life of roller and millstone lining plates and reduce the maintenance load of the mill, and some use new composite lining plates, such as the wear-resistant surfacing lining plate we are talking about today.

1. For cement plants, which material should be used for grinding disc and roller liner?

If the materials on site are mainly limestone and the other materials are less doped, I suggest using high chromium lining board. If steel slag is added to the material, which is very difficult to grind, surfacing welding or ceramic lining plate should be used.

2. How thick is the overlay welding of the vertical mill millstone tile?

In general, the surfacing thickness is 1/3 of the total thickness. Too thick overlaying layer is easy to cause large area falling off.

3. What is the service life of the millstone tile?

At present, the main factors affecting the service life are the composition of the materials being ground, the normal wear of materials that are easy to grind and the wear rate of materials that are difficult to grind. It is reasonable to carry out lining welding every 2,000 hours according to the technological requirements. The so-called guaranteed service life also requires secondary or tertiary repair welding and price superposition.
