I’m looking for recommendations for manufacturers of grinding media used in slurry thickening units; thank you!
Thread Content
1. Name of the grinding medium: Neutral ceramic microspheres. Specifications: φ1.0～1.5 mm, φ1.5～2.0 mm, φ2.0～2.5 mm, φ4.0～5.0 mm, φ5.0～6.0 mm. 2. Main chemical components: Al2O3: 42%～48%, SiO2: 39%～45%, ZrO2: 2%～8%； 3. True specific gravity: 2.75±0.05 g/cm3; Vickers hardness (Hv): 750; Mohs hardness: grade 8; compressive strength: 165 N (φ2 mm). 4. Ball diameter tolerance: ±0.30 mm ； 5. Whiteness: ≥93 ； 6. The surface is smooth and round, without any spots, color variations, cracks, melting holes, over-burning, or under-burning defects.
The thing the original poster is talking about is not often encountered in gasification; maybe I’m just uninformed – I really have never heard of it before, and I’m waiting for those who know more to give me some details.
I guess any enterprise that produces ceramic balls in Pingxiang can do this
