It can also be equipped with two stage granulation system, using two extruders to pass the material through secondary filtration, making the produced particles cleaner and higher quality;

Product Details

Plastic Granulator Machine Description:

The production line adopts European design and advanced technology. It is mainly used for clean PE PP films, scraps and crushed, washed, dried HDPE/LDPE/PP/PS materials. The material is sent to the compactor cutter through the conveyor belt, and fed into the single screw extruder by high speed rotation of the compactor cutter;

The screw is specially designed for cutting and compacting plastics. It has the advantages of fast feeding, wear resistance, etc., with natural exhaust and vacuum system; It can effectively remove the moisture inside the material; this extruder uses ceramic heating ring, durable and easy to maintain.

Compactor cutter can effectively dry materials, agglomerate, friction self-heating, high-speed forced feed into the screw after the material reaches a certain temperature, improve the output and reduce the heating of the screw to the plastic, accelerate the plasticization process; effective Energy savings;

Hydraulic screen changer is installed on the extruder die-head to effectively remove the impurities in the material; different quality of the finished product can be produced through the use of different mesh filters;

The special design of the extruder head part can effectively remove the hidden moisture inside the material and improve the granulation quality;

It can also be equipped with two stage granulation system, using two extruders to pass the material through secondary filtration, making the produced particles cleaner and higher quality;

It also can be equipped with a vibrating screen to sort out unqualified products; making the product particle size uniform and nice looking. The follow-up pelleting type can choose to strand/noodle pelletizer, or die face cutting (water ring pelletizer) to save labor and reduce waste;

The production line can be specially designed according to the cleanness of the customer's raw material and the quality requirement of the final product;

Analysis of the Current Situation of Plastic Granulator Technology Development

The plastic granulator involves a wide range of national economy. It is not only an essential part of the production of a large number of industrial and agricultural products. The plastic granulator is also a large energy consumer in China, and its energy consumption accounts for about 12% of the total energy consumption of the national economy. In addition, the pollution caused by the plastic granulator process is often an important source of environmental pollution in China. The improvement of plastic granulator machine technology has a very close relationship with the development of the entire national economy.
Faced with serious energy and environmental challenges, China has recently taken a comprehensive, coordinated, and sustainable outlook on scientific development as its guiding principle, and formulated a mid- and long-term energy science and technology development strategy and development plan to 2020, which is the formulation of this energy and environment development strategy. It also pointed out the direction for the development of Chinese plastic pelletizer technology, and it is imperative to explore the new development path of plastic pelletizer machine technology.

First of all, the plastic granulating machine operation involves a very wide range of fields, and China’s plastic granulation energy consumption accounted for almost half of the energy consumption of the entire industry, reaching 12%.
Second, the plastic granulator’s environmental pollution is also quite grim. Among the most widely used types of conventional plastic granulator equipment, more than three-quarters of them are hot air plastic granulators. These types of plastic pelletizer equipment have very severe environmental pollution, and are used for burning coal in plastic granulator systems. The transformation of the furnace has become an important issue to be solved. The energy efficiency of the progress of the plastic granulator process and the prevention of environmental pollution are mutually reinforcing. Reducing the energy consumption of 100 million tons of standard coal will re`duce CO2 and SO2 emissions by more than 64 million tons in China, and its environmental benefits will be significant.
Therefore, when exploring the new development path of plastic granulator technology, it is necessary to comprehensively consider energy efficiency, environmental protection, and product quality in order to achieve comprehensive, coordinated, and sustainable development. To implement the development strategy of high-efficiency and green plastic granulators, we must first take the path of resource-saving development and change the single, extensive plastic granulator into a combination and intelligent plastic granulator. It is necessary not only to fundamentally transform the plastic granulator process, but also to carry out comprehensive and multi-level energy-saving technological transformation, and to develop plastic granulator technology that applies renewable energy and industrial waste heat.
