Dense medium preparation is the most efficient way of gravity concentration.The main
equipment hydrocyclone which is widely applied characterized with small volume, no moving
parts,large handling capacity,high separation efficiency. The requirements on abrasion
protection of main parts of cyclone like guiding cylinder of feeding,cone and underflow
is more and more higher. Meanwhile, the requirement on service life of equipment is
more and more higher for reducing maintainance frequency and increasing profits,
especially for the abrasion of cyclone, elbow, pipeline etc.
When cyclone is at work, the rotary motion of material generates great centrifugal force, the
inwall of cyclone is worn at high speed. For dense material, the abrasion of inner is extremely
worse under high impact by centrifugal force. One-piece alumina ceramic tube is used as wear resistant lining in cyclone for its high hardness, strength,
abrasion resistance and economic practicality.
