Factory Price 3-50mm 92/95/99% Al2O3 High Ceramic Mill Ball for Dry and Wet Grinding

Product Description

High alumina ceramic balls are ceramic materials with specific structures made mainly from high-quality alumina (Al2O3) through processes such as batching, grinding, powder production, molding and high-temperature calcination.

Its core feature is determined by its high alumina content, usually above 90%, with common grades including 92%, 95%, 99%, etc.

High hardness&high wear resistance: The Mohs hardness can reach level 9 (diamond level 10), which is very wear-resistant and has a long service life.

High mechanical strength: With high compressive strength, it can withstand tremendous impact and pressure without breaking.

Good chemical stability: acid resistant, alkali resistant, corrosion-resistant, and does not react with most chemical substances.

Good thermal stability: high temperature resistance, low coefficient of thermal expansion, able to withstand rapid temperature changes.

Good insulation: It is a good electrical insulation material.

Petrochemical industry: widely used in reactors of hydrogenation refining, catalytic reforming, cracking and other units.

Coal chemical industry: used for reactors such as synthesis gas purification and me-thanol synthesis.

Environmental protection industry: used as packing or support layer in waste gas and wastewater treatment towers.

Fertilizer industry: in the synthesis of am-monia, urea and other equipment.
