Plastic Film Washing Line:

 

Greenhouse covering film:

The Greenhouse covering film washing line is consist of crushing part,washing part,drying part. The working steps should be like below:

1) Bale cutter

2) Trommel screen

3) Film crusher

4) Friction washer

5) Film floating washing tank

6) Squeezer

7) Packing hopper

 

Feature:

Stone removing system:

This design is made by RETECH recycling R&D team,we fully consider the features of LDPE agriculture greenhouse covering film. The film is usually dirty with soil,stone,metal.Due to this situation, RETECH Machinery suggest to cut the big baled film into small firstly by our hydraulic bale cutter machine.The cutted film will get rotate slowly in trommel screen,here the small stones and soil will fall down from the screen. The film will send to next for crushing.

 

 

Film Crushing system:

Our film crushing system is the most advanced for cutting PE PP film bags,with special structure on design to processing PE film,the angle is perfectly to cut in 22.5 degree.The moving blades are in shape of staggered step type,the current is very stable while cutting film with low noise.

The rotors are with tempering treatment and dynamic balance treatment.

Final film size is controlled by mesh hole,it is usually 40-60mm.

 

Models of RTPC Crusher:

Model	Motor power	Rotor diameter	Capacity
RTPC800	37KW	800*560mm	300kg/h
RTPC1000	55KW	1000*560mm	500kg/h
RTPC1200	90KW	1200*620mm	1000kg/h
RTPC1400	132KW	1400*760mm	2000kg/h

 

Film Washing System:

After crushing system,the film will fall into low speed friction washer machine. With speedy moving,the dirt will more cleaned here. It will help reduce the washing pressure in next floating washing tank.

The film is widely washed in film floating tank by constantly washing rollers. Film roll over in the washing tank and pushed forwarder.

 

Models of RTF Washing Tank:

Model	Motor power	Dimensions	Capacity
RTF4500	1.5KW*2	4500*1320mm	300kg/h
RTF6000	1.5KW*3	6000*1600mm	500kg/h
RTF8000	2.2KW*3	8000*2000mm	1000kg/h

 

Squeezing drying system:

RETECH has 2 recommend on film drying system.

1^st option is working with centrifuge dryer,it is working with high speed centrifuge force to remove water from PE film flakes. It will not change the shape of film,final moisture will be in 5%-8%.

 

Models of RTCD Centrifugal dryer machine:

Model	Motor power	Speed	Capacity
RTCD300	45KW	1440rpm	300kg/h
RTPC500	75KW	1440rpm	500kg/h
RTPC1000	110KW	1440rpm	1000kg/h

 

 

2^nd option is working with squeezing dryer,it is working by extruder heating and compacting. The film will changed to granules shape.final moisture will be 3%.

 

Models of RTSD Squeezer:

Model	Motor power	Screw diameter	Capacity
RTSD300	90KW	300mm	400kg/h
RTSD500	132KW	320mm	600kg/h
RTSD1000	160KW	320mm	800kg/h

 

 

The whole LDPE LLDPE PP film washing line is designed and manufactured by RETECH Machinery.We also accept customzied design and production.

 

We also supply water treatment plant for plastic washing machine.

 

Plastic Film Granulating Line:

 

PE film granulating machine is consist of below:

1) Belt conveyor with metal detector

2) Compactor/Agglomerator

3) Extruder with degassing

4) Filter screen changer

5) Die face cutting system

6) Granules Dryer

 

PE film will get next granulating/pelletizing after processing by washing machine. It is important to choose the right granulating machine as per your plastic materials. We here recommend our solutions, customer can select the proper machines based on your condition.

 

PP PE film Single stage water ring die face pelletizing machine:

 

The single stage pelletizing machine is with only one stage extrusion and one filtration system. It is working aim at the clean film,offcut LDPE HDPE film,leftover LDPE LLDPE HDPE film. Such like HDPE T shirt bag, virgin film.

 

The film is dry and clean,it is no need to dirt removing, just need granule making.

Model	Motor	L/D	Screw Diameter	Capacity
RCDJ85	55kw	33:1	85mm	160-200kg/h
RCDJ100	90kw	33:1	100mm	260-320kg/h
RCDJ130	132kw	33:1	130mm	450-550kg/h
RCDJ160	220kw	30:1	160mm	600-750kg/h
RCDJ180	250kw	28:1	180mm	800-1000kg/h

 

PP PE film Double stage water ring die face pelletizng machine:

 

The double stage pelletizing machine is working with washed film, these film may contains some dirt and water. So,it is better to add a sub extrusion machine for 2 times filtration. We will also add a dust-water removing system on the top of agglomerator/compactor.

 

Model	Motor	L/D	Screw Diameter	Capacity
RCSJ85	55kw	33:1	85mm	160-200kg/h
RCSJ100	90kw	33:1	100mm	260-320kg/h
RCSJ130	132kw	33:1	130mm	450-550kg/h
RCSJ160	220kw	30:1	160mm	600-750kg/h
RCSJ180	250kw	28:1	180mm	800-1000kg/h

 

Features:

 

1) Belt conveyor

For sending the soft film into compactor machine,working with metal detector to find metals and protect the blades in compactor and screw in extruder.

 

2) Compactor/Agglomerator

Working with moving and fixed blades which has friction force in 500 RPM speed, it create the heat and compact the film. It is feeding controlled by current.

 

3) Extruder and degassing

Melt the plastic and degassing the useless cells. The film will get totally plasticizing and heating,the end filtration system will stop the impurities.

 

4) Die face cutting system

With new technology on cutting part, we can achieve to cut the PP PE in one machine. The water ring around in best angle will ensure the cutting granules uniform.
