Process for cleaning the baffle walls in impact reduction machines

The invention relates to a method of cleaning of the prail walls of attached material in the case of impact crumbling flasks with a rotor rotating around a horizontal axis with shredding tools.

With impact crushers of this type, there is a risk, especially in the catchment area of the impact walls, that good settles and thereby the drawing in of the good and thus the throughput performance deteriorates. Particularly This danger exists with moist, sticky or chopped material, so that such a thing becomes completely clogged Impact shredding machines can come. The tendency of the goods, especially in the catchment area of the impact walls to start, is used in impact crushers, such as j Impact hammer mills, impact hammer crushers, hammer mills, promoted by the fact that the material ε by dio crushing tools are thrown against the impact walls at high speed.

So far, it is common for the attached to the impact of such turning Erallzerkleinerungamaschinen Good by DAFL the machine to eliminate "shut down and is scraped off by hand using a Stochereiaens o. Like. The attached Best of the baffles. In addition, attempts have already been made to cause the baffle walls to break down in such impact crushing machines by heating the baffle walls. This is the sngeäetat · Gut? dried, so that its adhesion to the frallwändan is reduced and a Jtfcburst ^l --._ .. - '' BAD ORIGINAL '

Of the large equipment used for cleaning the impact heaters, it is disadvantageous that the plate wall in the area provided to the area can hardly be used in a form for the shredding process and, moreover, a start can be made is subject.
