Alumina Ceramic Lining
Products Introduction
Alumina Ceramic Lining are made with high alumina under 1500 degree
temperature firing in kiln. It has high compression strength, low
wear resistance and high hardness. There are all kinds of shape,
such as square, rectangle, sleeve,cylinder and some special shape.
Alumina Ceramic Lining is one of the most stable chemical
properties and the highest mechanical strength among refractory
oxides; Alumina ceramic does not react with most molten metals,
only Mg, Ca, Zr and Ti could have a reducing effect on it above a
certain temperature; hot Sulfuric acid can dissolve alumina, and
hot HCl and HF also have some corrosive effect on it; the vapor
pressure and decomposition pressure of alumina ceramics are the
smallest.
Wear resistant alumina ceramic linings is good liner for mineral
equipment, can be used in cyclone, pipe, bend, discharge,ball mill,
etc. Including 92%, 95% and ZTA series products.
HUAO's wear resistant alumina ceramic tiles can be cut into any
shape and are easy to install and maintain. They are suitable for
both wet and dry processing applications. Advanced ceramics combine
high strength and toughness with extreme hardness to deliver
exceptional wear resistance.

· What are the benefits of alumina ceramic lining?
Alumina ceramic lining provides many benefits, including:
- Increased wear resistance
- Improved corrosion resistance
- Reduced downtime and maintenance costs
- Longer equipment lifespan
- Enhanced productivity and efficiency
· What types of equipment can be lined with alumina ceramic?
Alumina ceramic lining can be applied to a wide range of equipment,
including:
- Pipes and fittings
- Cyclones and separators
- Ball mills and agitators
- Chutes and hoppers
- Fans and blowers
- Dust collectors and scrubbers
· How is alumina ceramic lining applied?
Alumina ceramic lining is typically applied using a bonding
material, such as epoxy or a ceramic adhesive. The ceramic lining
is carefully cut to fit the equipment surface and then bonded in
place. The surface may need to be prepared with a primer or surface
roughening for optimal adhesion.
