Stirrer grinder with grinding chamber

摘要

The grinder has a grinding chamber (42) containing agitator shaft (18) and with one or more screen bodies (34) between the shaft and agitator elements. Each screen body is mounted in a chamber extending towards the longitudinal axis of the shaft and defined by the shaft itself and by webs running axially parallel to the shaft forming a cage like rotor (36). When the shaft is stationary the screen bodies are removable through ports between the webs. The rotor can comprise a grinder disc (24) without webs and a grinder disc with webs. The two screen bodies arranged oppositely relative to each other can be connected by a pipe (38) to the material outlet (30).
