GENERAL INFORMATION

Typical Analysis: 25% Attapulgite Clay

Uses:

• Assures optimum thickening and suspension of feed liquids.
• Can be used in either cold mix or hot mix plants.
• The use of the pre dispersed clay decreases mixing time which will increase production ad lower production costs. This product provides maximum viscosity from clay in addition to a longer lasting more stable product.

Storage:

A tank free of contamination of other feeds and other raw materials must be used. Liquid Clay can be stored in any container that would otherwise be suitable for water. Tanks can be mild or stainless steel, polyethylene type, fiberglass, expandable bladder, horizontal or vertical. Interior lined or non-steel tanks are preferred but not required. Access to the interior of the tank is desirable should clean-out be necessary.

Because liquid clay exhibits thixotrophy, the slurry remains viscous at rest but becomes very fluid under shear. Thus, it is recommended that the storage tank be equipped with some form of agitation. Mechanical propeller, air sparger, or pumped re-circulation are alternatives. Of the three, pumped re-circulation is best and probably the most convenient since a slurry pump placed between the storage tank and the mixing tank can serve the dual role as a recirculation and delivery pump. In this configuration, the outlet port should be as low as possible on the tank with the recirculation pipe entering the top.

Advantages:
The suspension feed market has been seeking for some time a dustless, free-flowing, gelling medium that will save time and money in the preparation of suspensions. A "liquid clay", made by dispersing in water a specially selected attapulgite clay, would not only satisfy the above, but would also exhibit the following advantages for the suspension manufacturer:

1. Behave as a pumpable fluid.
2. Reduce labor costs in handling bags of dry clay and increase production time.
3. Drastically reduce clay unloading times.
4. Eliminate dry-flow problems and clay hang-up in machinery.
5. Create a faster suspension because clay is pre dispersed.
6. Create a more stable suspension because the pre dispersed clay is degritted - all sand having been removed.
7. Reduce capital outlays for high-shear equipment.
8. Comply with OSHA and EPA standards as regards airborne dusts surrounding mixing plants and worker safety.
9. No Dust
10. A better suspension.
