Performance of plastic cleaning and separation machine in paper mill: It generates high-intensity eddy currents and strong pulping effects during operation, promoting the full swelling, thinning, and dispersion of various paper fibers into single fibers, avoiding excessive cutting, damage, and affecting fiber length and strength. Effectively avoid the breakage of light impurities such as plastic sheets and adhesive backing sheets to facilitate screening and removal. Under medium concentration conditions (4-12%), the fibers rub, squeeze, and knead each other strongly, causing various membranes to separate from the fibers. At the same time, the pulp suspension has low viscosity and strong fluidity, causing the fibers to absorb water and swell, becoming soft and plastic, which is conducive to plastic separation.
