The Rowell Flowability Tester is used to determine the flowability of molding sand by testing the sands ability to tightly compact into deep pockets on pattern. Sands that do not have adequate flowability typically result in low mold density and can be the cause of casting defects.

The tester is a specially designed pattern inserted into a specimen tube that is filled with sand and rammed with a Sand Rammer (Model 42100).  The resulting sand specimen is then placed onto a specially designed cradle where mold hardness readings are taken at different locations on the specimen.   Rowell flowability can then be calculated as the percent difference in hardness between the top and bottom of the specimen.

Components Included: Pattern and Specimen Cradle
