Abstract: A mixing device including a blade with radially outwardly extending arms and/or with a longitudinally extending wall with an elliptical cross-section. The elliptical cross-section may synergistically provide enhanced mixing and enhanced durability of the blade compared to previously known joint compound mixers. For example, the elliptical cross section may provide structural support to the radially outwardly extending arms and/or the longitudinally extending walls while allowing the radially outwardly extending arms and/or the longitudinally extending walls to cut through and spread joint compound. The structural support may allow the blade to be made of a plastic material. For example, the blade may be made of acrylonitrile butadiene styrene (ABS). Making the blade out of plastic may reduce scratching and degradation of the container that holds the joint compound during mixing, compared to previously known drywall mixers made of metal.

Abstract: A kneading apparatus has a pair of rotary shafts mounted to undergo rotation in different directions of rotation and at different rotational speeds from one another. Stirring members are helically arranged on outer peripheries of the rotary shafts at predetermined helical and angular pitches for kneading an object during rotation of the rotary shafts. The helical pitch of the stirring members of one of the rotary shafts has an inverse helix from that of the stirring members of the other rotary shaft. The stirring members have surfaces with a first phase configured to move the kneaded object in a feed direction or a second phase symmetrical to the first phase and configured to move the kneaded object in a direction reverse to the feed direction. The stirring members are arranged so that the first and second phases cyclically repeat in a predetermined sequence in axial directions of the rotary shafts.

Abstract: The present invention is related to a glass stirrer providing for improved stirring, reduced glass cord and easy adjustment of processing parameters during operation.

Abstract: The aim of the invention is to improve an existing mixing device in such a manner that for a predetermined reactor length, retention time is increased and the material which is to be processed is transported at essentially the same speed irrespective of the radial distance thereof from the rotational axis. As a result, at least one row of blades is arranged on each shaft and each row of blades comprises at least two individual blades and the blades are fixed to the shaft at an incidence angle ? in relation to the longitudinal axis of the shaft. The blades are curved in themselves, such that the blades form an angle of incidence ? at the fixing point on the shaft and an angle of incidence ? on the outer diameter DA.

Abstract: The present invention relates to an apparatus for carrying out chemical and physical processes, wherein flowable substances are mixed together, comprising a vertical, cylindrical vessel with inlets and outlets, as well as a central shaft and radial agitator blades arranged on the said central shaft and extending close to the wall. In this context, viewed in the peripheral direction, the agitator blades are curved and are combined in pairs of agitator elements one above the other to form groups, the blades of one element of the group being curved in a radially concave manner and the blades of the other element being curved in a radially convex manner.

Abstract: The invention relates to a method and to a device for homogenizing a glass melt in a melt receptacle, wherein at least one stirring device (10, 11) is disposed in the melt receptacle, which comprises a stirrer shaft (10) and a plurality of stirrer blades (11), and wherein a gap (16) is formed between a wall region of the melt receptacle (2) and the stirrer blades (11). According to the invention, the respective stirring device causes an axial feed action in an inner stirring region (12) between the stirrer shaft (10) and the stirrer blades (11) in order to feed the melt in the stirring region along the stirrer shaft (10). A melt flow brought about by the axial feed action seals the gap (16) against direct passage of the melt. According to the invention, a very high gap width can be achieved, thus preventing the abrasion of materials in the region of the marginal gap. This also reduces the complexity required for adjusting the device.

Abstract: A pin conveyor for pasty materials such as animal waste including a housing with a cylindrical inner surface extending along and about an axis. Within the housing surface, a shaft is mounted for rotation about the axis and has a plurality of pins attached to it in a substantially helical pattern. The pins have sleeve members slidably mounted about them wherein in operation, the sleeve members are centrifugally impelled outwardly of the pins to contact and scrape clean the housing surface as the shaft is rotated about the axis. The cylindrical outer surfaces of the sleeve members preferably overlap or are at least tangent to one another when viewed in a plane perpendicular to the rotational axis so as to effectively contact and scrape clean the entire housing surface surrounding them.

Abstract: A mixing and reducing machine with an upward-conveying mixing spiral that rotates around a vertical rotational axle.

In this way, zones of different axial conveying capacity are connected after each other in the axial direction. The mixing spirals are formed of several mixing blades arranged after each other in the circumferential direction.
