Installation for disintegrating or grinding brittle products

摘要

In an installation for disintegrating or grinding brittle products, comprising a high-pressure roll press, driven at a high pressing force and disintegrating the product within a stock bed, and a strainer which is disposed downstream of the roll press and whose delivery of coarse product (grit) is at least partially recirculated via a grit delivery line to the product feed shaft of the roll press, in order to ensure that the air squeezed out of the heap of feed products during high-pressure pressing can escape, it is proposed according to the invention to connect at least one degassing line (33 or 34, 33a or 33b) to the product feed shaft (13) of the high-pressure roll press (14), which degassing line opens out into the strainer air inlet line (21) leading to the strainer and/or into the dedusting system disposed downstream of the strainer (19). <IMAGE>
