What is a one -step granules machine?
The single-stage granule machine consists of a spiral. This device uses European design and advanced technologies. Plastic materials and waste are sent to the compactor cutting section through the conveyor belt. The condensing cutter can effectively dry the materials. In this section, the condensing cutter rotates at high speed to enter the single-mardon extruder to crush the materials.
The hydraulic screen is installed on the extruder head to remove the impurities in the material and improve the granulation quality. Also, in this device, it uses a special screw for cutting and compressing plastics to remove moisture. Single stage granulator is commonly used for:
✾ Recycled polyethylene plastics
✾ Polyethylene films
✾ PP films
✾ Polyethylene sheets
✾ Polyethylene sheets PP and PS
✾ polyethylene masses
What is a two -step granul maker?
The two-stage granulator consists of two parallel spirals side by side. This machine is made of a double Mardon extruder and a single Mardon extruder. One of the main features of this device is high speed of work, low heat generation, low energy consumption. The polymer in the two-stage granulation machine must pass through the mesh filter at each stage after melting to provide only pure and clean granules. This machine is more suitable for soft polymers due to its two-stage operation. The alloy material of the device does not rust and it is equipped with two gasification systems. The produced granule is converted into raw materials through a two-stage granulator machine and is used in various industries. The two-stage granulation machine is usually used for the following:
✾ polyethylene granules
✾ rubber
✾ granules of soft polymers such as nylon and sacks
✾ polymers with high gas
✾ Impact
✾ Petrochemicals
Difference of two -step granulism and one -stage
The two-stage granulation machine produces higher quality and purity materials than the single-stage one with high tonnage and capacity. Two-stage granulators are usually used for times when the need for more recycled materials is felt. One of the most important reasons for using a two-stage granulator is the existence of a gasification system. This system does not exist in single-stage type. The gasification system can increase the amount of gasification from granules by increasing the length of the cylinder and extruder and increasing the number of filtering times. In general, the quality of the granule produced by the two-stage machine is higher than the one-stage one.
