Problems solved by technology

[0005] At present, the main problems in the research and development of silicon fertilizers are as follows: First, there is no granulation process in the process of making silicon fertilizers. During the application of powdered silicon fertilizers, the dust phenomenon is serious, and the dust sticks to the plants, and its alkaline substances cause damage to the plants. harm
Second, since the silicon fertilizer produced directly from water slag is alkaline, it is easy to cause nitrogen fertilizer to be converted into ammonia nitrogen volatilization loss during the application process. It must be used alone during use, which is inconvenient.
However, there is no report on the production of humic acid silicon calcium magnesium fertilizer

Embodiment 1

[0024] The water-quenched slag is naturally air-dried to a water content of 15% (mass fraction), and the dried water-quenched slag enters a ball mill for grinding to a size of 80 meshes, and then the ground powder and humic acid content are 75% (mass fraction). fraction) of the humic acid raw material (purchased from Xinjiang Shuanglong Humic Acid Co., Ltd.) is mixed uniformly to form mixture A in a mass ratio of 2: 1.5, and then in mixture A, an amount of 5% binder ( bentonite), stir and mix evenly, and then granulate on the fertilizer granulator. During the granulation process, spray water according to 15% of the mass of the mixture A to form granular fertilizer. The particle size of the fertilizer is controlled at 2-4mm, and finally dried Then make humic acid silicon calcium magnesium fertilizer.

[0025] Product fertilizer characteristics: The finished fertilizer is neutral, PH is 7.0, and the nutrient content is SiO 2 20%, CaO 20%, MgO 10%, organic matter 35%, the ferti...

Embodiment 2

[0029] The water-quenched slag is naturally air-dried to a water content of 20%, and the dried water-quenched slag is ground in a ball mill to a particle size of 100 mesh, and then the ground powder is mixed with humic acid content of 75% (mass fraction). The phytic acid raw materials are mixed uniformly at a mass ratio of 2:1 to form a mixture A, then add 10% of the mass of the mixture A binder (kaolin) to the mixture A, stir and mix evenly, and then granulate on a fertilizer granulator. In the process, water is sprayed according to 10% of the mass of the mixture A to form a granular fertilizer, the particle size of the fertilizer is controlled at 2-4mm, and finally the humic acid silicon calcium magnesium fertilizer is obtained after drying.

[0030] Product fertilizer characteristics: The finished fertilizer is neutral, with a pH of 7.5 and a nutrient content of SiO 2 22%, CaO 23%, MgO 11%, organic matter 30%, the fertilizer is black granular.

Embodiment 3

[0032] The water-quenched slag is naturally air-dried to a water content of 25%, and the dried water-quenched slag is ground in a ball mill to a particle size of 80 mesh, and then the ground powder is mixed with humic acid content of 80% (mass fraction). The phytic acid raw materials are mixed uniformly to form mixture A in a mass ratio of 2: 1.3, then add 8% binder (bentonite) of mixture A quality in mixture A, stir and mix uniformly, then granulate on a fertilizer granulator, During the granulation process, water is sprayed in an amount of 12% of the mass of the mixture A to form a granular fertilizer, and the particle size of the fertilizer is controlled at 2 to 4 mm. Finally, the humic acid silicon calcium magnesium fertilizer is obtained after drying.

[0033] Product fertilizer characteristics: The finished fertilizer is neutral, with a pH of 7.5 and a nutrient content of SiO 2 21%, CaO 22%, MgO 10%, organic matter 32%, the fertilizer is black granular.

Abstract

The invention discloses a humic acid silicon calcium magnesium fertilizer and a production method thereof. The production method comprises the following steps: carrying out natural air drying on water quenching slag until the water content reaches 15-25%; milling the dried water quenching slag in a ball mill to 80-100 meshes; evenly mixing the milled powder and a humic acid raw material, of whichthe humic acid content is 75-80 wt%, in a mass ratio of 2:(1-1.5) to form a mixture A; adding adhesive, which accounts for 5-10 wt% of the mixture A, into the mixture A, and evenly mixing; granulating on a fertilizer granulator, wherein the water, which accounts for 10-15 wt% of the mixture A, is sprayed on the mixture A to form the granular fertilizer, and the granularity of the fertilizer is 2-4mm; and finally, baking to obtain the humic acid silicon calcium magnesium fertilizer. The humic acid silicon calcium magnesium fertilizer has the advantages of low production cost, high available nutrient content, high crop utilization ratio, low environmental risk and strong soil pertinence, is convenient for field application, and can be popularized and applied in crop production.

Description

Technical field: [0001] The invention belongs to the field of fertilizer manufacturing, and in particular relates to a production method for producing humic acid silicon calcium magnesium fertilizer by using ironmaking blast furnace water quenching slag and humic acid as raw materials and the humic acid silicon calcium magnesium fertilizer produced by the method. Background technique: [0002] Water-quenched slag is also called blast furnace slag. It is the waste slag formed by water-quenching and quenching blast furnace slag in the process of iron-making by iron and steel enterprises. Its main components are: SiO 2 34.9%, CaO 36.8%, Al 2 o 3 11.3%, MgO 13.2%. [0003] The use of water-quenched slag as a fertilizer has a long history in Germany. At present, the main process of using blast furnace slag to produce silicon fertilizer in Germany is: crushing the blast furnace slag to a certain particle size and applying it directly, or crushing the blast furnace slag and mi...
