Abstract

The invention discloses a preparation method of ceramic powder. The preparation method comprises the following steps: delivering raw materials to obtain pre-mixture; smashing and slurrying the pre-mixture to obtain slurry; carrying out sieving and deironing on the slurry; carrying out spray granulation on the slurry subjected to the sieving and deironing. The step of smashing and slurrying the pre-mixture to obtain slurry is characterized in that the pre-mixture is smashed by a ball mill, the percent contents of ballstones of different diameters in the ball mill are 30mm to 40mm to 50mm to 60mm=(5 to 20) to (25 to 35) to (30 to 50) to (5 to 20), the revolving speed of the ball mill is 10-15 rpm, and the ballstones used by ball milling are high-aluminum ballstones. The preparation method is characterized in that the ballstones of different diameters are mutually cooperated to smash the pre-mixture, meanwhile, the slurry is subjected to deironing by a deironing slot and an electromagnetic de-ironing separator, the preparation efficiency of the ceramic powder is improved, energy consumption is small, and efficiency is high.

Description

technical field [0001] The invention relates to the technical field of material processing, in particular to a preparation method of ceramic powder. Background technique [0002] At present, ceramic materials are a kind of inorganic non-metallic materials made of natural or synthetic compounds through shaping and high-temperature sintering. It has the advantages of high melting point, high hardness, high wear resistance and oxidation resistance. The existing preparation method of ceramic powder mainly consists of processes such as grinding, iron removal, homogenization, spray drying and powder making. The current preparation method mainly has the following defects: the quality of the intermediate product in the preparation process is not controlled, resulting in uneven quality of the intermediate product obtained in each step, which directly affects the processing efficiency of the next step, such as crushed slurry Too low or too high moisture and flow rate are not conduci...
