Product Description
65-70% Al2O3 Alumina Grinding Ball For Fiber Cement
Introduction
Refractory ceramic balls are made from industrial alumina and other raw refractory materials, and processed by mixing, shaping and firing .It has properties of.Refractory ceramic balls can be used as support and covering packings for catalyst in shift converter, reformer, hydro converter, desulfurizer, and methanator, and can also be used as packings in hot blast heater and heat transformer in iron and steel industries.
Features
1) Spheres (balls) or cylinders
2) Very excellent support and covering media
3) Function as support media for catalyst beds or other chemical beds in reactors or towers
4) Very excellent performances and stability in acid and other chemical surroundings
5) Very good chemical stability and low rate of water absorption
6) Can withstand high pressure and high temperatures
7) Can be even used in hot caustic service because they can resist over 10% sodium hydroxide service up to 60ºC, and 1% sodium hydroxide service temperature up to 100ºC
8) Can also resist the chemical corrosions of any acid (including organic and inorganic acids, but except HF acid), most of alkali and organic solvent
9) Will increase the distributors of liquid and gas, supporting and protecting the catalyst and avoid poisoned
Application
(1)Used in high speed stirred grinding mills;
(2)Ball mills as abrasive media for ceramic raw materials;
(3)Glaze materials in ceramic factories, cement factories, enamel factories;
(4)Used in glass work, owing to the excellence of high density, high hardness,
and high wear rate. During the abrasive/grinding processing, ceramic balls will not
break up, they will not pollute the grinding material as well;
(5)The mix and crush procedure of ceramics, glass, glaze and frits, chemical and plastic industries.
