Description

Bergbaulicher, Rohstoffe, 1953, Vol. 1, p. 64). With garbage that is also directly separated for composting, which can be made up of hard and very soft components because the sieve size has already been reached, these materials cannot be compared. For the crushing of white, the coarse screening machine 2 leaves in the direction C. The chemical ground material such as textiles, paper, vegetables 5 for the intended purpose is not yet satisfactory and sewage sludge has been used in the impact mill so far, the part ground by the impact process is also not used . The professional world has given up, as from a conventional hammer mill 3 at C ₁ . Literature shows for the comminution of garbage. After this last grinding process, the finish leaves all possible grinding devices tried and tested, but the hammer mill 3 at D is good to join with F because of the general prejudice that the rebound can unite the grist from C if necessary If one wants to separate the magnetically detectable material, gen.) the arrangement of a lifting magnet is recommended.

Under certain circumstances it can be advantageous to use the th between the impact mill 1 and the coarse screen 2.

If, however, iron parts from garbage and industrial waste come together from a coarse porcelain mill with non-magnetic parts such as wood or a rotating rotor, they are partly not captured by the magnet separator for pre-shredding, one of these downstream separators, and get into the killed coarse sieve and one of the re-crushing of the hammer mill, where they lead to damage.

The operation of this plant as 35 Surprisingly, it turned out that also every other known garbage shredder working with one or two-ring hammer mills according to the invention was more of a design for pre-shredding instead of the grinding system, but not only because of the high specific hammer mill a particularly favorable wear of the parts exposed to the material to be ground. because that is achieved from the garbage parts, but that the grinding wear manufacturable ^ end product ¹ does not achieve a high price / ae per ton of garbage only a fraction of the previous because combustion and composting make up wear figures, does not cover the costs. Another advantage of the invention with The grinding and processing of garbage throws namely an impact mill provided as a coarse mill system posed technical and economic problems is that the coarse mill includes all garbage by the previously used for this purpose, can be abandoned with borrowed the coarse bulky waste.
