Abstract
A rotary drum pelletizer has multiple internal cone frustum baffles. The cone frustum baffles are interconnected serially to constitute a removable liner replaceably received within the drum and interchangeable with one or another of a series of such liners, each having different cone frustum baffle configurations. Means are provided to releasably fasten said liners to said drum. By interchanging one liner for another, the pelletizer drum can be adapted to process particulate material of widely varying characteristics to achieve desired pellet sizes, shapes and consistency.
