Grinding mills

A stirring device for stirring a particulate material and a grinding media in a grinding mill includes one or more protective elements that extend outwardly from a body to deflect the particulate material and the grinding media from the body to minimize contact of the mixture of the particulate material and the grinding media against the body and to promote contact between the particulate material and the grinding media.

A stirred bead grinding mill includes a substantially cylindrical grinding shell and a central stirring shaft within the grinding shell. The central stirring shaft is provided with axially spaced stirring elements, preferably grinding discs, along the central stirring shaft. A replaceable grinding element is provided that includes an axial support structure arranged to form the outer periphery of the grinding element adapted to fit within the grinding shell, and at least one counter disc arranged to project radially inward from the axial support structure to an extent separating two grinding zones in an axial direction while allowing the central stirring shaft within the grinding shell, wherein at least part of the counter disc and/or the support structure is provided with castellations.
