I'm transcribing some old hand written reports about the dressing plant for a mine I'm interested in and I'm having trouble deciphering some of the specific names of the kit being described.
The words between the ?? below are the ones I'm dubious of or would like to know exactly what they were. Any suggestions or information gratefully received.

from which it passes to a ?Boxler? knapping stonebreaker

followed by a small classifier and a ?spitz kasten?.

The first spigot of the ?spitz kasten? feeds to a ?hurhrig? vanner.

"Spitz Kasten" I'm pretty sure is transcribed correctly but what is it- I can find references on the web that imply its some kind of classifier but does anyone know how it worked? "Boxler" and especially "hurhrig" are presumably company names but I'm not at all sure what the word might be.

Cheers

'A Spitzkasten in its simplest form consists of an inverted pyramidial box rectangular in plan, and having an aperture at the apex'.
A stream of pulp is allowed to flow slowly in at one side of the box, and the particles capable of falling through the belt of water are deposited. You really need to read the full description & see the drawings to fully understand!
That was taken from 'The Dressing of Minerals' by Henry Louis 1909, a cracking bedtime read - over 540 pages of sizzling mineral dressing action!!!
I can try to scan the relevent pages if you wish?

For Huhrig, I think you need Luhrig Vanners - a type of shaking table, also decribed in Louis.

Grey Gold (Greenside Mine) by Sam Murphy has details of the Luhrig Vanners & also the Spitzkasten used there, page 221 shows the Luhrig Vanner,
and pages 207 & 284 onwards describe the Spitzkasten and their positions in the Low mill.

Discovering Lost Mines by Peter Naylor also has a small drawing of the Spitzkasten (p48, Greenside)

Boxler, I haven't found yet, but i'm looking!

Its old Henry Louis himself who wrote this report about 1919, I'd love a copy of the relevant bit if you could manage it Thanks
