Definition / Mother Baby Plastic Recycling Machine / Double Stage Plastic Recycling Machine

Plastics Recycling Machine works on a principal of plastic extrusion process. is a normally high volume production process where a plastic polymer material, enriched with the desired additives, melted and formed in a continuous process. Where output can get in form of granules. Double stage plastic recycling machine is used for better quality output with high performance / high production rate while maintaining the ratio of barrels. Best to remove moisture completely and quality product due to twice filtration.

Application / Suitability :

For recycling purpose of plastic wastes which contains high moisture, heavy printings and heavy contamination.

best to recycle low density film waste without agglomeration process.

Material Suitability : All kind of plastic waste

How It Works :

In the process, A plastic material would be in plastic flakes form is inserted into extruder’s hopper, usually fabricated from mild steel or stainless steel as per material requirement. Hopper magnet fitted inside the hopper to resist metallic particles from entering inside the barrel. Raw material in the state of plastic flakes, is gravity fed into the hopper and reaches the rotating screw. Barrel has several nos of heaters fitted on the outer diameter. Which heats up the barrel to help the extrusion process to be done. Screw is fitted with helical gearbox and AC motor which rotates the screw. Raw material in flakes form initials to move further along the rotating screw and enters the heating spot of barrel, Where it starts to melt. Molten plastic reaches the end side of the barrel where hydraulic screen changer is fitted which filters the molten plastic and converts it into plastic lumps. Plastic lumps drops into baby extruder’s hopper. Baby extruder also does extrusion process and carry forward molten plastic towards second screen changer. Where second screen changer filters the molten plastic and converts it into plastic threads. Plastic threads moves forward and goes through the air knife. air knife removes the water from the surface of plastic threads and leads it to the stainless steel water tank. plastic threads drops in stainless steel water tank where temperature of plastic thread starts to drop. Plastic threads then enters the pelletizer machine which turn it into pellets.

Range Of Models & Production Capacity :

Different types of models available, which are classified according production capacities,

MRM/90/MB/EXT : Production 100-150 kg per hour
MRM/100/MB/EXT : Production 150-200 kg per hour
MRM/110/MB/EXT : Production 250-300 kg per hour
MRM/120/MB/EXT : Production 350-400 kg per hour
MRM/125/MB/EXT : Production 450-500 kg per hour

Models for production more than 500 kg per hour also available.

Important Features:

Screw/barrel made of EN41-B mild steel material, nitrided and honing finished for quality production and longer durable life span.
Optional : Tungsten carbide coated screw/barrel available, for high production machines to provide a longer and durable life span.
Screw designed for reprocessing, recycling and coloring application of plastic materials like LLDPE, HDPE, LDPE, PP, HM, ABS & HIPS.
Screws are specially designed for specific material to get better production quality.
Heating zones are divided on both barrel for accurate temperature control.
Digital pyrocontrol panel for faster heating and easy operating.
Thermocouples wires provided for each heating zone to control temperature with help of digital temperature controllers.
For both extruders, Movable motor attachment provided for extruder’s AC motor and pelletizer motor to adjust motors as per belts length.
Both Extruder’s fabrication is consisting of heavy and sturdy mild steel channel frame and covered with CRC sheets.
High efficient hopper magnet provided to detect and restrict the metallic particles from the polymer.
Screw is rotated by suitable AC motor with suitable heavy duty helical gear box. AC motor and helical gear box are from reputed make brands.
Hydraulic screen changer provided for filtration of molten plastic for both extruders.
Die fitted with hydraulic screen changer which converts molten plastic into plastic lumps after filtration. Hydraulic power pack provided for both screen changer.
Plastic lumps drops in hopper of baby extruder. it carry forward molten plastic threads to second screen changer.
Plastic threads passes through air knife. which has blower, helps to remove water from surface of threads. and it moves forward to stainless steel water tank.
Cooling tank is fabricated from stainless steel 304 grade material, which mounted on mild steel fabricated stand. Where guide rollers are provided to convey the threads further towards pelletizer machine.
Pelletizer machine’s stand is fabricated from heavy duty angles, where peletizer unit is mounted which has consisting sets of carbide tips moving blades. peletizer machine is driven by AC motor and AC drives.

Optional Attachments :

Tungsten carbide coated screw and barrel, for high production machines to increase screw life span.
AC drives to maintain motor speed at desired rpm as per raw material requirement.
Pressure transducer along buzzer system for hydraulic screen changer to detect pressure on mesh. (Helps to notify the labor to change screen on right time)(safety feature)
Accumulator power pack for hydraulic screen changer to increase hydraulic up/down speed.
Automatic hopper loader / Vacuum loader to load raw material into hopper with help of blower/vacuum. (substitutes labor)
Air knife, to prevent water entering into pelletizer blade unit and remove water from pellets surface.
Forced feeder, to feed low density raw material easily to increase production rate.
Manual die head, instead of hydraulic screen changer. (to reduce the cost of machine) (best option for virgin material reprocessing)
Barrel vent, for engineering grade materials like ABS and HIPS for moisture free pellets and quality output.
PLC based HMI control panel with touch screen display (Advanced)
Vibro shifter, to separate rejections and finished granules effortlessly.
