摘要：
Solids conveying is the least understood operation for single-screw, plasticating extruders, yet it can be the source of many problems such as flow surging, low rates, high discharge temperatures, and material degradation. A lack of solids conveying devices and adequate physical property data for resins has contributed to this poor understanding of the section. For this paper, experimental solids conveying rate data will be presented for a low density polyethylene (LDPE) resin at several different process conditions for two screws with either a smooth or grooved barrel.
