METHOD AND APPARATUS FOR MIXING MATERIALS

摘要

Dry to pasty materials are mixed in a preferably cylindrical container with the aid of a mixing rotor which, like the container, has a horizontal axis and is eccentrically journaled in the container. The rotor cooperates with a mass-shifter device likewise rotatable about a horizontal axis for passing the material batchwise and intermittently to the mixing rotor. Each time, a portion of material located close to the peripheral wall of the container on one side of the rotor is moved by the mass-shifter device into the active mixing range of the rotor, the quantity of material thus mixed after each shifting action is piled up on top of the main heap of material located unilaterally in the container on the other side of the rotor.
