ABSTRACT:
A simple and rapid test, and an apparatus for use therein, is described for measuring the filtration, or drainage, characteristics of a fibrous slurry. The results obtained by this test are accurately reproduced in production size systems, e.g. a wet process for the manufacture of asbestos-cement products such as sheet or pipe. The test utilizes a portable, light-weight leaf filter and can be run in 2-3 minutes.
