The invention discloses a method for manufacturing a wear-resistant ceramic roller lining plate, which comprises the steps of ball-milling and mixing 30-40wt% of aluminum trioxide, 10-20 wt% of kaolin, 10-25wt% of alumina, 20-35wt% of quartz powder, 5-10wt% of feldspar powder and 1-3wt% of zirconium oxide according to a proportion to obtain a base material, adding 1-3wt% of carboxymethyl cellulose and 2-5 wt% of Guangdong black mud into the base material, carrying out ball-milling and stirring uniformly to obtain clinker, spraying reinforcing materials accounting for 1-3wt% of the base material into the clinker under the air pressure of 0.3-0.5MPa, carrying out ball-milling, mixing and stirring to obtain powdery materials, carrying out extrusion molding on the powdery materials to obtain a lining plate blank, drying, firing, cooling and discharging from a furnace. It improves the elastic modulus and fracture toughness of the base material crystal grains, so that the lining plate not only has high compression strength and bending strength and high acid and alkali corrosion resistance, but also has better fracture toughness and impact resistance. |
