Drill Rig Rotary Splitters (2 replies and 1 comment)

I've been looking into the options for rotary splitters for RCP sampling and rmy bit of net searching turned up three on the market at the moment that look to be correct in terms of sampling theory. These are the Progradex ( see http://www.progradex.comm or the Sanvic Rota Port http://mining.sandvik.com/en/products/equipment/exploration-drill-rigs/sampling-systems/rotaport-cone-splitter and the Mtzeke http://www.metzke.com.au/products/drill-sampling-equipment/sampling-splitters/item/metzke-splitter.html I'd be interested to hear from users (rather than vendors) of these splitters as to how well (or not) they perform under production conditions. I'd also be interested to hear how they perform against the traditional dump box and tiered splitter systems.  Rotary splitters for RC sub sampling - what works best (assume dry ground)

I would also be interested with how the "internal water nozzles for cleaning" work on the Metzke system. In dry conditions (blow-down valves are good to maintain dry drilling), my worry would be wetting the inside of the splitter and then getting a build-up of material could be an issue.

How does the Metzke one work as I've not come across this one before? The website is pretty sparse on detail.

It's a rapidly spinning stream that sprays outwards to cylinder than the stream falls through sampling chutes. This overcomes the problem with getting many increments from the rotating stream and ensures the splits have very similar mass. I'm still thinking about the correctness of the method but I think it is OK. Metzke have some data that support the correctness of the split - suggest you give them a call and have a look - would be interested to hear your opinion.
