Abstract

A side feed type of roller mill having a housing, a rotating table provided in the housing, and a feed inlet chute extending obliquely downwardly through an upper side wall of the housing and having a lower end exposed over the rotating table. The feed inlet chute includes a cylindrical chute body and a liner mounted inside the chute body. The liner is formed of a flexible elastic material, so that the inner surface of the liner is irregularly deformed as accompanying peristalsis and vibration by both the own weight and the gliding/falling forces of a feed material passing through the chute and the elastic restoring force of the liner itself. Accordingly, a deposit layer of the feed material formed on the inner surface of the liner can soon be autonomously removed by the deformation of the liner without interruption of the operation of the roller mill. Thus, stable and efficient pulverization can be continuously performed.
