The Influence Of Environmental Factors On The Performance Of Twin-screw Extruders And Selection Guidelines
More and more companies are seeking solutions that can meet production efficiency and reduce environmental impact, and twin screw extrusion technology is demonstrating its unique value in this context.
1. The influence of environmental factors on twin screw extruders
Environmental factors such as temperature, humidity, and cleanliness directly affect the working efficiency and service life of twin screw extruders. In non isothermal environments, the stability of the extrusion process and the quality of the product will be significantly affected.
Research has shown that twin screw extruders in a fully engaged state perform well in non isothermal environments, resulting in high shear rates and moderate viscosity of polylactic acid melt, which is beneficial for efficient and high-quality extrusion of polylactic acid.
The fluctuation of environmental temperature will directly affect the heat exchange efficiency of twin screw granulators, leading to an increase in energy consumption. The latest research in 2025 found that in high temperature and high humidity environments, the energy consumption of twin screw extruders may increase by more than 15%.
A clean production environment is equally important for the twin screw extrusion process. Dust pollution not only affects product quality, but may also accelerate equipment wear and shorten the service life of twin screw extruders. Maintaining a clean environment has become a fundamental requirement for high-quality extrusion production.
2. Environmental advantages and technological innovation of twin screw extruder
Twin screw extrusion technology essentially has the advantages of energy conservation and environmental protection. Compared to traditional equipment, modern twin screw extruders can significantly reduce energy consumption through optimized design.
The conical co rotating twin screw cable material granulator has the characteristic of ultra-low energy consumption. The lowest power consumption for producing 1 ton of finished product is only 90 degrees, which saves more than 50% of electricity compared to single screw extruders and parallel co rotating twin screw granulators of the same model on the market.
The twin screw extruder also exhibits excellent material adaptability, capable of processing recycled materials and biobased materials. Research has shown that using a twin screw granulator can add a high proportion of calcium carbonate and recycled materials, greatly reducing production costs and environmental burden.
3. Market Trends and Environmental Protection Needs of Twin Screw Extruders
The global twin screw extruder market is steadily growing, with an expected market size of $1.7 billion by 2031 and a compound annual growth rate of 2.3% in the coming years. This growth is largely driven by the demand for environmental protection.
The demand for twin screw extruders is constantly increasing in fields such as food processing, pharmaceuticals, and new energy materials. These industries have extremely high requirements for clean production and environmentally friendly processes, promoting innovation and development of twin screw extrusion technology.
Efficient and energy-saving twin screw extruders with intelligent control will become the mainstream in the market. Intelligent control technology can adjust process parameters in real time, adapt to environmental changes, and ensure that the production process is always in the optimal state.
The tightening of environmental regulations is driving companies to replace old equipment. The new twin screw granulator not only meets stricter emission requirements, but also recovers investment costs in a shorter period of time through energy-saving features.
4. How to choose an environmentally friendly twin screw granulator
For customers who pursue environmental protection and high cost-effectiveness, multiple factors need to be considered when choosing a twin screw granulator. Firstly, evaluate the energy consumption indicators of the equipment and select models with energy-saving technologies.
Material adaptability is a key consideration factor. A high-quality twin screw extruder should be able to handle a variety of raw materials, including recycled materials and biodegradable materials such as PLA. The environmental adaptability of the equipment cannot be ignored. To consider the environmental requirements for equipment operation, choose a model that can adapt to local climate conditions and avoid production stability being affected by changes in environmental temperature and humidity.
Consider the self-cleaning function of the device. The twin screw extruder has a small gap at the meshing part, so the meshing area has a relatively high shear speed, which can scrape off any accumulated material stuck to the screw and has a very good self-cleaning effect.
Pay attention to the manufacturer's environmental commitments and technical support capabilities. Choosing an enterprise like Nanjing Kelongweier Chemical Machinery Co., Ltd. that values environmental innovation can provide more sustainable technological upgrade support and environmental solutions.
Choosing a suitable twin screw granulator is like choosing a long-term partner to accompany the growth of a company.
As an industry innovator, Nanjing Kelongweier Chemical Machinery Co., Ltd. has always been committed to developing efficient and energy-saving twin screw extruders that can adapt to various environmental conditions, helping customers improve production competitiveness while reducing environmental burden.
With the continuous advancement of environmental protection technology, twin screw extruders will inevitably become a key part of the green manufacturing system, providing more sustainable material solutions for many industries.
