:: Maelgwyn Mineral Services Represents the Deswik TM Ultra Fine Grinding Mill

Maelgwyn Mineral Services have recently signed an agreement to exclusively represent the Deswik TM ultra fine grinding technology in the principle market areas of Europe and the Asia Pacific region. It will also be utilized in conjunction with Leachox, the companies’ proprietary process for refractory gold and base metal recovery. The Deswik "Turbo Microniser" mill has been developed in South Africa by Deswik (Pty) Ltd under the guidance of the father and son partnership of Des and Wikus Erasmus (Hence the name "Deswik").

The Deswik TM mill is a new development of the vertical stirred mill type especially designed for ultra fine grinding. Depending on the conditions the mill can grind down to micron size at low energy and grinding media consumptions. The revolutionary impeller design and internal circulation system means that the mill can operate with impeller tip speeds much higher than previously achievable in UFG mills and without forcing the grinding charge to the top of the mill. The higher impeller speeds dramatically increases the grinding efficiency in the mill. Being able to operate vertically in an open pressure environment avoids the need to seal the system which can be troublesome and expensive in vertical and horizontal UFG mill types.

An MMS subsidiary owns and operates a 5 tph Deswik TM mill as part of its Leachox process licensed to a gold mine in South Africa. The Deswik TM mill can scale up to handle larger throughputs and a 50 tph mill has been designed. MMS is installing a laboratory mill in conjunction with its Imhoflot G-Cell flotation and Aachen reactor technology at the CLEER facilities of the Engineering Department of Cardiff University.
