Several things they omitted. clean the material before feeding the concentrator. lots of clay it was present and the performance was reduced. Another thing was the clean water. Unfortunately, the Knelson concentrator doesn't have a driver to control the rpm. I prefer the Icon, but the feeding chocking the device and the miners decide themselves to install that Knelson concentrator. The gold grain size will demand the rpm to be used and no studies were made about it. We were dealing with Quartz veins and the alteration zone, not just quartz. The finer gold went out in the process
@@JhonnyLeon03080901 Thanks for comments Jhonny, I know sometimes its difficult to keep the best performance in Jungle sites ... but do you think that with fine gold recovery the rpm has to be at least slow ... such as 240 rpm, as per normal recommendation of the factory ? Also if I use a frequency control in the motor I may control the batch rpm ... don't you think? Thanks for all mate!!!
@@mapareja71 I had a meeting with personnel of GEKKO and they said me that it is better to connect another concentrator in the tail of the first one, to catch that gold that can't be collected in the first device.
@@JhonnyLeon03080901 Well sounds a nice advise and option also, many thanks for the experience exchange ... needing anything in Brazil just let know mate!
@@mapareja71 I'm interesting in ball mills because over here, in Guyana is hard to have information. I have friends in Peru, because I worked before in the mountains ( Ancash). I appreciate any input that you can provide me. Thanks in advance
Hi Jhonny thanks for your post .... Do you what would be the best RPM for this bowll rotation on this yellow Knelson concentrator ?
