ZTA ceramic lining prolongs mechanical life, saves cost and improves material pu

Vertical mixing mill is a typical ultrafine grinding equipment, commonly used for silver ore, molybdenum ore, lead zinc ore, manganese ore, iron ore and nickel ore fine grinding or regrinding operations, but also for chemical materials grinding. During the grinding process, the inner cylinder of the mixer faces high temperature, corrosion, strong impact and intense friction, which leads to the inner cylinder of the mixer requiring frequent replacement and maintenance, which not only wastes manpower and material resources, increases costs, but also reduces the purity of the material and affects the quality of the product. ZTA ceramic lining effectively solves this problem.

Analysis of working condition of vertical mixing mill

1, high wear: In the process of grinding the material, the grinding ball and the material will rotate at high speed in the inner cylinder, resulting in intense friction on the inner cylinder wall. Moreover, many materials have very sharp edges and corners in the grinding process, and the cutting wear is serious, which will cause high wear in the inner cylinder of the mixing mill.

2, strong impact: the high-speed rotating mill ball and materials will constantly impact the inner cylinder of the mixing mill, causing a large load on the inner cylinder.

3, high temperature: high-speed rotating grinding ball and material and intense friction will produce high temperature, which is also the inner cylinder material selection, anti-wear need to focus on the problem.

4, acid and alkali corrosion: some chemical materials will have strong corrosion, metal and other chemically active materials are easy to be corroded, which can not work normally or affect product quality.

Wear, impact, corrosion will not only destroy the inner cylinder itself, but also the debris generated will reduce the purity of the material and affect the quality of the product.

ZTA ceramics are alumina zirconia composite ceramics. When used, the ZTA ceramic sheet is installed on the wall of the inner cylinder of the mixing mill by dovetail slot installation method to form an anti-wear layer. The anti-wear layer not only has the hardness of alumina, excellent anti-wear ability, but also has the toughness of zirconia, which can effectively resist impact, and the dovetail slot installation method is able to resist high temperature, and the chemical inertness of α-alumina makes it have strong corrosion resistance. Therefore, the vertical mixing mill ZTA ceramic inner cylinder can fit the mixing mill well. Customer feedback installed with ZTA ceramic mixing cylinder life of more than three years, the number of replacement maintenance is greatly reduced, saving costs, and ZTA ceramic basically does not produce grinding chips, but also conducive to improving the purity of the material.
