Grinding table is one of the key parts of the vertical roller mill. It is mainly composed of 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.
Vertical Mill Table Production Process – Quality Cast Steel Grinding Tables
Changcheng Cast Steel produces high-quality mill tables (grinding tables) for vertical roller mills, tailored to each customer's requirements. We select the right wooden pattern for the molding design and run CAE casting simulation before actual production. Every mill table is manufactured through our strictly controlled process chain:
From pattern design to the finished product, every stage is monitored to ensure consistent internal quality, precise dimensions and a long service life.
1. Optimized Casting Design & Advanced Molding Process Based on years of casting process refinement, we adopt the most advanced sodium silicate (water glass) sand molding technology. This approach overcomes the structural weaknesses of conventional designs, ensuring even stress distribution across the grinding table, a larger bite angle between the table and the grinding rollers, and effective protection of the wear surface against erosion.
2. High-Precision Machining Equipment Our advanced machining equipment delivers a high surface finish and tight dimensional accuracy on the vertical mill table working surface, ensuring reliable contact performance in operation.
3. 360° Non-Destructive Testing (NDT) Before Shipment Every load-bearing surface is inspected by non-destructive testing before leaving our factory, guaranteeing that the internal and external quality of every mill table fully complies with industry standards.
After years of development, Changcheng Cast Steel products are sold throughout China and exported to Europe, the United States, Germany and many other countries and regions.

1. Large-Scale In-House Casting Base Changcheng Machinery operates its own large-scale casting base, led by top industry experts in casting process management and technical development. The base offers complete services from raw castings to finished parts, as well as full solutions for critical components.
2. Double-Checked Quality for Long-Lasting Wear Parts We develop a tailored process plan for each customer's specific needs and strictly monitor every casting stage. Every product undergoes 360° non-destructive inspection before shipment, ensuring no defective product ever leaves the factory. Advanced technology and meticulous casting practices guarantee casting quality — as a result, the first maintenance interval of our major wear parts is typically 2–3 months longer than comparable products.
