what is a extruder machine?
Another name of the granulator machine is the extruder machine. The granulators can turn the discarded plastic raw materials into plastic grains or plastic granules through the process of mixing and melting. This process is done to make the recycled plastics heavier, one shape and one color so that they can be sent to the workshop or plastic manufacturing factories for the production of the final product. In fact, the extruder process is a process in which polymer materials (plastic) are melted and come out of a fixed mold under a certain pressure.
Today, plastic recycling machines are in great demand and are designed and manufactured according to the type of plastic and production capacity.
SINGLE STAGE GRANULATOR MACHINE
A single-stage granulation machine is called an extrusion machine that melts and granulates only through one spiral or one stage. People who are looking for polyethylene plastic recycling, this type of plastic recycling machine is suitable. In other words, a single-stage granule machine is one of the simplest and cheapest type of machine. Another advantage of this machine compared to other machines is lower energy consumption and Maintenance cost is less.
TWO STAGE GRANULATOR MACHINE
A two-stage granulator is a device in which plastic materials are melted and mixed through 2 steps or 2 stages. In other words, a two-stage granulator consists of two consecutive granulators, the length and height of the second recycling stage The first is much less. This device is suitable for mixing and recycling plastic with high impurities. This device has a higher quality granule output than the single-stage one. With the 2-stage device, we can also granulate polypropylene, polyamide, ABS and impact plastics.
Not so long ago, when this technology was not yet developed, weak and impure plastics were granulated with a single-stage دستگاه بازیافت پلاستیک twice, which caused double the work of labor and high energy consumption. But today, with two-stage extruders, plastics are recycled with less time and higher quality
GRANULE DEVICE GASIFIER
The gasifier of the granule machine is designed on the cylinder and Mardon. When the plastics have color, impurity or low density, they also need granule gasifier. Plastic produces gas during rotation inside the cylinder, and if this gas is not captured, it enters the final product and creates small bubbles inside the granules. These bubbles in the product can reduce the quality so much that the possibility of its return is high.
The gasifier of the granulator machine is actually related to the Mardon design, where a part of the Mardon is made from a screw to a gear state, and a part of the cylinder is cut so that the gas comes out of the Mardon. The design and implementation of the granule gasifier is completely engineered and depends on the other components of the device. If the gasifier is used incorrectly, the plastic material will be removed from the gasifier part of the device
STRING GRANULATOR MACHINE
The string granulator is actually an extruder that feeds the melted material after the spiral in the form of string or pasta into the water tray and then it is crushed through the cutter blades. Finally, it is packed in the form of seeds in a sack. This type of device is different in the type of device or the output of the device. If you are recycling plastic materials that have high elasticity or elasticity, it is suitable, otherwise the lens granulator is suitable. Nylon recycled materials are suitable for filament plastic recycling machine.
