TH46604A - Processes and equipment for classifying paper mixes - Google Patents

Abstract

DC60 (02/02/44) The invention involves a process for classifying the paper mix in which the paper mixture is ground. Fine until a grain size is approximately 20 to 80 mm and the ground paper mixture is separated. By using separate blowing At separation speeds between 1 and 5 m / s into heavy parts containing mixed paper and light parts with toner removal material, high quality section of department store waste paper and high quality parts. Of the ink removal material Can be manufactured in a cost-effective manner The most invention Where, before finely grinding, the paper mixture is separated by a sieve with a sieve hole size of approximately 200 to 450 mm to separate the coarse sections with large area paper sheets. The invention will also involve the separation equipment. Paper ingredient type There is a fine grinder (2) for grinding the ingredients. Paper and separate ejector (3) Finishing mill terminal (2) for separating the crushed paper mixture into heavy and light parts. Separate (3) dryer with cross-section for Separate blowing speed which can be adjusted For separation between 1 and 5 m / s high quality parts of Waste paper from department stores and a high quality portion of disposal material. The ink can be produced in The most cost-effective characteristic according to the invention, where the finer (2) will be pre-positioned by a sieve (1) with a sieve hole size of approximately 200 to 450 mm to separate the coarse sections with a sheet In large areas, the invention involves a process for classifying the paper mixture in which the paper mixture is crushed. Fine until a grain size is approximately 20 to 80 mm and the ground paper mixture is separated. By using separate blowing At separation speeds between 1 and 5 m / s into heavy parts containing mixed paper and light parts with toner removal material, high quality section of department store waste paper and high quality parts. Of the ink removal material Can be manufactured in a cost-effective manner The most invention Where, before finely grinding, the paper mixture is separated by a sieve with a sieve hole size of approximately 200 to 450 mm to separate the coarse sections with large area paper sheets. The invention will also involve the separation equipment. Paper ingredient type There is a fine grinder (2) for grinding the ingredients. Separate paper dryer (3), finer destination (2), for separating the crushed paper mixture into heavy and light parts. Separate (3) dryer with cross-section for Separate blowing speed which can be adjusted For separation between 1 and 5 m / s high quality parts of Waste paper from department stores and a high quality portion of disposal material. The ink can be produced in The most cost-effective characteristic according to the invention, where the finer (2) will be pre-positioned by a sieve (1) with a sieve hole size of approximately 200 to 450 mm to separate the coarse sections with a sheet Large area out

Claims (1)

1.Process for classifying paper ingredients Where the paper mixture will be crushed It is fine to a grain size range of approximately 20 to 80 mm, and the finely milled paper mixture is separated by means of separate blows at a separation speed of 1 and 5 m / s into the heavy parts with Blended paper and lighter parts Contains toner removal material. That has been characterized that before being finely ground The paper mixture is separated with a sieve with a grating hole size of approximately 200 to 450 mm to separate the coarse sections.
