Pulping process mixed with wood chips

The invention relates to a pulping process of mixed wood chips in the wood fiber pulping and paper making industry. The technical proposal is that: 1. storage and production are separated respectively; 2. a siever with the aperture of 8mm is used for sieving wood flour, and the output at the screening working section is properly reduced; 3. washing is carried out, the wood chips are put into a natural settling tank so as to separate out heavy impurities such as sand and the like, and then put onto a cambered slotted screen with the screen cut of 0.2mm so as the separate out light impurities such as wood flour and the like; 4. extrusion and fission and chemicals soaking are carried out, the compression ratio of a screw extrusion press is set to be 1.0 : 2.0, the liquid level in a steeper is raised to 60 percent, the steeping time is set to be 7.5 minutes, and the concentration of the steeped chemicals is 3.0 percent; 5. jordaning is carried out, the tonnage-to-pulp-ratio energy consumption ...
