摘要:
The invention relates to a method and device for preparing a paste by means of blending or mixing materials, in particular for making aluminum production electrodes. The method includes the following operations: a) introducing the materials to be blended or mixed into a vat (31) having an inner surface extending along a substantially horizontal axis of revolution (X), b) rotating the vat (31) about the axis of revolution (X) and urging the materials via centrifugation against the inner surface of the vat (31), and c) locally dislodging the centrifuged materials from the inner surface by rotating the vat (31) and causing same to fall onto a crumbling tool (40).

A concrete mixer comprising a main frame (11), a large bearing ring (18) carried by the main frame, the ring supporting an outer barrel carrier (15) for rotation, an inner rotary barrel (13) of elastomeric material supported for rotation by said barrel carrier (15), the barrel carrier (15) having a number of spaced fingers (14) extending away from the ring (18), there being a flexible strap (16) extending from each finger (14) to the outer surface of the barrel (13), so supporting the barrel that its wall can be deflected from the outside to dislodge concrete which might adhere to the inner surface, and an elastomeric rotor (27) supported for rotation within the inner rotary barrel.

A vibratory apparatus (10) and method for agglomerating chopped bundles of wet fiberglass strands into uniform segments includes a container (12) having a curved inner surface (14) disposed about a generally horizontal axis where the container (12) is mounted on a plurality of springs (20,22,24). The chopped bundles of wet fibreglass strands to be agglomerated are placed onto the curved inner surface at an input end of the container (12). A vibratory force is produced to cause the chopped bundles of wet fiberglass strands to be moved from the input end toward an output end of the container (12). The vibratory force causes the chopped bundles of wet fibreglass strands to be directed in a rising and falling path of rolling movement within the container (12). As a result of the rolling movement of the chopped bundles within the container (12) which is produced by the vibratory force, the copped bundles of wet fibreglass strands are converted into uniform segments by reason of agglomeration of the wet fiberglass strands.

A method and apparatus for coating granules of plastics material with a mixture of sand and salt grains comprises tumbling and heating a mixture of grains and plastics granules by passing them along a heated rotating hollow tube (1). The mixture of grains and plastics material granules are heated to a temperature not less than the softening temperature of the plastics granules so that the plastics granules become coated with the grains. The coated granules are then tumbled and cooled before leaving the rotating hollow tube.
摘要:
A process and device for producing co-extruded foam composites having any patterns in their mass. The foam composites are taken together from at least two foamable polymer melt streams with different physical and/or chemical properties to an extruding tool after the application of a gas, at least partially mixed and/or twisted and then co-extruded.

An inline mixer to be fitted on the way of a pipeline (4) to stir up and mix the fluid flowing through the pipeline (4). The inline mixer is provided with a rotary cylinder (5) and a mixing element such as a static mixer (16) prepared within the rotary cylinder. The rotary cylinder is made of conductor material and an electro-magnetic coil (18), which generates rotary movable magnetic field, is located adjacent the rotary cylinder. This rotary cylinder is rotated by an electro-magnetic inductive action due to the electro-magnetic coil.
