The alumina ceramic tube has excellent conductivity,high machinery
strength and high-temperature resistance, wear-resistance,
corrosion resistance, impact & brush resistance, smooth wall of
interior and exterior,airflow unobstructed,long service life and
reduced maintenance ,can resist to the acid,high
temperature,corridion and static electricity.
Mining classifying & concentrate cyclone,Coal separation &
classifying cyclone, Environmental protection cyclone
Wear resistant alumina ceramic tube are widely used in coal
preparation plant, coal-electing / sparating equipment and other
