Nguyên lý của máy nghiền khuôn vòng và sự phát triển của nó

Bài viết này tập trung vào máy tạo viên khuôn tròn và đề cập đến nhiều khía cạnh khác nhau:

The first is the background of the study, ring die pelletizer plays an important role in feed processing, however, there are problems such as poor production quality, low efficiency and short life span in China.

Its structure consists of five parts such as conditioner, feeder, etc., in which the pressure roller and ring die play a key role in the quality and efficiency of granulation.

The working principle is divided into feeding zone, deformation compression zone and extrusion forming zone, and the raw materials finally form products under the joint action of ring die and pressure roller.

In terms of development status, China started researching in the 1980s, and now ushered in an opportunity for improvement and innovation. Some countries already have a complete technical system, domestic universities and research institutes, although the research continues to deepen but there is a certain degree of one-sidedness, China is still in the early stages of development, there are performance, power consumption and other issues, but the Ministry of Agriculture has completed the relevant research and built production lines.

In the promotion of prospects, straw should be made of biomass particles to promote the full range of environmental protection and pelletizing machine with high efficiency, good quality and low energy consumption. Europe and the United States market has replaced coal pellet fuel, China has not been popularized but is expected to realize the future replacement.

Development trend, the current use of active roller and ring mold, domestic and foreign will strongly support the development of more efficient, easy to operate, high degree of automation ring die granulator. There is a gap between China and foreign countries, and the introduction of technology can be considered.

Finally, the main direction and outlook, the study of granular compression material has a certain foundation, but the research experience of ring die is insufficient. In the future, we should focus on the study of ring die failure and structural compensation, to provide a basis for the design of new structure ring die.
