Differences in heating methods of plastic granulators
In China, the geographical distribution of energy resources is highly uneven, and the differences in energy types across regions are even more pronounced. Plastic machinery, such as plastic granulators and pellet machines, requires significant energy input due to the high temperatures needed for processing plastics. As a result, energy costs have become the second-largest expense in the plastic granulation industry, following raw material costs.
Currently, the market offers various types of plastic granulators, primarily powered by electric heating, coal heating, or natural gas. Although electric heating granulators are widely promoted nationwide, electricity tariffs vary significantly across different regions. In eastern China, where power shortages are common, and in western regions with abundant electricity supply, the disparity is particularly evident. Additionally, the difference between northern thermal power and southern hydropower further highlights regional energy imbalances.
Given these conditions, it is crucial to promote plastic granulators that utilize local energy sources in areas with high electricity costs. For example, in regions with sufficient natural gas supply—such as Sichuan, Shaanxi, and Xinjiang—natural gas-heated granulators can be encouraged. In coal-rich areas like Shanxi, Liaoning, and northwestern Shaanxi, coal-fired granulators can be promoted, leveraging local resources to reduce energy costs. This approach not only helps lower operational expenses but also enhances product competitiveness and delivers greater value to users.
By aligning production methods with regional energy availability, manufacturers can optimize efficiency and support sustainable development in the plastics industry. Jiuzhi Plastics Network continues to provide insights and solutions to help businesses adapt to these challenges effectively.
