Kneading extruding and granulating equipment

Abstract

The invention relates to a kneading extrusion pelletizing apparatus, comprising an extrusion screw (10) arranged under the central part between two kneading stirring paddles; wherein, the axes of the kneading stirring paddles are parallel to the axis of the extrusion screw (10). The discharge end of the kneading extruder (2) is connected with a distributing valve (3) with a first discharge opening (9) and a second discharge opening (8), wherein the second discharge opening (8) is connected with a granulating apparatus. As kneading and extrusion are integrated into an organic whole, the unexpected physical and chemical performance changes of the mixed materials in the circulation process, after the mixed materials are discharged form the kneader, which can influence the later granulation or even cause interruption of the later operation, are avoided; the granulation productivity and product quality are improved.

Description

Kneading extrusion granulation equipment technical field The invention relates to a granulation equipment, in particular to a kneading extrusion granulation equipment. Background technique Existing granulation equipment, kneading equipment and extrusion equipment are generally independent of each other. In particular, the kneading equipment and the extrusion granulation equipment belong to the processing equipment of two adjacent processes in terms of technology, but because many technical problems cannot be solved before, they have been working independently. On the one hand, the turnover of transferring the kneaded semi-finished products to the extrusion granulation equipment reduces the production efficiency. On the other hand, and more importantly, some materials (mixed materials) have unexpected changes in physical and chemical properties during the turnover process after they are discharged from the kneader, which affects the normal progress of extrusion granulation...

AI Technical Summary

Problems solved by technology

In particular, the kneading equipment and the extrusion granulation equipment belong to the processing equipment of two adjacent processes in terms of technology, but because many technical problems cannot be solved before, they have been working independently

On the one hand, the turnover of transferring the semi-finished products after kneading processing to the extrusion granulation equipment reduces the production efficiency

On the other hand, and more importantly, some materials (mixed materials) have unexpected changes in physical and chemical properties during the turnover process after they are discharged from the kneader, which affects the normal progress of extrusion granulation in the later stage, and even Unable to continue the later process
