single screw extruder for plastic recycling pelletizing system

Short Description:

A single screw extruder is a common type of extrusion machine used in the plastics industry for processing and recycling plastics. It is typically used for processing materials such as squeezed films or rigid flakes, which are common byproducts of plastic manufacturing and recycling processes.

The operation of a single screw extruder involves feeding the plastic material into a hopper, which is then transported along a rotating screw within a heated barrel. The screw applies pressure and heat to melt the plastic and force it through a die, which shapes the plastic into the desired product or form.

To use a single screw extruder for recycling squeezed films or rigid flakes, the material first needs to be prepared by cleaning and shredding it into small, uniform pieces. These pieces are then fed into the hopper of the extruder and processed as described above.

Single screw extruders are versatile machines that can be used for a wide range of plastic processing applications, including recycling and extrusion of various plastic materials. They are widely used in the plastics industry due to their efficiency, reliability, and cost-effectiveness.

Single screw extruder plastic recycling pelletizing system

The single screw extruders have been developed for a very basic form of extruder that simply melts and forms the material. Due to their low cost, simple designs, ruggedness, and reliability, single screw extrusion machines are one of the most popular extruding machines and widely used for all kinds of plastics recycling. The most popurlar is the PP and PE recycling.

SJ Series is single screw extruder recycling pelletizing system is a specialized and reliable system which suitable to the recycling and re- pelletizing. It combines function of plasticization and pelletizing to one step. It could be used in recycling the plastics, such as crushed PE, PP bottles and drums flakes and washed and squeesed dry PE films, also the ABS,PS,PP from the waste pallets, chairs, appliances etc. The plastic recycling machine’s capacity can be various from 100-1100kg/h.

1.For the rigid plastics pelletizing, such as the The screw of the extruder is special designed for the different comparatively contaminated plastics with two times filtering. It can do the PP,PE,ABS and PC rigid plastics and the washed squeezed PP,PE films . The barrel can be wind cooling or water cooling. And the pelletizing type can be watering pelletizing, strand pelletizing and underwater pelletizing.

2.For the washed and squeesed drying PE PP films. The moisture of the raw material need to be within 5-7%. It is with large silo with screw to automatically transfer the material into the belt, which will transfer the raw material into the extruder.

The machine is with two stages can effectively filter the impurities and are easy to pelletize the raw material in the watering pelletizing system.

According to customer request, we can make the pelletizing system to strand pelletizing or underwater pelletizing.

Characteristic:

With advanced design, high output, good plasticizing, low consumption, and spline gear transmission, it has the advantages such as low noise, stale running, good bearing capacity and long life.

The single screw extruder recycling pelletizing system offers a cost-effective and efficient solution for recycling plastic waste, as it can process a wide range of plastic materials and produce high-quality pellets that can be used in a variety of applications. It also helps to reduce the amount of plastic waste that ends up in landfills or the environment, contributing to a more sustainable and eco-friendly manufacturing process.

A plastic recycling and granulating machine is a type of equipment used to recycle plastic waste into granules or pellets that can be reused in manufacturing new plastic products. The machine typically works by shredding or grinding the plastic waste into small pieces, then melting and extruding it through a die to form pellets or granules.

There are different types of plastic recycling and granulating machines available, including single-screw and twin-screw extruders. Some machines also include additional features such as screens to remove impurities from the plastic waste or cooling systems to ensure the pellets are solidified properly.

Plastic recycling and granulating machines are commonly used in industries that generate large amounts of plastic waste, such as packaging, automotive, and construction. By recycling plastic waste, these machines help reduce the environmental impact of plastic disposal and conserve resources by reusing materials that would otherwise be discarded.
