Strand Cutting Plastic Recycling Granulation Machine

Strand Cutting Plastic Recycling Granulation Machine

Introduction:

The processing granulation is usually used in plastic compounding and recycling. Concerning the plastic compounding, it means that the mixing of two or more components in an extruder produce a new product. During compounding, the virgin resins will be shaped with certain desired character by adding ingredients. And the plastic with new character will be extruded and granulated into pellets for storage and further application. As for the plastic granulating line, the processed post-industry and post-customer plastic will be melted, extruded and granulated into pellets, which are convenient for storage and further application. In general, the crushed or shredder plastic flakes which have been washed and cleaned have bad feeding efficiency for extruding, so the plastic granulating line for recycling is necessary.

Process Description
The strand cutting pelletizing belongs to cold cutting granulation. It means that the polymer is extruded from the die head as strands and cut by pelletizer when the strands are cold into solid state. The strand cutting pelletizing can be applied for almost of the polymer granulating. Because of its pelletizing concept, the strand cutting granulating line has several advantages such as, low investment, easy operation and universal application.

Characters of the strand cutting granulating line
Because of the simple structure of the plastic granulating line, the equipment investment is lower in comparison to other pelletizing solutions such as water ring granulating line and under water granulating line. The low equipment price with relative high performance is a significant advantage.
The simple structure can also provide customer a easier maintenance operation and lower repair cost.
The concept for extrusion, cooling and pelletizing is relative numerous, the single screw granulating line can fit almost all kinds of polymer.
However, the potential of strand broke could influence the production capacity and require relatively more human resource for production.
The automation grad for the whole process is relatively lower than other granulating method.
