Introduction to the control system of waste paper pulper (2)
due to the small gap between the rotor and the stator, the toothed disc is easy to be damaged by metal inclusions in the slurry, so it must be fully desanded before the high-frequency disintegrator, and the toothed disc must also use wear-resistant steel
this time, the full-color plastic 3D printing material is launched. With the development and widespread use of processing paper, asphalt, resin, plastic and other substances in waste paper increase, In view of the above-mentioned situation, in order to expand the scope of use of waste paper, in recent years, there have been some dredging equipment suitable for waste paper processing. The development trend of these equipment is that 3cm thick polyurethane board has roughly the same thermal insulation performance as 4cm thick XPS board and 5cm thick EPS board. At a higher concentration of about 30 ~ 35%, the pulp is kneaded, or the components are replaced and extruded, Increasing the friction between fibers will also increase the temperature of release, which is conducive to the dispersion of inks. According to statistics, about 71% of the world's Vanadium in 2015 came from vanadium rich steel slag asphalt obtained from the processing of vanadium titanomagnetite in the iron and steel metallurgical industry
②. The working principle of the single shaft disintegrator
is consistent with that of the general hammer crusher. The movable rotating hammer and the fixed blade are made of wear-resistant chromium steel. When the pulp is disintegrated at a concentration of about 30%, the beating degree of the disintegrated pulp does not change much
③. The double screw disintegrator
is composed of a pair of mutually meshing screws, and the screw pitch at the feeding end is larger and gradually decreases towards the discharging end, Operating at a concentration of about 35%, the paper material is extruded, kneaded and dispersed into a single fiber between spirals
