Abstract
An apparatus for testing the permeability of shredded elastomeric material which contains a vessel, a bed of tire chips in the vessel, and a fluid inlet which communicates with a first fluid outlet and a second fluid outlet through the bed of tire chips. The first fluid outlet is provided with a cap for optionally preventing fluid flow through it. The second fluid outlet is higher than both the fluid inlet and the first fluid outlet. A plate located above the bed of tire chips is used to compress the tire chips.
Claims5
An apparatus for testing the permeability of shredded elastomeric material comprised of a vessel and a bed of tire chip material disposed within said vessel, wherein said apparatus is comprised of:
- (a) a fluid inlet, a first fluid outlet, a second fluid outlet, and means for preventing the flow of fluid through said first fluid outlet, wherein:
- 1. said second fluid outlet is disposed above both said fluid inlet and said first fluid outlet, and
- 2. said fluid inlet communicates with each of said first fluid and said second fluid outlet through said bed of tire chip material;
- (b) a fluid conduit for providing liquid to said vessel through said fluid inlet;
- (c) means for varying the head of said fluid provided to said fluid conduit;
- (d) a plate for varying the compression of said bed of tire chip material, wherein said plate is disposed within said vessel;
- and
- (e) means for determining the flow rate of fluid passing through said bed of tire chip material.
