Example Embodiment

Specific embodiment one

[0021] The raw materials in the embodiments of the present invention come from the Jingzhou area of ​​Hubei.

[0022] 45 parts of phosphate rock powder, 45 parts of dolomite, 5 parts of serpentine, 5 parts of silica, after being crushed, are loaded into the feeding car and put into the high temperature melting furnace with a hoist. The hot air from the hot blast furnace is sprayed into the blast furnace through the tuyere to make the temperature in the high temperature zone reach about 1000℃. After the materials are fully calcined and melted in the furnace, calcined for 5 hours, the melt is discharged from the discharge port, and the gauge pressure is 0.2MPa The water jet makes it extremely cold, solidifies and breaks into fine particles and flows into the water quenching tank. The dried semi-finished product is then sent to the ball mill for fine grinding, and the fineness is required to pass 80 mesh sieve above 80%. The nutrient content of the product, ...

Example Embodiment

Specific embodiment two

[0023] The raw materials in the embodiments of the present invention come from the Jingzhou area of ​​Hubei.

[0024] 90 parts of phosphate rock powder, 5 parts of dolomite, and 5 parts of magnesite, after being crushed, are loaded into the feeding car, and put into the high-temperature melting furnace with a hoist. The hot air from the hot blast furnace is sprayed into the blast furnace through the tuyere to make the temperature in the high temperature zone reach about 1300℃. After the material is fully calcined and melted in the furnace, calcined for 1 hour, the melt is discharged from the discharge port and sprayed with 0.1MPa water. It is extremely cold and solidified and broken into fine particles to flow into the water quenching tank. The dried semi-finished product is then sent to a ball mill for fine grinding. The fineness is required to pass a 100-mesh sieve above 50%. Product nutrient content, phosphorus pentoxide (P 2 O 5 ) Content 10%, effecti...

Specific embodiment three

[0025] The raw materials in the embodiments of the present invention come from the Jingzhou area of ​​Hubei.

[0026] 49 parts of phosphate rock powder, 50 parts of dolomite, and 1 part of olivine, after being crushed, are loaded into the feeding car, and put into the high-temperature melting furnace with a hoist. The hot air from the hot blast furnace is sprayed into the blast furnace through the tuyere to make the temperature in the high temperature zone reach about 3000℃. After the material is fully calcined and melted in the furnace, calcined for 3 hours, the melt is discharged from the discharge port and sprayed with 0.5MPa water. It is extremely cold and solidified and broken into fine particles to flow into the water quenching tank. The dried semi-finished product is then sent to a ball mill for fine grinding. The fineness is required to pass through a 160-mesh sieve. Product nutrient content, phosphorus pentoxide (P 2 O 5 ) Content 20%, effectiv...

Abstract

The invention discloses a natural mineral fertilizer containing nano silicon and a manufacturing method thereof. The method comprises the following steps: mixing the following raw materials in parts by weight: 45-90 parts of ground phosphorite, 5-50 parts of dolomite and 1-10 parts of assistant, totaling 100 parts; and grinding, stirring, carrying out high-temperature calcination to activate the mixture, quenching with water for shock cooling, and pulverizing the product to obtain the fertilizer. The fertilizer comprises the following effective components: 10-20% of phosphorus pentoxide, 5-30% of effective calcium, 10-28% of effective silicon and 5-15% of effective magnesium; and the nano silicon accounts for 30-80% of the effective silicon. The natural mineral fertilizer containing nano silicon fully and effectively utilizes the low-grade phosphate ores in China, provides secondary and minor elements for crops, regulates and improves the crop growth mechanism, regulates the pH value of the soil, improves the soil structure, improves the physicochemical properties and biochemical properties of the soil, enhances the availability of the fertilizer, reduces the fertilizer consumption, and prevents the crops from absorbing heavy metals.

Description

technical field [0001] The invention relates to the technical field of mineral fertilizer production, in particular to a natural mineral fertilizer containing nano-silicon and a preparation method thereof. Background technique [0002] my country has a large population but little arable land. China uses 7% of the world's arable land to feed 22% of the population, but uses 35% of the world's chemical fertilizers. Continuous planting and continuous cropping and excessive application of chemical fertilizers have become a predatory resource development, resulting in a huge waste of resources. Not only is it difficult to increase food production, but it also destroys the internal structure of the soil, causing soil compaction, soil quality deterioration, and soil fertility. The environmental pollution caused by over-industrialization has caused a serious situation of heavy metal soil pollution; the quality of crops has declined, and the safety of agricultural products has serious...
