Problems solved by technology

[0005] During the processing of gypsum, grinding is often required. Traditional grinding equipment includes metal grinding bodies and ceramic grinding bodies. Ceramics are used more because of their higher temperature resistance and stability. However, traditional ceramic grinding bodies are not fine enough for grinding products. , the hardness is poor, and it is easy to break after long-term use. In view of the above problems, here we propose a preparation method of ceramic grinding bodies for gypsum grinding

Abstract

The invention discloses a preparation method of a ceramic grinding body for gypsum grinding. The preparation method comprises the following steps of a, selecting the powder, using BaO (barium oxide),TiC (titanium carbide), Mo2C (molybdenum carbide), ZrO2 (zirconium dioxide), Cr2C3 (Chromium carbide) and TaC (tantalum carbide) as the raw materials, preparing acetic acid with concentration of 80% to 90% as a solvent, pouring into the raw materials, mixing with the raw materials, fully impregnating for 3 to 6h, mixing, and controlling the time within 0.5h, so as to obtain a grinding medium; b, drying the raw materials in step a, mixing with coke, selecting spheres, and fully grinding, wherein the ratio of spheres to material is 3:5, the rotation speed of sphere grinding is 300 to 450rpm, andthe duration of sphere grinding is 30 to 48h; c, screening the mixture after sphere grinding, wherein the sieve hole is 50 to 150 meshes; d, putting the screened mixture into a die, and pressing intothe blank at the pressure of 350 to 550MPa; e, heating the fetched blank, cooling the heated and formed blank, cutting after cooling, grinding and polishing. The prepared grinding body has higher hardness and longer service life.

Description

technical field [0001] The invention relates to the technical field of ceramic processing, in particular to a method for preparing a ceramic grinding body for gypsum grinding. Background technique [0002] Gypsum is a monoclinic mineral, a hydrate whose main chemical composition is calcium sulfate (CaSO4). Gypsum is a versatile industrial and construction material. It can be used in cement retarder, gypsum building products, model making, medical food additive, sulfuric acid production, paper filler, paint filler, etc. The microporous structure and heating dehydration of gypsum and its products make it have excellent sound insulation, heat insulation and fireproof performance. [0003] Gypsum is a monoclinic crystal system with a high degree of cleavage and is easy to crack into thin flakes. Heat the plaster to [0004] At 100-200°C, part of the water of crystallization is lost, and hemihydrate gypsum can be obtained. It is an air-hardening gelling material with two for...
