Problems solved by technology

[0003] The preparation of ceramic powder has always been an important link in the production of qualified ceramics. The manufacturing efficiency and quality of ceramic powder will directly affect the production quality and production efficiency of ceramic products. In the traditional production of ceramic powder, its production process is very simple, but The production time is long, the production efficiency is low, the pollution is very serious, and the energy consumption is high, which is not conducive to the control of production cost

Embodiment Construction

[0015] Below in conjunction with specific embodiment the present invention is described in further detail:

[0016] In order to achieve the above object, the technical solution adopted in the present invention is: a kind of ultrafine ceramic powder ball milling process, comprising the following steps:

[0017] A. Put the ceramic powder, water and primary grinding balls into the first ball milling tank in proportion, and the first ball milling tank mixes the added ceramic powder, water and primary grinding balls, and the primary grinding balls are stirring During the mixing process, the ceramic powder is crushed once to an intermediate fineness.

[0018] B. After the ball mill tank stirs the feed liquid for a certain period of time, the ceramic powder in the slurry is ground to an intermediate fineness, that is, the slurry is extracted, and the primary grinding balls in the slurry are filtered at the same time, and the filtered slurry is put into In the second stage of the bal...

Abstract

The invention discloses a ball-milling process for superfine ceramic powder. The ball-milling process comprises the following steps of proportionally feeding ceramic powder, water and primary grinding ball stones into a first section of ball-milling tank, mixing the added ceramic powder, water and primary grinding ball stones with stirring by virtue of the first section of ball-milling tank, and performing primary medium-fineness crushing on the ceramic powder in a stirring mixing process by virtue of the primary grinding ball stones; pumping slurry out after the feed liquid is stirred for a long time by the ball-milling tank and the ceramic powder in the slurry is ground to medium fineness, simultaneously filtering the primary grinding ball stones in the slurry, and feeding the filtered slurry into a second section of ball-milling tank; adding secondary grinding ball stones into a second section of ball-milling tank according to a certain proportion, stirring the slurry within a preset time, and secondarily and finely grinding the ceramic powder in the slurry by virtue of the secondary grinding ball stones in the second section of ball-milling tank until final fineness is achieved.

Description

technical field [0001] The invention relates to a ceramic grinding process, in particular to an ultrafine ceramic powder ball milling process. Background technique [0002] With the development of society and the advancement of science and technology, the performance requirements of materials in industry and production are also constantly improving. Nowadays, it is difficult for a single material to meet the comprehensive requirements for its performance. The compounding of materials is one of the inevitable trends in material development. one. The excellent properties of ceramics such as high strength, high hardness, high elastic modulus, and thermochemical stability make it one of the hot composite materials studied by many scholars, but the inherent brittleness of ceramics limits its application range and reliability. . Therefore, improving the room temperature toughness and fracture toughness of ceramics and improving their reliability in practical applications has alw...
