Alumina Ceramic Sleeve Application
By cold isostatic pressing process, alumina ceramic sleeves have the advantages of high hardness and abrasion resistance,defined and uniformly low erosion,dimensional stability and low specific weight.
Yiho manufactures alumina ceramic rings with the single bevel or double bevel, assembled into a set of ceramic lined elbow.
Yiho provides both standard and customize alumina ceramic lined pipe and elbow.
Alumina ceramic cylinder / lining tube / sleeve lining with high abrasion resistance are widely used for serious abrasive environments, such as chute liners, cyclone liners, conveyor skirt liners, processing piping liners, hopper or silo liners, screen equipment liners in the industries including ,but not limited to:
♦ Coal Preparation Plants ♦ Coal Fired Power Stations
♦ Mineral Processing Plants ♦ Cement Plants
♦ Chemical Plants ♦ Steel & Iron Plants
♦ Railway Stations ♦ Ports
Alumina Ceramic Sleeve Properties
High density, high hardness, low wear loss, regular shape, impact resistance, corrosion resistance, etc.

Alumina Ceramic Sleeve Advantages & Application
The Alumina Sleeves are often used in machines and systems of steel plants, foundries, mining, processing and preparation of minerals, within the paper, pulp, chemical and lithium battery industries, in power plants (coal, wood and solid fuels), in cement production, and in concrete production and transportation.
Compare to traditional stone, ceramic lined pipe has the advantages of high hardness and abrasion resistance,defined and uniformly low erosion,dimensional stability and low specific weight.
