Detailed Product Description

 

Pellet Binder (Attapulgite Gray)

Description

Pellet Binder is made from a kind of clay mineral with the exact product name Attapulgite Gray. Attapulgite is a kind of crystalloid hydrous magnesium-aluminum silicate mineral, having a special laminated chain structure in which there is a crystalline lattice displacement existed. Thus it makes the crystals contain uncertain quantities of Na+, Ca+, Fe3+ and Al, and present in the shape of needles, fibers or fibrous clusters. Attapulgite has very good colloidal properties such as: specific features in dispersion, high temperature endurance, salt and alkali resistance, and also high adsorbing and de-coloring capabilities. Furthermore, attapulgite has certain plastic and adhesive characters. Its ideal molecular formula is:

Mg₅Si₈O₂₀(HO)₂(OH₂)₄₄H₂O.

The structure is somewhat between laminated and chain structure. Attapulgite looks like soil, and compact blocks which are found in the sedimentary rocks and the weathering crust. Attapulgite are white, hoar, caesious or celadon, or with some dim mercerization in color. The clay of attapulgite is fine and a bit greasy smooth, light in weight, crispy, and the fractured surface is like shells or in irregular shapes. Attapulgite has strong ability to absorb water. When it is wet, attapulgite shows plastic and adhesive properties; and when it gets dry,attapulgite does not shrink much and does not show cracks. When it is soaked in water,attapulgite collapses. The suspending liquid does not create soliquids and precipitates, when meeting electrolytes.

 

Characteristic

Selectively mined and processed attapulgite gray for pellet binder have a very high dispersion viscosity and API yield. The products processed from naturally occurring mixtures of attapulgite gray show especially high dispersion viscosity, high API yield, and extremely low grit.

 

Usage

In the area of livestock feed, attapulgite gray is mostly used as pellet binder. It can improve  the animals metabolism and the feeds efficiency, so that to increase the appetite of livestock to quicken the growth and reduce the feed cost. Meanwhile, the high adsorbability can also make the effect of feed sterilization by adsorbing bacillus. And in the area of  feeding fish, because of attapulgite grays low density and long term sedimentation in the water, it can highly increase the eating time of the fish to save feedstuff.

Physical analysis results of attapulgite gray

Toxicological test result of the attapulgite gray:

Both local Municipal Sanitation and Antiepidemic Station and Municipal Foodstuff Research Institute have carried out "The Comprehensive Sanitation and Safety Assessment on the Attapulgite Gray, a Natural Foodstuff Processing adjuvant". Their test results are as follows: Such heavy metals as arsenic, lead and mercury are not detectable in the attapulgite gray product, while total iron, sulfates, chlorides, nitrites, etc. are within the limits called for by the standards for processing adjuvant concerned. The tests on the content of the natural radioactive nuclide ²³⁸V,²³²TH,²²⁶Ra,⁴⁰K, and the natural R radiation dosage at the surface of the mining area show that in the original ore and in the product those figures are lower than that in the natural background value, therefore they are within the normal range. The Ames test reveals negative results and there is no positive reaction on the micronucleus incidence rate of the polychromatic erythrocytes in the bone marrow chromosome of mice. The max non-reaction dosage to animals is 9,909.01mg/kg, showing that the test material is very safe to the health of humans and animals.
