WILLSON General Superintendent Washington Water Power Company,Spokane, Wash. We have constructed a sand drier arrangement whichtakes the sand from a storage bin, screens it, runs itthrough a rotary drier and then conveys it to a secondstorage bin. On the right in the illustration is shown the bucketconveyor, which carries the sand from the receiving bin. LARGE CAPACITY SAND DRIER OF WASHINGTONWATER POWER COMPANY under the track to a hopper over the firebox. The sandis screened through a rotary screen, and it then goesthrough a chute and into the end of the cylinder whichprotrudes into the firebox. The latter is large enoughfor old track ties to be used as fuel without being the firebox the sand passes through a riveted steelcylinder 15 ft. long and 18 in. in diameter. This cylinderis patterned after a cement kiln. It is slightly tilted,sloping away from the firebox, and has blades ar- 908 ELECTRIC RAILWAY JOURNAL [Vol. 50, No. 20 ranged so that as the cylinder revolves the sand israised to the upper side of the tube and then drops backagain. As the cylinder forms a flue between the firebox andthe chimney, the hot air and gases come into immediatecontact with the sand and not only dry it but also removeall clay and vegetable matter, this being dried to dustand carried up the chimney.
