A ball or tube mill which includes at least one grinding compartment, support means for supporting the grinding compartment, drive means for eccentrically driving the grinding compartment and a plurality of inflatable bellows supporting the support means for oscillating movement. In a preferred form of the invention, the support means is supported on four spaced inflatable bellows inclined with respect to one another such that their central axes intersect at a cone apex above the center of the mill. Means may also be provided for adjusting the pressure within each of the bellows to thereby adjust the height of the bellows individually.

Vibratory ball or tube mill

The jacket material of welding rods is removed and processed for reuse, and the rods are cleaned and processed for reuse by delivering the jacketed rods to a ball mill, grinding the jackets from the rods within the ball mill by oscillating the jacketed rods in the environment of equally long cylindrical grinding bodies while holding the rods and the grinding bodies against axial movement and in generally parallel disposition with respect to one another. The detached jacket material is conveyed continuously from the grinding chamber and further comminuted, the transport of the ground material being supported by flowing a fluid through the grinding chamber. The fluid may be a gas or a liquid and may contain a chemical reacting agent for an after treatment. The fluid may advantageously be circulated, freed from the solid material transported thereby, regenerated and/or heated. Both neutral and chemically reacting fluids may be alternately employed, depending on the particular materials involved.

Apparatus for the release of the jacket material of rod-shaped carriers

A method of and means for safely releasably tensioning structural parts such as clamping members for mounting tube or ball mills and comprising drawing the clamping members toward one another by means of a tie rod bolt sufficiently to effect necessary clamping grip on the mill tube, and then disposing a spacer in clamped relation between the clamping members and further tightening the bolt to prevent loosening of the bolt while protecting the tube mill against excessive clamping stress.

Method of and means for safely releasably tensioning structural parts

A ball mill having a wall forming a hollow tubular grinding chamber therein with balls or rods within the chamber and means for driving the chamber in a vibratory grinding motion with a fixed body in the form of an elongate shaft within the chamber supported on a tubular wearing plate having a gap along one side and springing outwardly to support itself firmly within the grinding chamber and having arms extending between the wearing plate and the fixed shaft for supporting the shaft and a removable end for the grinding chamber so that the shaft and wearing plate can be removed for replacement from the grinding chamber.

Ball mill with energizing body on the wearing plate

A vibrating ball mill having a pair of vertically spaced horizontally disposed grinding chambers rigidly mounted as a unit in a vibrating support frame. Each grinding chamber is enclosed by an insulating sleeve and at the connecting joint between the outer wall of the grinding chamber and the supporting frame a supporting device is arranged which has good insulating characteristics and is able to appropriately transfer the accelerating forces from the supporting frame to the grinding chamber.
