Problems solved by technology

[0002] In ceramics, cement and other industries, it is customary to use ball mills for grinding. In the past, steel balls or steel forgings were mostly used as grinding bodies. Due to the heavy weight of steel balls or steel forgings, ceramic grinding bodies are generally used instead of steel balls or steel forgings. Grinding, but the existing ceramic grinding body has poor wear resistance and needs to be replaced frequently to ensure normal production, and has poor impact resistance and is particularly easy to break. At the same time, the worn grinding body cannot be reused, resulting in serious waste

preparation example Construction

[0035] In a specific embodiment of the present invention, the preparation method of a ceramic grinding liner for cement powder, the pre-forming treatment includes the following steps:

[0036] 1) use high alumina bauxite for smelting;

[0037] 2) Add silicon oxide, carbon, manganese, chromium, boron nitride, zirconia, yttrium oxide, and phosphorus pentoxide into the furnace according to the above ratio;

[0038] 3) Raise the temperature in the furnace to 1550-1750°C at a rate of 80-90°C / h;

[0039] 4) After keeping warm for 40-60 minutes, raise the temperature to 1700°C-1800°C, then add deoxidizer to keep warm;

[0040] 5) After 50-60 minutes of heat preservation, the base liquid of the lining plate is obtained, and the vacuum operation is carried out during the heat preservation process to ensure that the negative pressure of 0.3-0.6KPa is maintained in the furnace;

[0041] 6) Add titanium alloy and aluminum oxide to the liner base liquid, and then keep it warm for 2 to 3 ...

Abstract

The invention provides a ceramic grinding lining plate for cement powder and a preparation method thereof. The ceramic grinding lining plate for cement powder comprises a titanium alloy, silicon oxide, carbon, manganese, chromium, aluminum oxide, boron nitride, zirconium oxide, yttrium oxide and phosphorus pentoxide with the component ratio being 35-40: 1-1.5: 2-3: 0.5-1: 0.5-1: 10-15: 35-40: 2-3:3-5: 1-2: 1-2. By replacing traditional Fe with the titanium alloy, the impact resistance and toughness of the grinding lining plate are effectively improved, the grinding lining plate is prevented from cracking due to excessive impact in the grinding process, the abrasion resistance of the grinding lining plate is improved, the grinding effect is better, and the service life of the grinding lining plate is effectively prolonged.

Description

technical field [0001] The invention relates to a grinding body for producing cement powder, in particular to a ceramic grinding liner for cement powder and a preparation method thereof. Background technique [0002] In ceramics, cement and other industries, it is customary to use ball mills for grinding. In the past, steel balls or steel forgings were mostly used as grinding bodies. Due to the heavy weight of steel balls or steel forgings, ceramic grinding bodies are generally used instead of steel balls or steel forgings. Grinding, but the existing ceramic grinding body has poor wear resistance and needs to be replaced frequently to ensure normal production, and has poor impact resistance and is particularly easy to break. At the same time, the worn grinding body cannot be reused, resulting in serious waste. Contents of the invention [0003] The invention proposes a ceramic grinding liner for cement powder and its preparation method. The traditional Fe is replaced by a ...
