Abstract
Cyclone separator apparatus and method of manufacture are described for providing a separator cone of abrasion resistant material covered by a sleeve of plastic material having flexible seal regions at least some of which are spaced from the outer surface of the cone. The cover sleeve of plastic is bonded to the cone of abrasion resistant material which is preferably made of aluminum oxide ceramic material, by heating the cone to a temperature above the melting temperature of the plastic, inserting the heated cone into the sleeve to melt the inner surface of the sleeve and cooling the assembly below such melting temperature to bond the sleeve to the cone. The sleeve may be made of polyethylene or other suitable thermoplastic or thermosetting plastic materials and the cleaner cone can be made of ceramic material, metal or other suitable abrasion resistant materials of high melting temperature than the plastic sleeve. As a result of the flexible seal regions formed by circular ridge projections on the outer surface of the plastic sleeve, the cyclone cleaner cone can be inserted through three mounting apertures in the walls of pressure chambers and sealed to wall flanges surrounding t…
