CS225232B1 - Menufacture of mineral magnesium licks for feeding purposes - Google Patents

Description

The invention relates to a process for the production of mineral licks for feed purposes by decomposing magnesium oxide or magnesium carbonate or a mixture thereof with an equivalent amount of hydrochloric acid and subsequently adding the reaction mixture with other mineral components of importance in animal nutrition. To accelerate solidification of the reaction mixture and to improve the physical properties of the article, the reaction mixture is subjected to vibration at a specified frequency.

At present, mineral magnesium licks are produced by mixing magnesium oxide with a magnesium chloride solution; this basic mixture, similar to the so-called Sorell cement, is supplemented with other active substances and allowed to solidify after mixing.

This process has a number of drawbacks, consisting in the need to use magnesium oxide, which is obtained by an expensive thermal process, with some of the magnesium being used as a further product in magnesium chloride solution. The reaction of these substances - chloride and magnesium oxide - is only very slightly exothermic, the mixture is poorly heated and therefore there is a slight evaporation of water. The reaction does not release a gaseous component and therefore the product is not porous.

These disadvantages are overcome by the process of the present invention consisting in the decomposition of magnesium oxide or magnesium carbonate or a mixture thereof with an under equivalent amount of hydrochloric acid, whereby generating a considerable amount of heat produces the desired system - solution of magnesium chloride and solidification of the reaction mixture, even when supplemented with other minerals such as salts of phosphorus, calcium and microelements. Advantageously, the so-called magnesia flakes falling off during the manufacture of refractory ceramic materials can be used. Lovinite, Magnovite and contain a favorable ratio between oxide and magnesium carbonate, which leads to high production of reaction heat and carbon dioxide, which creates micro-products in the product.

The reaction mixture is subjected to vibration at a specified frequency, thereby accelerating solidification and reducing the consumption of hydrochloric acid.

Example 1

493.2 wt. parts by weight of magnesium drift and 88.2 wt. % of hydrochloric acid (37% by weight). The reaction proceeds for 5 minutes and then the other mineral components are added: 108 wt. parts of dicalcium phosphate, 351 wt. parts of feed salt, 64.7 wt. parts of plaster, 2t, 5 wt. parts by weight of zinc sulfate, 17.9 wt. parts by weight of manganese sulfate, 3.2 wt. parts by weight of copper sulfate, 0.6 wt. parts by weight of potassium iodide and 0.2 wt. parts of cobalt sulfate. The mixture is then homogenized for 2-3 minutes and 40.5 wt. parts of water and resuspend in 3 minutes. The wet mixture is dispensed into containers and placed on a vibration stand where it is subjected to high frequency vibration (50 cycles / sec) for 2 minutes. The obtained semi-solid compositions are stored in packages in shipping pallets for dispatch. Complete solidification occurs within 2-4 hours.

Example 2 225 232

120 wt. 22.5 wt. · The mixture is vigorously stirred for 5 minutes and then the other mineral components are added: 232.2 wt. parts of dicalcium phosphate 436.9 wt. parts of feed salt, 180 wt. parts of plaster,

4.4 wt. parts by weight of zinc sulfate, 4.4 wt. parts by weight of manganese sulfate, 2.0 wt. 0.1 parts by weight of copper sulfate; parts by weight of potassium iodide and 0.02 wt. parts of cobalt sulfate.

The mixture is then homogenized for 2-3 minutes and 52.5 wt. parts of water and mixed again within 2 minutes.

The wet mixture is placed in appropriate containers on a vibration stand where it is subjected to high frequency vibration (70 cycles / sec) for 2 minutes. The semi-solid composition obtained is stored in packages in shipping pallets for dispatch. Complete solidification occurs within 2-4 hours.

Example 3

302 parts by weight of magnesium oxide are introduced into the mixing unit and 105 parts by weight are added under vigorous stirring. parts by weight of dicalcium phosphate, 400 wt. parts of feed salt, 70 wt. gypsum parts and other components:

% by weight, parts of zinc sulfate, 16 wt. parts by weight of manganese sulfate, 3.0 wt. 0.5 parts by weight of copper sulfate; parts by weight of potassium iodide and 0.1 wt. parts of cobalt sulfate. The mixture is mixed for about 3 minutes and 38 wt. 4 min. The wet mixture is dispensed into containers and washed on a high frequency stool, where it is subjected to a high frequency vibration (80 cycles / sec) for about 2 minutes. The obtained composition is placed in semi-solid state in packages in shipping pallets for dispatch. Complete solidification occurs within 2-4 hours ·
