Agglomeration machines are a cost-effective approach to recycle polymers with thin walls. Agglomeration machines are used to physically convert free plastic into chips that can be fed into an extruder’s hopper. An agglomerator is a cylinder with five to nine stationary blades at the bottom and two moving blades that create friction and heat. The material reaches the softening point as a result of this process. At this point, the operator adds some water to generate a shock effect. After the water evaporates, the material is discharged as chips through a pneumatically driven discharge door. Agglomerators can be used to dry and densify materials.
