Definitions
- the invention relates to a process for the wet treatment of materials, in particular ores and minerals or the like materials by Kreislaufmahlrea in a container mill and classification of
- the coarse material arriving at the underflow of the hydrocyclone arrives after a first cyclone aeration on a screening device in order to carry out a second classification, whereby separated fine material is removed and only remaining coarse material is added to the mill circuit and this is relieved thereby.
- the mill outlet is first pumped onto the hydrocyclone with correct separating cut for free-milled product.
- the overflow of the hydrocyclone is then already well conditioned for further processing.
- further processing steps may be followed by a flotation, a magnetic separation or the like. This good Conditioning takes place taking into account the fact that the otherwise desired maximum thickening does not have the highest priority in the lower reaches during operation.
- the cyclone feed can be diluted to cause a better selectivity.
- Coarse product to reduce by a factor of 2 to 4 compared to the prior art.
- the figure shows a system diagram of a device for
- a mill 1 has a task 2 and a discharge 3.
- the task 2 water (H 2 0) u and the material to be ground M is fed and set the Mahi perspectives in motion.
- the upper section of the hydrocyclone leads to exit A.
- the coarse material arriving at the underflow 6 of the hydrocyclone 5 reaches a sieve arrangement 7.
- the screened fine material reaches the exit A '.
- the screened coarse material of the task 2 of the mill 1 is supplied. Due to the additional separation of the fine material, the mill is in this regard relieved and a Totmahlen avoided, the egg in a pure Kreisla ufmahl ing with hydrocyclones entering effect, after which returns over the cyclone underflow at high solids concentration in the feed much fine grain to the mill, is not given.
- hydrocyclones separate not only according to grain size but also according to the specific gravity of the individual particles
- the value mineral e.g. Iron
- the tailings material e.g. B. S1O2.
- the present invention downstream screen for the lower reaches of the hydrocyclone separates only after the grain size, i. heavier Wertm ineral in Trennkorn Kunststoff is in the sieve to
- Value product can be enriched.
- Investing costs for mill and drive as the grinding mill and drive can be made smaller with a narrower grinding belt.
- the narrower grain band also has a lower specific surface area to be produced.
