Apparatus for mixing and/or kneading materials

An apparatus for mixing and/or kneading materials comprising:

• a housing defining a mixing and kneading chamber;
• a jacket member enclosing said mixing and kneading chamber and having a central axis;
• a mixing and kneading member located in the interior of said mixing and kneading chamber;
• means for driving said mixing and kneading member to a rotating and/or oscillating motion;
• means for supporting the mixing and/or kneading operation, said means comprising projection members protruding from said jacket member into the interior of said mixing and kneading chamber;
• at least some of said projection members being connected directly to said jacket member;
• said jacket member being connected to said housing member by means of connecting members distributed along the circumference of said jacket member, directed against said central axis of said jacket member and penetrating said housing in essentially radial direction with regard to said central axis of said jacket member.

A jacket member for an apparatus for mixing and/or kneading materials, said apparatus comprising:

• a housing defining a mixing and kneading chamber;
• said jacket member enclosing said mixing and kneading chamber and having a central axis;
• a mixing and kneading member located in the interior of said mixing and kneading chamber;
• means for driving said mixing and kneading member to a rotating and/or oscillating motion;
• means for supporting the mixing and/or kneading operation, said means comprising projection members protruding from said jacket member into the interior of said mixing and kneading chamber;
• at least some of said projection members being connected directly to said jacket member, said jacket member being made at least partially of ceramic material.
