橡胶冷喂料挤出机加料段浅析

Analysis of the Feeding Part of Cold Rubber Feeding Extruder

通过对粉状或粒状塑料和带状橡胶条在加料段运动的对比分析,指出固体输送理论及其数学模型不能用于指导橡胶的挤出。同时指出加料段机筒纵向开槽不会提高橡胶的输送效率,而在其上设置销钉则会达到这一目的。

By analyzing the powdered or granular plastics and rubber strip which move in the feed part of an extruder, it is known that the solid conveying theory and its math model cannot be used to instruct the rubber extruding. Meanwhile, it is impossible to improve the rubber conveying efficiency by opening lsots inside the feeding barrel. But the objective can be easily reached if installing pins in the inner surface of the feeding barrel.
