Problems solved by technology

A major disadvantage of these processing methods is that only relatively simple geometries can be produced, which results in a characteristic shearing and shearing of the maximum shear rate at only one point or line between the moving kneading blades and the stationary kneading pins. Stretch flow zone, so that the corresponding energy is supplied to the sheared product dispersion

Embodiment Construction

[0019] now refer to figure 1 and figure 2 , a longitudinal sectional view and a sectional view of the schematically shown mixing kneader 1 are described here to help explain the mixing kneader involved. The mixing and kneading machine 1 includes: a working area 9 surrounded by a barrel 2, and the working area 9 is equipped with a rotating and translating working part 3. The working part 3 is provided with a kneading vane 4 which is configured as an annular thread to form an opening 5 through which the kneading pin 6 mounted on the barrel 2 can pass axially. according to figure 2 , it is clear that the barrel 2 preferably comprises two parts 2a, 2b provided with temperature control holes 7 . A liquid or gaseous medium circulates in the temperature control holes 7 to heat and / or cool the barrel or working area. The basic shape of one such mixing kneader is known, for example, from CH 278,575.

[0020] Furthermore, the mixer kneader 1 can feature one or more damping rings...

Abstract

The mixing and kneading machine ( 1 ) for compounding bulk-flowable, plastic and / or pasty masses comprises a working space ( 9 ) enclosed by a casing ( 2 ), and a working member ( 3 ) moving rotatingly and translationally in the casing ( 2 ). The working member ( 3 ) comprises a plurality of kneader vanes ( 4 ). Secured to the casing ( 2 ) are kneader pins ( 6 ) which protrude into the working space ( 9 ). To optimize processing, the main surfaces of the kneader vanes ( 4 ) and / or of the kneader pins ( 6 ) are configured at least in part as main surfaces ( 23 a- 23 f).

Description

technical field [0001] The invention relates to a mixing and kneading machine mainly used for mixing bulk flowable, plastic and / or pasty materials. For example, mixing and kneading machines can process viscoplastic substances, homogenize and plasticize plastics, mix fillers and reinforcing agents, and can also process raw materials for food, chemical / pharmaceutical and aluminum industries. The working part of the mixing kneader is usually shaped as a so-called screw, which advances the material to process the material axially. Background technique [0002] In a traditional mixing and kneading machine, the working parts only do rotary motion. Furthermore, the working parts of the known mixing and kneading machines can also perform both rotational and parallel movements. The motion profile of the working part is characterized specifically by the sinusoidal motion of the main shaft on the rotational motion. This movement profile makes it possible to assemble such fastening e...
