The research and development of activated carbon processing machinery is advancing towards large-scale, automated, intelligent, energy-saving and high-efficiency directions. Through technological innovation and layout, domestic and foreign enterprises have made breakthroughs in screening, granulation, firing and other links, promoting the improvement of production efficiency and product quality in the industry. The following analysis is conducted from three dimensions: R&D direction, technological breakthroughs, and enterprise cases:

I. Research and Development Direction: Focus on the dual improvement of production efficiency and product quality

Large-scale and Automation

Activation equipment is developing towards larger sizes and automation, represented by Slep furnaces and multi-stage furnaces. The Slep furnace maintains thermal balance through the combustion of water and gas, featuring low power consumption and stable operation, making it suitable for the production of coal-based activated carbon. Multi-stage furnaces have become mainstream international equipment due to their advantages such as high levels of mechanization and automation, large single-unit production capacity, and uniform and stable product quality.

Intelligentization and energy conservation

The research and development focus has shifted to intelligent control and energy-saving technologies. For instance, by using deep learning algorithms to monitor the status of the production line in real time, potential faults can be predicted and prevented. The residual heat from firing is utilized to heat the mixed gas, reducing energy consumption.

Efficiency and precision

Develop efficient and precise processing equipment for screening, granulation and other links. For instance, the screening device of Anhui Xinhui Carbon Industry achieves multi-layer screening of materials through the coordinated operation of vibration components and adsorption components, significantly enhancing production efficiency. The granulator of Ningxia Nixi activated carbon, through the coordination of the stirring device and the cutting knife motor, granulates activated carbon with uniform particles and stronger stability.
