Abstract
A continuous kneader includes a screw shaft rotatable within a cylinder, and rotatable disks fixedly mounted on the shaft for rotation therewith. Stationary disks are arranged in face-to-face opposed relation to the rotatable disks. Each of the opposed surfaces of the disks is formed with alternating ridges and furrows. The material is passed between the opposed disk surfaces while being subjected alternately to compressive and shearing forces. Grooves are formed in the inner peripheral surface of the stationary disk and a screw section is carried on the adjacent outer peripheral surface of the drive shaft to promote the axial advance of the material through the device.
Claims8
A continuous kneader for plasticizable materials comprising in combination:
- a housing having a feed inlet adjacent one end thereof for introduction of the material to be processed and an outlet adjacent the other end thereof for the discharge of processed material;
- a drive shaft rotably mounted within said housing having screw means thereon for axially advancing the material towards the discharge end of said housing;
- at least one rotatable disc fixedly carried by said drive shaft for rotation therewith;
- a series of generally radially-extending alternating ridges and furroughs on at least one face of said rotatable disc;
- at least one stationary disc depending from said housing in concentric relation to said drive shaft and in face-to-face spaced relation with one of said rotatable discs, said stationary disc terminating peripherally at the free end thereof in spaced relation to said drive shaft, the face of said stationary disc disposed adjacent the ridged and furroughed one face of the rotatable disc being provided with a series of generally radially-extending alternating ridges and furroughs, the boundaries between the ridges and furroughs on said rotatable disc being angularly displaced relative to the boundaries between the ridges and furroughs of said stationary disc;
- said screw means on said drive shaft including a screw section adjacent the peripheral free end of said stationary disc;
- and at least one generally axially extending groove formed in the peripheral free end of each said stationary disc;
- whereby material fed to the inlet of the kneader is advanced sequentially between corresponding faces of rotatable and stationary discs and is subjected alternately to compressive and shearing forces as it is urged circumferentially and radially therebetween.
