The flotation deinking process of the Flotation Deinking Machine relies on the principle of surface chemistry and froth flotation. Air is introduced into the pulp suspension to generate a multitude of micro-bubbles. Hydrophobic ink particles and impurities attach themselves to these rising bubbles and are carried to the surface to form a foam layer. The foam, containing the removed contaminants, is continuously scraped off from the top, while the cleaned pulp flows out from the bottom. The Flotation Deinking Machine is engineered for high separation efficiency and reliable performance.

In recycled paper pulping systems, particularly for deinking lines processing mixed office waste, newspapers, and magazines, the Flotation Deinking Machine is a core unit. By combining it with other processes such as pulping, screening, and bleaching, mills can produce high-quality deinked pulp suitable for manufacturing graphic papers, tissue, and lightweight packaging grades.

Leizhan’s Flotation Deinking Machine offers a reliable, energy-efficient, and high-performance solution for waste paper recycling plants. Its advanced aeration and flow design help paper mills achieve superior pulp brightness, low residual ink content, and stable operation in continuous production.
