A bar extends in the axial direction and is rotationally fixed to the rotor, and a limiting element fixed with respect to the mixing tank cooperates with the bar, with the limiting element being configured such that the bar rotates with respect to the limiting element and with a tilt of the rotor being limited by a physical contact between the bar and the limiting element.

A method for handling a product, in particular a viscous, pasty product, with at least one rotating shaft (3, 11) in a product space (5), a driving spindle (11) of the shaft (3) is mounted and sealed outside the product space (5) in a housing consisting of a plurality of parts (7, 8, 12). The sealing is brought about by at least two seals (2, 4), wherein a dynamic seal (2) follows an eccentric movement of the shaft (3) and takes on dynamic sealing of the rotating shaft (3), while another seal (4) compensates for an eccentric movement of the shaft (3) in relation to the housing by plastic or elastic deformation and therefore prevents a leakage between the housing part (12), which moves eccentrically, and a rigid housing (10). A defined quantity of liquid, which serves as a blocking agent and lubricant for the dynamic seal (2) of the shaft (3) towards the housing part (7), is metered in here, the liquid, apart from a residual excess, being drawn into the dynamic seal (2) by a pressure difference therewithin and thereby forming an effective block and seal.

A mini mixer system includes a mixer, for executing a continuous mixing operation for an extended period of time, the mixing operation includes a mixing production process with corrosiveness, high viscosity and high mixing risks. The mixer includes a motor, a coupling and torsion meter, a reduction gear, a plurality of couplings, a frame group, a gear box group, at least one mixing element, a mixing can and a lifting mechanism group. The motor, the coupling and torsion meter and the reduction gear are connected to one another by the couplings. The reduction gear is connected to the gear box group by the coupling. The motor, the reduction gear, the gear box group and the lifting mechanism group are all fixed on the frame group. The mixer is assembled in a gear mechanism of the gear box group. The mixing can is disposed on the lifting mechanism group.

A system for mixing content of a container comprises a container includes an interior mixing element, an exterior drive system and a mixing device comprising an exterior bearing for coupling the exterior drive system to the interior mixing element of the container. The exterior bearing provides a driven non-rotating, nutating motion that drives the interior mixing element of the container so that it performs a mixing motion inside the container.

A stirrer (1; 100) for stabilizing liquid binding unfinished products intended to form ceramic items comprising a support shaft (2) individuating a longitudinal rotation axis (Y) and contained into a mixing tank (V) of the liquid binding unfinished product, motorization means (3) operatively connected with the support shaft (2) in order to rotate it around the longitudinal axis (Y), and a main operating blade (4), coupled with the support shaft (2) through interconnection means (5) in such a way as to be contained into the mixing tank (V) in order to interfere with the liquid binding unfinished product and cause its continuous mechanical mixing action inside the mixing tank (V) itself when the support shaft (2) rotates around the longitudinal axis (Y). In this case, the stirrer (1) includes a thermoregulation circuit (6), which extends within the support shaft (2) and within the main operating blade (4) and is connected with an external source for supplying a heat transfer fluid crossing the thermoregulation circuit (6) in such a way as to exchange heat with the liquid binding unfinished product within the mixing tank (V), in order to bring the it to a predefined temperature, while the support shaft (2) and the main operating blade (4) integral with it rotate around the longitudinal axis (Y).
