Abstract
Um bei der Kreislaufmahlung von sprödem Gut zur Herstellung von z. B. Zement, umfassend eine mit hoher Preßkraft betriebene Hochdruck-Walzenpres se mit Gutbettzerkleinerung des Gutes und einen der Walzenpresse nachgeschalteten Desagglomera tor/Sichter, dessen Grobgutaustrag (Grieße) wenigstens zum Teil zum Gutaufgabeschacht der Walzenpresse rezirkuliert wird, zu ermöglichen, daß diese Kreislaufmahlung bei der Regelung mit geringen Systemschwankungen und außerdem mit einem vergleichsweise kleinen bzw. niedrig ge bauten oberhalb des Walzenspalts der Walzenpres se angeordneten Gutaufgabeschacht auskommt, wird erfindungsgemäß vorgeschlagen, daß die Sichter grieße (27) in einem Grießebunker (28) mit Aus tragsmengen-Dosierorgan (29) zwischengespeichert werden, daß der Füllstand (L 1) im Gutaufgabe schacht (14) der Walzenpresse (10) gemessen wird und daß in Abhängigkeit dieses Füllstandes ein Regeleingriff auf das Austragsmengen-Dosierorgan (29) des Grießebunkers (28) erfolgt. In order to recycle brittle material for recycling Production of e.g. B. cement comprising one with high-pressure high-pressure roller press se with good bed crushing of the good and one Desagglomera downstream of the roller press gate / sifter whose coarse material discharge at least in part to the feed chute Roller press is recirculated to allow that this cycle grinding with the regulation low system fluctuations and also with a comparatively small or low ge built above the nip of the roller press arranged feed chute, will proposed according to the invention that the classifiers semolina (27) in a semolina bunker (28) with Aus The amount of the dosing device (29) is temporarily stored be that the level (L 1) in the good job shaft (14) of the roller press (10) is measured and that depending on this level Rule intervention on the discharge quantity dosing device (29) of the semolina bunker (28).
