Below the 32' level, extensive deposits of the excellent sand and gravel were present, hut unfortunately elay strata ran through this entire lower section. action" which is sim ilar to the effect obtained by rubbing a handful of peb bles together betw een the palm s in a bucket of water. The H ardinge Scrub ber installed was an 8' diam eter x 48" cylinder unit with a 6' x 6' dew atering screen. The problem then, in order to con tinue operation, was to find a suitable washing device to elim inate the clay, which when wet is very sticky and difficult to wash and process. The solution was found in a H ardinge Conical Scrubber. The scrubber con sists of a conical shell like that of the well-known H ardinge Conical M ill, dis charging into a cylindrical dew atering screen which is fastened to the dis charge end of the scrubber and rotates with it. Internal liners and special lift ing flights create a turbulent "m ass About 30% to 33% of the total raw m aterial entering the entire plant passes through the H ardinge Scrubber. Usual water requirem ents for a scrub ber of this type are 2.5 to 3.0 G.P.M . per ton per hour of feed. Now in full operation, the H ardinge unit has ful filled expectations in regard to quality of output, sim plicity of operation, tonnage handled, m echanical aspects and its overall econom y of operation. The sand and gravel as now processed in the new w ashing plant is m aking an excellent product, one that m eets every federal, state and local specification.

See how flexible it is -- and how it straightens out without dam age. The secret is in the braided fabric construction -- o patented Tuffy feature! Scores of wires are stranded into 9 parts, then machine woven into an interlaced wire fabric entirely unlike conventional wire rope slings. Even cutting one of the 9 parts does not result in stranding. And eye splices develop up to 95% of the fabric strength. 11 Types of Tuffy Slings if none of the 11 factory packaged Toffy Sling types exoctly meet your rfeeds, Union W ire Rope engineers will develop one thot does. Toffy Slings are proof-tested to twice sofe working load. The Safe working load is stamped on o metal bond attached to each sting. If you hove your own rigging loft# Tuffy braided fabric is available by the reel.
