APMP Pulping Process Flow Instruction
1.The process flow is suitable for wood materials like poplar,
birch, maple, eucalyptus, spruce, wheat straw, reed, cotton stalk, straw, bamboo, etc. Chemi-mechamical pulp is divided into bleached and natural colour. Bleached chemi-mechamical pulp can be used for copy writing paper, toilet paper, offset paper, electrostatic copy paper, LWC, coated paper, newsprint, etc. Natural colour chemi-mechamical pulp can be used for corrugated paper, wrapping paper, natural color life paper. The process is suitable for wide range of capacity, can be used in 50-300t/d chemi-mechamical line with yied rate of 85%.
2. The process flow includes wood chips preparation section, wood chips washing and thickening section, double screw kneading section, bleaching section, high consistency refining section, black liquor extraction section, low consistency refining section, fine screening section, pulp washing and thickening section.
3.Wood chips preparation section mainly includes wood chips belt conveyor, multilayer swinging screen, front hopper type lift, belt conveyor, feed bin, discharging belt conveyor, back hopper type lift.
4.Wood chips washing and thickening section mainly includes wood chips washer, inclined screw dewatering machine, steam chamber. It is used to wash and thicken wood chips, to remove impurities, to steam and soften the wood chips.
5.Double screw kneading section adopts twin-screw kneader, to press and squeeze the steamed wood chips. Also, chemicals like oxydol can be added for bleaching.
6.Bleaching section uses reaction chamber to hydrogen peroxide bleaches the kneaded pulp. Bleaching time is about one hour.
7. High consistency refining section uses high consistency refiner, in condition of high temperature, high consistency, high speed, carry out high consistency beating process to the bleached pulp, to increase beating degree and wet weight of pulp. To get long service life, parts contacting with pulp are all stainless steel.
8.Black liquor extraction section uses single screw press master to wash and thicken the pulp, to extracts black liquor and purify the pulp.
9.Low consistency refining section uses DD double disc refiner, constant power or energy consumption. It has stable pulp beating effect, increased pulp beating degree and wet weight. To get long service life, parts contacting with pulp are all stainless steel.
10.Fine screen mainly includes 2-stage or 3-stage fine screen, slag pulp refiner, 2-stage low consistency cleaner. Fine screen drum rotor and corrugated bar screen drum matches to each other effectively, which can save energy and increase the output. Slag pulp refiner deals with the tailings pulp of fine screen, which can increase the yield rate. 2-stage low consistency cleaner can only exhausts slag for tailings pulp of fine screen. Main flow has no low consistency cleaner, which can greatly save the energy consumption.
11.Pulp washing and thickening section uses gravity disc thickener and twin-wire press master. Disc thickener is used for washing and thickening of pulp, and is suitable for approach wire pulp-regulating system. Twin-wire press is used for washing and thickening of pulp. When consistency of pulp reaches beyond 30%, the pulp can be sold.
12.Choice of the process flow and pulping equipment is based on paper grade, raw material, output, so meeting the customer needs and lowering the running cost is primary.
