Product Details

95% Zirconia Ceramic Ball Mill Grinding

 

Description

 

Zirconia Ceramic Ball

 

Appearance: With pearl-like luster and smooth working spherical surface, it is the best in grinding media

 

Purpose: Especially suitable for vertical mixing mill, horizontal rolling ball mill, vibration mill and various high-speed pin sand mills, etc.;

Wet and dry ultrafine dispersion and grinding of various slurry and powders that require refusal of cross-contamination. The application areas as follows:

1. Wear-resistant and corrosion-resistant products: coatings, textiles, pigments, printing and dyeing

2. High-strength, high-toughness products: magnetic materials, piezoelectric ceramics, dielectric ceramics

3. Prevent pollution: medicine, food, cosmetics

4. Ceramics: electronic ceramics, refractory ceramics, structural ceramics

 

Features: High strength and toughness, high density, good wear resistance, high temperature and corrosion resistance, high rigidity, high toughness at room temperature

Magnetic conductivity, electrical insulation, thermal expansion coefficient close to steel and other advantages. The strength and hardness of the zirconia ceramic ball at 600℃

Almost unchanged. Using yttrium oxide as a stabilizer, it is made by a special molding process and a high-temperature firing and phasing process.

1. High grinding efficiency: the specific gravity of yttrium stabilized TZP zirconia ceramic beads is 1.6 times that of ordinary zirconia beads, under the same conditions

Has a higher grinding efficiency.

2. Good fluidity: The product has good roundness and smooth surface, and the wear on the equipment is lower than other grinding media.

3. Impact resistance and low abrasion: TZP zirconia ceramic beads have good toughness and will not crack or open in high-speed, high-concentration machines

Peeling and abrasion are only 2/1 of the zirconium silicate beads.

4. Low cost of use: Choosing this product will definitely bring you a reduction in comprehensive costs such as media wear, power consumption, labor, and equipment, and greatly improve product quality.
