WORKING PRINCIPLE FOR RETARDED ADHESIVE MORTAR BY MEANS OF SCREW CONVEYING AND WRAPPING MACHINE |
|
| Abstract: | By using the theories of rheology, the model and equation of retarded adhesive mortar are built. On this basis, the screw conveying and wrapping principle is analysed by the application of screw mechanism and the cutting, mixing, conveying and extruding roles to which retarded mortar is subjected in screw are discussed. This paper provides guidance for further understanding of the screw conveying regulation,its designed structure and all running parameters. |
| Keywords: | retarded adhesive mortar flowing and deformed characteristics screw conveying and wrapping working principle |
