Abstract
Apparatus and methods for replacing worn out liners in material classifying cyclones which include segmented inlet housing liners that are removable through the opened top thereof. In a first embodiment, a stacked array of the especially configured liners are supported on a lifting ring in the conical housing of the cyclone and lifting straps are used to extract the lifting ring and the liners. In a second embodiment, a special hoist is inserted into the liners and operated to clamp onto the liners and hold them in the stacked array and then the hoist and the attached liners are extracted. In either embodiment, the liners are extracted without removing the cyclone from its operating position and completely disassembling the cyclone. The extracted liners are moved to a work station for replacement as needed. Refurbished liner arrays are inserted into the cyclone by using the lifting ring or the special hoist.
