1. Introduction Global plastic waste generation exceeded 400 million tons in 2024, with only 9% effectively recycled worldwide [5]. In China, 19.5 million tons of plastic were recovered—a 2.6% increase from 2023—but over 75% of this volume requires mechanical size reduction before regeneration [1][5]. At the heart of this preprocessing stage lies the plastic granulator, a machine designed to convert bulky, irregular plastic scrap into consistent granules (typically 3–12 mm)...

1. Introduction Plastic waste management remains a global environmental and economic challenge. In China alone, 62 million tons of plastic waste were generated in 2024, with only 19.5 million tons (31.5%) recovered for recycling [2]. Crucially, over 75% of this recovered material must undergo mechanical size reduction before cleaning, sorting, or pelletizing—placing high-performance plastic granulators at the heart of the recycling value chain [2]. While basic crushers suffice for soft,...

1. Introduction Global plastic production has surpassed 400 million tons annually, yet only 9–35% is effectively recycled [1]. In China—the world’s largest plastic producer and consumer—62 million tons of waste plastic were generated in 2024, of which 19.5 million tons were recovered, yielding a national recycling rate of 31.5% [1]. Crucially, over 75% of this recovered material must undergo mechanical size reduction before further processing, placing plastic granulators at the...

1. Introduction Plastic pollution is one of the most pressing environmental challenges of the 21st century. Globally, over 400 million tons of plastic are produced annually, yet less than 9% is recycled [5]. In China, annual plastic waste exceeds 60 million tons, with packaging and bottles accounting for more than 35% [8][10]. To close this loop, mechanical recycling remains the most scalable solution—and at its core lies the plastic shredder....

1. Introduction The proliferation of single-use and durable plastic products has led to mounting waste accumulation in landfills and oceans. Mechanical recycling remains the most economically viable and scalable solution for managing thermoplastic waste. At the heart of this process lies the plastic crusher, which reduces bulky plastic items—such as bottles, pipes, films, and automotive parts—into uniform granules or flakes suitable for washing, separation, and re-extrusion. Recent advancements in crusher...

1. Introduction The proliferation of plastic materials in modern society has created an urgent need for effective end-of-life management. Plastic crushers serve as the primary machinery for size reduction, transforming bulky plastic waste, production off-cuts, and post-consumer items into manageable granules or flakes. This process is the crucial first step in both mechanical recycling, where materials are reprocessed into new products, and in preparing materials for further processing like extrusion...

1. Introduction The ubiquity of plastic in modern life is undeniable, yet its persistence in the environment poses a significant ecological challenge. The transition towards a circular economy, where materials are kept in use for as long as possible, necessitates efficient waste management and recycling technologies. Plastic crushers stand at the forefront of this effort within the industrial sector. These machines are designed to reduce bulky plastic waste—ranging from production...

1. Introduction The demand for precise and reliable cooling is paramount in modern industry and large commercial facilities. From ensuring the dimensional accuracy of plastic parts to preventing overheating in data centers and maintaining comfortable environments in skyscrapers, controlled cooling is not a luxury but a necessity. Among the various cooling solutions available, water-cooled chillers have established themselves as the preferred choice for medium to large-capacity applications where operational efficiency,...
