Embodiment Construction

[0019] Referring to the drawings, a testing apparatus 10 is shown comprising a testing chamber 12 of generally cylindrical form. In the arrangement shown, the test chamber 12 takes the form of a hollow tubular member 14 within the lower end of which a table 16 is positioned, a fastening mechanism 18 is provided for releasably fastening the tubular member 14 Go to examination table 16. The inspection station 16 closes the end of the tubular member 14 and thus defines a container in which, in use, the material to be tested may be located. It should be understood, however, that this represents only one of a variety of possible designs from which test chamber 12 may be designed.

[0020] The apparatus 10 further comprises a powder handling device, hereinafter referred to for convenience as a compacting device 20, which can be introduced into the test chamber 12, can move axially along the length of the test chamber 12 and can also be driven for rotational movement around its axi...

Abstract

A test apparatus is described comprising a test chamber (12), a powder manipulation device such as a compaction device (20), and a drive arrangement (22) selectively operable to drive the compaction device (20) for axial movement and for rotary movement within or relative to the test chamber (12), the compaction device (20) preferably comprising at least one complete turn of a generally helical screw flight (26). Methods of use of the test apparatus are also described.

Description

technical field [0001] The present invention relates to a test device, and in particular to a test device intended for obtaining data representative of the properties of compacted or consolidated powder or granular material. In particular, the invention relates to a test apparatus suitable for achieving such compaction or consolidation, and to a method of operation thereof. The testing equipment may further be capable of performing tests to provide information about properties of the material being tested. Background technique [0002] Several devices are known for testing powders and the like. In one such device, a column of material to be tested is compacted within a mold or test chamber. The mold or test chamber is then removed and a load is applied to the compacted test material in order to determine how much load can be applied to the compacted test material before the column of material yields or breaks. This test is sometimes called an unconfined yield strength tes...
