Abstract
The invention aims to provide a preparation technology of composite bentonite. The preparation technology comprises the following steps: mining a bentonite raw material from a bentonite mine firstly; then drying the bentonite raw material until the moisture is smaller than 15 percent; milling, and uniformly adding a composite bentonite additive in the bentonite before milling; drying by virtue of a three-channel rotary type drying oven until the moisture is smaller than 8 percent, thereby obtaining a final product. By virtue of adopting the preparation technology, the whole step is simple and easy to operate, and twice drying is adopted; as the composite bentonite additive is added after the first drying, and then milling mixing is carried, the colloid index of the prepared composite bentonite is increased by 15 percent, the dosage of the bentonite is lowered, and the preparation technology is suitable for production.
Description
Technical field
The present invention relates to the manufacture field of natural montmorillonite, relate in particular to a kind of composite bentonite preparation technology.
Background technology
Wilkinite is the nonmetallic minerals taking montmorillonite as essential mineral composition, some positively charged ion that the laminate structure forming due to the de-stone structure cell of door exists, as Cu, Mg, Na, K etc., the effect of these positively charged ions and montmorillonite structure cell is very unstable, easily by other cationic exchange, therefore there is good ion exchangeable.Abroad in 24 field 100Duo Ge departments of industrial and agricultural production, apply, have more than 300 product, thereby people are referred to as " omnipotent soil ".
My company works out a kind of composite bentonite additive, its main component is Microcrystalline Cellulose, magnesium oxide, high-temperature explosion-proof machine etc., its Main Function is the colloid index that has obviously improved product, reduce the more than 1/3 of bentonite material consumption, make bentonitic performance become more superior, added to step in wilkinite very important, therefore need to design a kind of technique that is applicable to preparing composite bentonite and just seem very necessary.
Summary of the invention
The invention provides a kind of composite bentonite preparation technology, solved the problem occurring in background technology, this preparation technology is simply effective, the composite bentonite excellent performance making.
The object of this invention is to provide a kind of composite bentonite preparation technology, comprise the following steps:
Step 1: from bentonite ore exploitation bentonite material;
Step 2: the bentonite material of exploitation is dried with drying kiln until moisture is less than 15%;
Step 3: dry and carry out abrasive dust later, the fineness of abrasive dust is 150 ~ 200 orders is added composite bentonite additive uniformly before abrasive dust in wilkinite;
Step 5: the wilkinite that added composite bentonite additive is dried to moisture through the rotary dry case of triple channel and is less than 8%, just can obtain final product.
Further improve and be: the temperature of described drying kiln is 280 ~ 320 DEG C, and the temperature of the rotary dry case of triple channel is 70 ~ 95 DEG C.
Further improve and be: described composite additive and bentonitic mass ratio are (15 ~ 50): 100.
Further improve and be: described composite additive includes Microcrystalline Cellulose, magnesium oxide and high-temperature explosion-proof agent.
Beneficial effect of the present invention: first dry moisture to 15% after the exploitation of this technique, after adding again composite bentonite additive, carry out abrasive dust, after abrasive dust, be dried to again moisture to 8%, whole step is simply effectively easy to operate, adopt the technology of twice oven dry, add composite bentonite additive and carry out abrasive dust mixing again after drying for the first time, prepared composite bentonite colloid index improves 15%, reduce bentonitic consumption, in being applicable to produce.
