EQUIPMENT MANAGEMENT As with any process equipment, wash plants require periodic operational and maintenance checks to optimize the machine's operation. Keeping the 'Class' Long-term operation and maintenance of your classifying tanks can be achieved by following five simple tips. by Tom Moore and Dave Schellberg and classifying tanks have been used for more than 50 years for refining glacial/ alluvial 'natural' and 'manufactured' sands and sand slurries. They have been used primarily in North America for three typical reasons: 1. Concentrating or 'scalping' water in a low-per- cent solids slurry for more efficient dewatering by downstream equipment; S 2. Removal of excess intermediate sand grain sizes to produce a uniformly graded product for many common construction sand specifi- cations; and Operation AGGREGATES MANAGER March 2012 in Classifying Tanks 3. The production of two controlled and one un- controlled sand product from a single feed. As with any process equipment, periodic operational and maintenance checks are rec- ommended to optimize a machine's operation. Your manufacturer's installation and mainte- nance manual can be used as a guide to allow the most efficient performance and yield of desired sand products. This type of sand tank is not a 'set it once and walk away' device, as sand feeds can vary due to 39
