Detailed Product Description

As grinding media, high alumina grinding balls are widely used in the field of ceramics,
cement, painting, chemical industry, medicine and dope. They have the following
advantages: high hardness, high density, anti-corrosion, and regular appearance.
Specifications: 1) 70 series a) Alumina contain (%): 68 - 70; b) Water absorption (%): ≤0.02; c) Bulk density (g/cm³): ≥2.9 d) Mosh Hardness: 8 - 8.5 e) Color: white2) 80 series: a) Alumina contain (%): ≥85 b) Water absorption(%): ≤0.02 c) Bulk density (g/cm³): ≥3.4 d) Mosh hardness: 9 e) Color: white3) 92 series: a) Alumina contain (%): 92 b) Water absorption (%): ≤0.02; c) Bulk density (g/cm³): ≥3.5 d) Mosh hardness: 9 e) Color: white4) 95 series a) Alumina contain (%): ≥95 b) Water absorption(%): ≤0.02 c) Bulk density (g/cm³): ≥3.6 d) Mosh hardness: 9 e) Color: whiteCatalyst bed supportsAlumina support (inert alumina ceramic ball) is widely used in many fields, such
as petroleum, chemical engineering, fertilizer, smelting, medical treatment and
environmental protection. Being the covering and supporting material and tower packing
for catalyst in the reactor, ceramic ball has the feature of high temperature
and pressure resistance, low water absorption, and stable chemical performance.
It can not only resist the corrosion from the acid, alkali and other organic
solvents, but also the temperature change in production process. The main role
of ceramic ball is to increase the distributing spot of gas or liquid, also support
and protect the activated catalyst with low strength.
Alumina balls are available in following sizes:1) Nominal sizes: 3, 6, 13, 19, 25, 38, 50 2) Bulk density range (kg/L): 1.6 to 2.5 3) Apparent porosity range (%): 1 to 20 4) Crushing strength range (kg): 50 to 1,600
