Technology
The Deswik Mill is of vertical construction, manufactured in mild steel/stainless steel,
with all wetted parts lined with hard wearing and contamination-free polyurethane resin.
The chamber is water jacketed for cooling. A separate heat exchanger system is also available.
The impeller is a patented turbo-disc design unique to the Deswik Mill. It is designed
in such a manner that its assembly is modular and the configuration may be changed to
achieve different end product size and distribution characteristics.
The Deswik Mill is available in a range of sizes, from 250 litre mills delivering
four (4) to eight (8) tonnes per hour (t/hr), to 5,000 litre mills delivering
75 – 150 t/hr dependent upon the required end product size.
The Need for a fine-grind – In the rougher
circuit the question is how coarse can we grind and obtain the highest
recovery? In this circuit the focus is on liberating enough of the
surrounding gangue material to enable the target mineral to be recovered for
downstream processing.
In the cleaner circuits the comparative question raised
is how fine do we need to grind the rougher concentrate to produce a high
grade product? The focus here is directly on target mineral liberation and a
trade off on grinding energy requirements and downstream processing.
The Deswik mill enables a client to specifically and
accurately target specific grind sizes with an extremely low standard
deviation thereby optimising the downstream processing
