Mother Baby Plastic Recycling Machine (for Recycling and Pelletizing) :

Plastics granules making machine which works on a principal of plastic extrusion process, is a normally high volume manufacturing process where a polymer material, enriched with the desired additives, is melted and formed in a continuous process. Where output can get form of granules, tubes, sheets, lumps and etc. Double stage plastic recycling machine helps for better quality with high performance while maintaining the ratio of extruders. Helps to remove complete moisture and twice filtration.

How It Works :

In the entire process, A plastic material, normally in flakes form is placed into hopper of mother extruder, usually made from fabricated from mild steel or fabricated from stainless steel as per material requirement. There is a hopper magnet fitted inside the hopper to stop metallic particles from entering inside the barrel. The raw material in the form of flakes, is gravity fed into the hopper and through the feed throat, drop on the rotating screw. Barrel has several amount of heaters fitted on the outer diameter. Which heats up the barrel to get extrusion process job done. Screw is connected with helical gearbox and AC motor which helps to rotate the screw of mother and baby extruders. Raw material in flakes form starts to move forward along the rotating screw and enters the heating spot of barrel. Where it starts to melt. Molten plastic reaches the end of the barrel where hydraulic screen changer is fitted which filters the molten plastic and converts it into plastic lumps out of unique design die which helps to remove all possible moisture contained in lumps. Plastic lumps then drops into baby extruders hopper. Baby extruder also does extrusion process and molten plastic moves forward, reach to the second screen changer. Where screen changer filters the plastic and converts it into plastic strands. Strands moves forward and drops inside the stainless steel water tank and its temperature starts to cool down. Plastic strands then enters the pelletizer machine which turn it into pellets.

Model Range :

various models available which are classified according their production rate. 90 mm to 130 mm screw size extruder models available.

Production range :

Production Range of 100 kg/hr to 500 kg/hr.
