PP PE rigid/hard Scraps Flakes Single Screw cascade extruder with strand Granulator

PP PE rigid/hard Scraps Flakes Single Screw cascade extruder with strand Granulator

Device overview

Single Screw cascade extruder with strand Granulator is mainly used for processing rigid flakes, crushed flakes, regrind flakes, hollow container, buckets, Such as deskes, chairs, milk bottles, baskets and car parts. 

After crushed,washed and dried, then the plastic flakes need to be granuated by extruders. Finally hese granules can be further processed into various plastics products by blowing, injection and calendering. The total granulation line combines quantitative feeding, high efficiency extruder,different types of filter and different types of pelletizer by modular design.

Rotary charger

As a special design, send the crushed rigid flakes material into the feeder on the extruder by screw. The equipment use inverter to control the speed. It can control together with the Feeder, If the material in the feeder is full, then the rotary charger will stop by itself.

Feeder the material into the extruder evenly and stably. If people don’t use feeder, the extruder maybe choked in the mouth.

Screw and barrel on extruder

Special designed by different material(screw and barrel) ,to plastify, heating different material, each material the temperature, screw design is different.And the material of screw and barrel is 38CrMoA1A, Nitrogen treatment or Bimetallic to keep the life of screw and barrel.

Heater on the extruder

Usually there are several zone on the extruder, each zone need heater, so we can use cast copper, cast Al aluminium, Ceramic heater, electricity heater, each heater has its own advantage or disadvantage. We will use the heater up to different material character.

hydraulic filter.jpg

Screen changer

The hydraulic screen changer will filter out and remove the impurities inside of the material. There are several types of screen changer: Single plate screen chager, round bar screen changer and laster filter. Customer can use any kind of screen according to the dirty of raw material and where you will use the final pellets.

Laster filter

Laster filter we also called no mesh screen changer. It no need to change the mesh all the time, the cutter on the filler will clean the mesh by itself. So it can save much more material.

pelletizer die.jpg

Die head

There is die head in water-ring pelletizing system. According to different raw material, the dies are also different. And the size and numbers of the hole in the die can be designed as requirement.
