Abstract
Disclosed is a closed type mixing and kneading apparatus with two juxtaposed double-wing rotors providing increased mixing and increased shearing action. One of the wings of each rotor has a length ratio of 0.6 to 0.9 relative to the total length of the rotor at a twist angle of 10.degree. to 40.degree.. The two wings of each rotor are overlapped by between 0.2 and 0.8 times the total length of the rotor.
Claims6
A closed type mixing and kneading apparatus having within a mixing chamber a pair of juxtaposed double-wing rotors defining an intercommunicating portion of said chamber therebetween, each one of said rotors having the respective wings thereof twisted to move a charged material inward from one end of said mixing chamber, one of the wings of each rotor having a length ratio of 0.6-0.9 relative to the total length of said rotor and a twist angle of 10.degree.14 40.degree., said two wings being overlapped by 0.2-0.8 of the total length of said rotor, whereby increased mixing or shearing action is produced in said intercommunicating joint portion.
A closed type mixing and kneading apparatus having within a mixing chamber a pair of juxtaposed double-wing rotors defining an intercommunicating portion of said chamber therebetween, each of said rotors having the respective wings thereof twisted to move a charged material inward from one end of said mixing chamber, said wings of each rotor satisfying the following conditions:
- ##EQU10## in which l1, l2:
- axial lengths of the two wings
- L:
- length of the rotors
- .theta..sub. :
- twist angle of the wings
- Ho:
- clearance between the rotor body and barrel
- .alpha.:
- ratio of the length of an open wing portion to L
- Bo:
- volume of the mixing chamber
- BF:
- stowage of the material
- D:
