Example Embodiment

[0034] In order to make the objects, technical solutions and advantages of the present application, the present application will be further described in detail below with reference to the accompanying drawings.

[0035] First, further explanation of its application scenarios: The ball mill in the prior art is a relatively mature device. It is capable of satisfying the requirements of the material to meet the requirements of the particle size, but for zirconia ceramics, especially color Zirconia, the uniformity of its particle size is directly determined; the current ball mill does not reach the required accuracy, but it is difficult to achieve a balanced granular balance, resulting in the final product color difference, based on this reason, This application is proposed as follows.

[0036] The technical solutions provided in the present application will be described in detail in conjunction with the specific embodiments and drawings, and the accompanying drawings.

Abstract

The invention discloses a magnetic-attraction heavy-throwing type ball mill for preparing zirconium oxide powder and a lining thereof. The magnetic-attraction heavy-throwing type ball mill comprises a plurality of groups of lining plates, and the lining plates are spliced to form a cylindrical lining body; fixing rings used for keeping the combination state of the lining plates are arranged on the periphery of the formed lining body at equal intervals in the circumferential direction; and the cross section of each lining plate is of an arch structure with the middle protruding, so that the inner wall of a lining body formed by the lining plates forms a wavy surface, the formed ball mill adopts suction force generated by a magnet to increase the falling speed of a grinding ball, and therefore the ball mill has higher acceleration, larger impact force is generated to reduce the ball milling time, and the granularity of discharged material powder is balanced; and secondly, the magnet is arranged in the lining plate, and the magnet is arranged outside the ball mill to form magnetic constraint on the magnet in the lining plate, so that the magnet is always positioned at the bottommost part of the ball mill, and the horizontal projectile motion of the grinding ball cannot be influenced.

Description

technical field [0001] The invention relates to the field of zirconia grinding equipment, and more specifically, relates to a magnetic suction heavy-drop ball mill and an inner lining thereof for preparing zirconia powder. Background technique [0002] Zirconia is mainly used in high-strength structural ceramics. Many applications are based on the characteristics of high strength, high toughness, low thermal conductivity and high melting point of the material, such as refractory bricks, ceramic turning tools, grinding-free ceramic tools, grinding balls , Ceramic valves, molds, ceramic teeth, 5G mobile phone backplanes, etc.; therefore, zirconia is the cornerstone of modern ceramic technology buildings. [0003] In the production and use of high-end zirconia ceramics, the development of rare earth stabilized zirconia nano-powder coloring technology is very important, which is related to the quality of products and the realization of product functions. [0004] In the prepara...
