Plastic squeezer machine is mainly used for dewatering and pelletizing the wet plastic PP PE films and bags, for exmaple, LDPE HDPE PP package films, agricultural films, greenhouse films, plastic shop bags, fresh keeping film bags, garbage bags, hand bags, vest bags and PP jumbo bags, woven bags and sack bags, etc.

The squeezer machines use screw pressing and squeezing way for working, the final mateial moisture could be less than 3-5%, and the material volume can be reduced 50% at least by the pelletizing and agglomerating function. It's more convenient for reuse, storage and transportation of the waste plastic films and bags after processed by the PP PE plastic squeezing machine.

The new developed plastic squeezer machines are very important in the waste plastic film recycling industry.

In the waste plastic film recycling factories, the plastic squeezer machine can replace the centrifugal dewatering machine and electrical dryer of the PP PE film washing line, and cut compactor of pelletizing line is not necessary also. 

By the real using feedback, the plastic squeezer machine can save 30~40% power consumption at least for same capacity requests of plastic film washing line and plastic film pelletizing line.

Consists of the PP PE plastic squeezer machine

1, Motor and reducer

Powerful motor and reducer are installed on the plastic squeezer for smooth squeezing work. famous brands motors and reducers are used, for example , WN, SIEMENS China, SIMO, JIAMUSI motors, and GUOMAO reducers.

2, Barrel and screw

The barrel and screw are made of alloy 38CrMoAlA steel, with nitriding treatement on the surface, more hardness, durability.

Screw has special design to ensure the smooth feeding of films and bags materials.

Barrel with more thickness, and holes on the wall for drainage quickly while the pressing and squeezing to the films or bags, so that to get the high dewatering result.

3, Heater system for the mold

Cast aluminum heaters is used for heating the mold and transit area of barrel, and use to intelligent meters for temperature set and control.

4, cooling system.

Water cooling system is equipped for reducer and mold head cooling.

5, pelletizing system.

A perforated mold is installed on the head of the plastic suqeezer machine, and a cutter with 2pcs or 4 pcs blades are matched with the mold for pelletizing. While the plastic materials are squeezed out from the barrel and mold, the cutter cut the strands on the die face immediately into the pellet shape or agglomerated materials, which will drop into the transit silo and are blown into sysclone silo.

For PE and PP materials, the perforated molds are different.

6, control cabinet.

The control cabinet is used for the centralized control of the plastic squeezer machine. Good quality electrical components and parts are used for making the cabinet, for example, SIEMENS contactor, ORMRON temperature meter, Delta or ABB inverters, etc.

It's very easy for the users to set required technical parameters on the panel, for example, rotation speed, temperature value, etc.

The PP PE plastic suqeezer machine can process different wet PP PE films and bags, no limitation on orginal moisture of the plastic materials. But it can make the good result on dewatering and pelletizing of the materials.

How to feed the materials into the squeezer?

The users can choose the belt conveyor or screw loader to standby the plastic squeezer machine, and it will help to convey the materials into the squeezer from the ground.

Screw loader is more suitable for the materials with high moisture,  and the belt conveyor is usualy for the material with less water content.

Features

Advantage of PP PE plastic squeezer machine in MG Machinery:

1, with different mold designs,  Both PP PE films and bags can be squeezed. 

2, dewatering and pelletizing functions by one time processing. 

3, high dewatering rate, final moisture less than 3~5%.

4, good semi plasticizing function, no effect to material quality in the after process like pelletizing.

5, hard teeth reducer, big torque for squeezing.

6, alloy 38CrMoAlA for making barrel and screw, durability.

7, PLC control, easy operation for parameter set by different materials conditions.

8, low rotation speed, lower noise.

9, heavy structure, steady working.

10, cyclone system for materials discharging, less labor required

11, quality certificate.
