How does the granulator save energy? – Suzhou Polytime Machinery Co., Ltd.

A plastic granulator refers to a unit that adds different additives to the resin according to different purposes and makes the resin raw materials into granular products suitable for secondary processing after heating, mixing and extrusion. Granulator operation involves a wide range of fields of the national economy. It is an indispensable basic production link for many industrial and agricultural products. In recent years, China's industry has developed rapidly, the market is prosperous, the supply of waste plastic particles is in short supply, and the price rises again and again. Therefore, the treatment of waste plastic particles will become a hot spot in the future. As the main treatment machine, the recycled plastic granulator will have many customers.

What is the main purpose of the granulator?
It is suitable for the production of different colors of PP, PE, PS, ABS, PA, PVC, PC, POM, EVA, LCP, PET, PMMA, etc. Plastic granulator changes the physical properties of plastics through the process of high-temperature melting, plasticization, and extrusion to achieve the plasticization and molding of plastics. It is mainly used for processing waste plastic films (industrial packaging film, agricultural plastic film, greenhouse film, beer bag, handbag, etc.), woven bags, agricultural convenience bags, pots, barrels, beverage bottles, furniture, daily necessities, etc. Granulator is suitable for most common waste plastics. It is the most widely used, widely used, and most popular plastic recycling processing machine in the waste plastics recycling industry.

How can the granulator save energy?

The energy-saving of the granulator machine can be divided into two parts, one is the power part and the other is the heating part.

Most of the energy-saving of the power part adopts a frequency converter, and the energy-saving way is to save the residual energy consumption of the motor. For example, the actual power of the motor is 50Hz, but in production, it only needs 30Hz, which is enough for production, and the excess energy consumption is wasted. The frequency converter is to change the power output of the motor to achieve the effect of energy-saving.

Most of the energy-saving of the heating part adopts electromagnetic heater, and the energy-saving rate is about 30% - 70% of the old resistance coil. Compared with resistance heating, the advantages of electromagnetic heater are as follows:

1. The electromagnetic heater has an additional insulation layer, which increases the utilization rate of heat energy.

2. The electromagnetic heater directly acts on the material pipe heating, reducing the heat loss of heat transfer.

3. The heating speed of the electromagnetic heater should be more than one-quarter faster, which reduces the heating time.

4. The heating speed of the electromagnetic heater is fast, the production efficiency is improved, and the motor is in a saturated state, which reduces the power loss caused by high power and low demand.

With the continuous development and improvement of plastic preparation and molding technology, the use of plastics will further increase, and the attendant "white pollution" is likely to continue to intensify. Therefore, we not only need more high-quality and cheap plastic products but also need perfect recycling technology and mechanism. Suzhou Polytime Machinery Co., Ltd. has established a reputable company brand in the world through many years of experience in the plastic industry, and its products are exported all over the world.
