Plastic Pelletizing Line Components
There are several components that must be included in a plastic pelletizing line. These components include a single screw extruder, water cooling tank, hopper feeding system, and gantry pelletizer. Each of these components has specific functions that must be considered when selecting a line. Below is an overview of these components. Read on to lea more about each. Then, contact a local manufacturer to get a quote for a complete plastic pelletizing line.
Single screw extruder
A single screw extruder is one of the key components in a plastic pelletizing line. The screw feeds the die while the material is heated and compacted. The old theory of extrusion said that the material was "loose" during extrusion and "solidified" as it was compressed. The actual process is quite different.China Plastic recycling machine manufacturers The screw feeds the die. The volume of the extruder screw gradually decreases and the die is "open" or "closed" in its shape.
In addition to the single screw design, a single-screw extruder also features a cokneader, which has pins in the barrel. The pins in the barrel help to wipe the screw surface and reduce the residence time of the material. The pins also interrupt the solid bed to increase over melting rates and lower the material's overall temperature. It is possible to find single screw extruders with a range of features that are best suited for your plastic pelletizing process.
Water cooling tank
A water cooling tank is an integral part of any plastic pelletizing line. Water-cooled brace granulation equipment can be used to produce pellets from waste plastic. The plastic pelletizing machine consists of a feeding system, extruder, die, screen changer, drying fan, and cooling water tank. The pelletizing machine dries the plastic strips, resulting in small, cylindrical particles of one to five microns.
A plastic pelletizing line contains a water cooling tank, a gantry pelletizer, and a parallel twin screw extruder. These units use parallel screw structures and are ideal for mixing plastics with color masterbatch. This type of equipment is mainly used to improve the color of materials, produce new products, and perform advanced teaching experiments. It is also used for masterbatch testing. This article will discuss the benefits of a water-cooled plastic pelletizing line.
Gantry pelletizer
Plastic Pelletizing Line is a complete production line consisting of twin screw extruder, gantry plastic pelletizer, and water cooling tank. This line is designed to produce pellets made of recycled plastics. They are commonly used for new product development, color formulation, advanced teaching experiment, and masterbatch testing. Here are some of the benefits of using this line. You can choose the model that best suits your business.
First, a quality pelletizing line will provide consistent pellet size, shape, and geometries. While many polymers tend to have the same general composition, the quality of pellets will vary. This can cause cutting issues and produce fines. Ultimately, it is important to achieve optimum pellet quality for downstream processing. For this reason, pelletizing equipment must be highly customizable. It is crucial to understand the characteristics of each polymer type.
Hopper feeding system
A hopper feeding system for a plastic pelletizing line allows a consistent amount of raw material to be fed into the extruder. This feed system can be either automatic or manual and consists of a hopper and feeder. During the pelletizing process, several plastic raw materials are mixed together, including various types of resins. During the process, additives such as UV light stabilizers, color pigments, and impact modifiers are added. An accurate feed rate is critical for the production of high-quality plastic pellets. This feed system can be operated as a closed loop using a gravimetric feeder, ensuring the same percentage of materials in every meter of pipe.
The hopper feeding recycling machine feeds materials directly into the extruder without pre-heating the material. This machine can be used for recycling a variety of plastic scraps, including hard plastic scraps. Once processed, the granules can be used for many applications. One model of this recycling machine has a sub-extruder that processes dirty or printed plastic materials. Another model features a force feeder for soft plastics.
Die-face granulating line
A die-face granulating line includes a conical twin screw extruder, a granulator, a die-face cutting mould, and a hopper silo. The process produces rigid and soft PVC granules, which are useful for applications like injection molding, film blowing, and shoe sole. The granulating line can be easily customized and requires minimal maintenance.
This extrusion water ring die face granulating line is a good choice for recycling and LDPE granulating. It features a special water ring die face cutter to ensure granules are cut and shaped correctly. The ring-cutting die face cutter is cooled by circulating water. The plastic pellets produced by this process are uniformly shaped and have excellent properties.
Water-ring pellet cutter
There are several benefits of Water-ring pelletizing systems, ranging from their ease of operation to their versatility. This type of system is often mounted on a process watertank and is considered a single unit. Its range of features includes automatic startup and attention-free operation. In addition, it is highly adaptable, allowing it to be used for a variety of applications. If you're thinking of adding this machine to your plastic pelletizing line, you'll want to think about this.
A water-ring pelletizer is designed to recycle various plastic materials. It works by extruding sheet with the lowest stress level, which makes the finished pellets flat, cylindrical or ball-shaped. Depending on your pelletizing process, you can select a water-ring pelletizer that works with your particular materials. This type of machine will save your company money by minimizing the need for costly new machinery.
