The alumina ceramic tube is a ideal wear-resistance material for delivering the sand,mine,ash dregs and molten aluminium ,has excellent conductivity,high machinery strength and high-temperature resistance,can resist to the acid,high temperature,corridion and static electricity.
Characteristics:
Good wear
resistant property and long service life
Smooth surface,
low friction coefficient, low density and light weight
Resistant to all
kinds of acid, alkali and salt
Hardness is only
second to diamond
Low thermal
expansion coefficient and thermal conductivity, operating
temperature can be up to ***0 °C
Alumina ceramic tube/lining
Various acid and high temperature resistant tiles and plates/sheets can be lined inside towers, pots, reactors, ponds, pond grounding and ditches for chemical industry, metallurgy industry and coal-fired power stations.
Wear-resistant linings can be used for the pneumatic conveying of powdered and grained materials, dust collection conveying and belt conveying where their good abrasion-resistant property will play important roles.
various hard materials. They are mainly used as lining materials of conveying equipment for materials like coal, cement and mining ores.
They are specially suitable for applications like coal conveying in power stations, slag conveying pipelines, material conveying for mines and docks, cement powder selecting equipment and crushing equipment for fine ceramic materials. They are featured as high wear-resistant and easy for installation.
