Embodiment 1

[0048] In the first step, 30 parts by weight of nitrogen, phosphorus and potassium fertilizers are taken, pulverized, passed through a 40-mesh sieve, and set aside.

[0049] In the second step, adding coal and coal gangue to the first step product through micro-mineral separation technology to obtain a particle diameter of 500 microns containing ultrafine mineral particles containing trace elements 50 parts by weight, humic acid 2 parts by weight, through 15 parts by weight of biochemically treated animal feces, mixed and fermented for 100min, the reaction temperature is 40°C,

[0050] In the third step, 3 parts by weight of biochemically treated seaweed is added to the product in the second step, and after stirring and mixing evenly, the material is sent to a disc granulator for granulation, and the granulated particles are finally sent to a drum dryer for drying. Drying at a temperature of 80°C, and at the same time, the material is rubbed against the drying cylinder for sec...

Embodiment 2

[0053] In the first step, 50 parts by weight of nitrogen, phosphorus and potassium fertilizers are taken, pulverized, passed through a 40-mesh sieve, and set aside.

[0054] In the second step, adding coal and coal gangue micro-mineral separation technology to the first step product is 40 parts by weight of particles of ultrafine minerals containing medium and trace elements with a particle size of 100 microns, 3 parts by weight of fulvic acid, seaweed 7 parts by weight of the activation liquid, stay in the fermenter for 100min, and the fermentation temperature is 35°C.

[0055] The third step is to mix the product of the first step and the product of the second step. After mixing evenly, the material is sent to the disc granulator for granulation, and the granulated particles are finally sent to the drum dryer for drying at a temperature of 80°C. At the same time, the material is rubbed against the drying cylinder for secondary granulation.

[0056] In the fourth step, the d...

Embodiment 3

[0058] The first step is to take 35 parts by weight of animal feces materials that have been fertilized to kill parasite eggs, pulverize them, pass through a 40-mesh sieve, and set aside.

[0059] In the second step, adding coal and coal gangue to the first step product through the micro-mineral separation technology is 60 parts by weight of ultrafine mineral particles containing trace elements in 20 microns, mixed with 3 parts by weight of organic chelating agent EDTA 200min, so that chemical chelation reaction occurs.

[0060] The third step is to stir the product of the first step and the product of the second step, add 2 parts by weight of black humic acid and mix evenly, then mix it and send it to the disc granulator for granulation, and the granulated granules are finally sent to the drum for drying The dryer is dried at a temperature of 80°C, and at the same time, the material is rubbed against the drying cylinder for secondary granulation.

[0061] In the fourth step,...

Abstract

The invention discloses a compound fertilizer rich in mineral substances. The compound fertilizer rich in mineral substances comprises the following raw materials in percentages by weight: A, 10-80% of mineral particles which are separated from coal or coal gangue before combustion or chemical conversion of the coal or coal gangue; B, 0-10% of an organic chelating agent; C, 5-40% of animal dung/algae raw materials which are treated biochemically; and optional D, 5-50% of at least one of a nitrogen fertilizer, a phosphatic fertilizer and a potash fertilizer. The mineral particles are rich in at least one of B, Ca, Cl, Cu, Fe, Mg, Mn, Mo, S and Zn which are necessary secondary and microelements for growth of plants. Mineral wastes in the coal chemical industry can be utilized economically and efficiently. The invention further discloses a preparation method of the compound fertilizer rich in the mineral substances.

Description

technical field [0001] The invention belongs to the field of fertilizer industry, and in particular relates to a compound fertilizer rich in minerals and a production process thereof. Background technique [0002] Fertilizer is the food of crops. my country is one of the countries with the largest consumption of chemical fertilizers. It accounts for 8% of the world's arable land, but uses about 30% of the amount of chemical fertilizers. Due to excessive or unreasonable fertilization, the input-output ratio has decreased and increased. Cost of production. In addition, the excessive use of chemical fertilizers has also brought about a series of problems: [0003] (1) Soil compaction [0004] Long-term single application of chemical fertilizers will cause soil acidification, kill bacteria in the soil, and humus cannot be replenished in time, which will cause soil compaction. After excessive nitrogen fertilizer is applied to the soil, the nitrogen supply of microorganisms incr...
