Bulk kneader reactor producing melts from mixed, contaminated recycled plastics

The kneader-reactor produces melts from used plastic and plastic mixtures. The melts form raw materials or are further processed. The unit contains two heated agitator shafts (3) fitted with inter-engaging kneader sections (2). These rotate at different speeds; their ratios ranging from 1:2-1:4. Cle...

Zusammenfassung:	The kneader-reactor produces melts from used plastic and plastic mixtures. The melts form raw materials or are further processed. The unit contains two heated agitator shafts (3) fitted with inter-engaging kneader sections (2). These rotate at different speeds; their ratios ranging from 1:2-1:4. Clearance between kneaders and shafts or casing inner walls reduces in the direction of material flow.
