The grinding table is one of the key parts of the vertical roller mill. It is mainly composed of a table body, liner plate, pressure block, retaining ring, scraper plate, wind ring, wind deflector, and other components. CHAENG optimizes the casting technology and adopts the advanced water glass sand molding technology to make the base of the grinding plate evenly stressed, increase the bite angle between the grinding table and rollers, and avoid the erosion of the non-wear-resistant surface of the grinding table.
According to customer requirements, CHAENG select the appropriate wooden mold for modeling design, use CAE simulation casting before actual casting, in strict accordance with the technological process of wooden mold – modeling – smelting pouring – heat preservation –sand cleaning and out of the pit – heat treatment – rough machining and fine machining – packaging and delivery, cast grinding table with high quality.
1. Optimizing and matching based on the casting technology, adopting the most advanced water glass sand molding process, overcoming the deficiency of previous structure to make the grinding table uniform stress, increasing the nip angle between the grinding table and grinding roller to avoid brush erosion of the wear-resisting surface ;
2. Advanced machining equipment to ensure high surface finish of vertical grinding table;
3. Perform a non-destructive inspection of the force surface before leaving the factory, which can ensure the internal and external quality of the grinding table is qualified in industry standard;
With the development over the years, the products of CHAENG have been sold well in various provinces and cities in China and exported to many countries and regions such as Europe, America, and Germany.
