High quality Alumina ceramic polishing balls

High quality Alumina ceramic polishing balls
Product Detailed
1.Alumina grinding/polishing ball 2.93% Al2O3 3.High density 4.large anti-compression strength

activated alumina/alumina ball/alumina powder/alumina ceramic/calcined alumina

1. Description of  Alumina:

Alumina ball is widely used in Ceramic industry,cement industry, paint industry, Color industry,

chemical industry,pharmaceutical industry, coating industry and mining industry. The advantages

are: high hardness, good toughness, high density,good erosion resistance, regular shape etc. 

Our alumina grinding is high grade milling media made by advanced cool isostatic pressing technology and fired at high temperature. 

Calcined alumina, aluminium oxied for making ceramic AI2O3 >99.5% Na2O <0.3% Fe2O3 <0.024% SiO2 <0.019% TiO2 <0.008% L. O. I <0.3% Density ≥ 3.93G/cm3 A-Al2O3 >93% Medium Particle Size(D50) 75um Ultimate Crystal Size 2-4um BET 0.5-0.6m2/g

4. Advantages

(1) Core Technology:

Using the global best alumina grinding ball production technology originated from our over 12

years working experience as well as our frequent technical research. This core technology

enable us to  produce high quality products continuously to satisfy the requirement of our

global partners.

(2) Production system&equipment:

we are using high temperature roller kiln (totally 2 kilns with each 250 meters length and

Max.1650 degree centigrade) to sinter the alumina ball, which enable us to producer higher

and more stable quality alumina ball due to the temperaturedifference of roller kiln is much

smaller than that of tunnel kiln used by other manufacturers. The prominent features of

alumina ball sintered by roller kiln are :

1) higher density  2) lower wear loss  3) more stability of quality 

(3) Supplying Capacity:

Due to the superior production system, we are manufacturing approximately 300 Ton medium and

 high alumina ball each day, which is considered to be 30% of the total global annual consumption

and enable us to deliver to our customer in shortest time as per requirement.
