What Is a Plastic Agglomerator?
A plastic agglomerator machine is a cost-efficient way of recycling thin-walled polymers. It is easy to operate and saves labor.
Plastic agglomerator machines are used to physically transform loose plastic material into chips suitable for feeding into the hopper of an extruder.
An agglomerator consists of a cylinder with five to nine stationary blades and two rotating blades at the bottom that generate friction and heat. This process causes the material to reach its softening point.
At this stage, the operator adds a small amount of water to create a thermal shock. After the water evaporates, the material exits through the pneumatically operated discharge door in the form of chips.
Agglomerators can be used as material dryers and densifiers. Wanrooe manufactures agglomerators in various drum sizes, with capacities ranging from 100 kg/h to 1000 kg/h.
How Does an Agglomerator Work?
The plastic agglomerator is powered by a three-phase asynchronous motor and driven by V-belts. This drives the dynamic knife on the fastened dynamic knife plate, creating a rotating shear action with the fixed knife attached to the pot body.
The thermoplastic film placed into the pot body is repeatedly broken. At the same time, due to the high-speed rotation of the rotating knife disc, the broken plastic pieces form a vortex under centrifugal force.
The material becomes slightly plasticized by the frictional heat generated between the material and the pot wall. It is then cooled by the addition of water, causing the material to cool and agglomerate.
The plastic agglomerator is primarily used to pelletize low-bulk-density film fragments and also has a dense drying effect. The resulting particles can be easily transported after agglomeration.
Plastic Agglomerator Performance and Structure
1. The pot body is made of high-quality stainless steel welded construction, and the blades are made of special alloy tool steel.
2. The spindle is heat treated, straightened, and then finished by precision machining.
3. The agglomerator machine operates with low noise and delivers high output. The fixed knife uses a removable blade design, which is extremely convenient for use and maintenance.
