This week, Kitech Machinery's AGS1600 single-shaft shredder successfully completed its trial run! During this field test, the equipment demonstrated excellent shredding performance on a variety of plastics. On-site video footage demonstrates stable operation, high processing efficiency, and uniform output particle size.

PET plastic bottles are high-value-added waste, with simple recycling methods and relatively mature technology. A comprehensive industry chain has been established both domestically and internationally. Compared to other plastics, PET bottles have a high recycling rate. EU member states, through the establishment of a deposit system, have achieved a recycling rate of around 90%. In 2017, the EU's overall recycling rate reached 58.2%, Japan's was over 92%, and China's PET beverage bottle recycling rate reached over 94%.

Recent research confirms that India has become the world's leading plastic polluter. According to a June 23rd report in India Today, India emits 9.3 million tons of plastic waste annually, accounting for 20% of the world's total plastic waste—equivalent to one in every five pieces of plastic waste worldwide.

Taking a solid step forward in sustainable manufacturing! KiTech Machinery successfully completed a field test of its revolutionary self-cleaning laser screen changer last week, marking a significant breakthrough in efficiency and cleanliness for plastic recycling pelletizing. This innovative technology is designed to address the complex challenges of plastic processing, effectively ending the era of manual screen changes and simultaneously boosting production efficiency and significantly reducing material waste.

During the plastic pelletizing process, various problems often arise, directly impacting pellet quality and the stability of the subsequent extrusion process. The following analyzes common problems and proposes corresponding solutions to quickly identify the issues and optimize production.

A screen changer is a manual or automatic switching device consisting of one or more filters. It is used to remove foreign particles and impurities as the plasticized material flows through the filters. It can be used to filter any type of polymer, rubber, or ceramic melt. A screen changer can be installed on any existing extruder, melt pump, reactor, or other extrusion line.

KiTech Machinery, located in Zhangjiagang, Suzhou, is a leading manufacturer of recycling equipment. Last week, the KiTech KCP80 pelletizing system was tested for pelletizing LDPE film and BOPP film bags. The pellets produced exhibited uniform color, a smooth surface, no bubbles, and excellent heat resistance. The finished pellets can be used for secondary processes such as blow molding, injection molding, blown film, and pipe extrusion, forming a seamless closed-loop production cycle.

Bangladesh's plastic industry has an average annual growth rate of over 18%. With a population of 165 million and cheap labor, it faces a high dependence on imports of raw materials and machinery - China accounts for 65.9% of its raw material supply. This emerging Asian market is opening up a blue ocean of value for global investors.

1. Efficiently deal with complex impurities, suitable for a wide range of plastic types

This week, Kitech Machinery successfully tested the automatic laser filter system with integrated melt pump. The system is designed for efficient filtration of various stubborn impurities in plastic recycling materials (such as PP, PE, LDPE, HDPE, PS, EPS, ABS, PVB, PVC, etc.). It can effectively filter a variety of pollutants including iron, steel, wood chips, paper, textile fibers, unmelted plastics, aluminum, sand, copper, stones, etc., and significantly improve the quality of recycled pellets.

I. Project Overview:

Last week, KITECH Machinery successfully completed the test and verification of the combined system of KCP100-120 compaction and cutting water ring granulator and AGF500/700 crusher. The system is customized for a Mexican agricultural pipe manufacturer. Its process flow is: after the raw materials are crushed by the AGF crusher, they are stably transported through the transfer silo, and finally enter the granulation system through the conveyor belt to complete the granulation.

In the PET recycling process, it is very important to choose the right type of extruder when granulating PET bottle flakes for re-production. Single screw extruder and twin screw extruder are two common granulation equipment, each with its own advantages and disadvantages, suitable for different application scenarios. The following is a detailed analysis of the two extruders and how to choose the right equipment to produce high-quality PET pellets.
