Definitions

  • the group of inventions relates to a method for producing mineral fertilizer and to mineral fertilizer obtained from industrial utilization products, namely from sunflower husk ash.
  • the fertilizer obtained from the sunflower husk ash can be used in household plots, in agriculture and forestry.
  • Sunflower husk ash can quickly reduce the acidity of the soil, which needs liming, so the ash is used as an alkaline fertilizer. It complicates the development of root and extra root rot, pathogens. Sunflower husk ash as a chlorine-free mineral fertilizer is produced by many enterprises [information can be found on the Internet at https://mariupol.flagma.ua/zola-luzgi-podsolnechnika-o2877649.html,
  • One of the methods to reduce the dust formation of bulk substances and fertilizers, in particular, is granulation.
  • Ash is an unplastic raw material that does not have astringent and finely divided materials. It is known that the smaller the size of the dust particles, the less their ability to wet. Wetting is prevented by the gas shell forming around small particles of ash. This circumstance makes it difficult to organize the process of granule formation at the initial stage of granule nucleation using water as a binding agent. The use of other binding agents instead of water negatively affects the chemical composition of the fertilizer.
  • the technical problem underlying this invention is the creation of granular fertilizer and a method for its production exclusively from powder of sunflower husk ash and water as a moisturizing component.
  • the sunflower husk ash is close to wood ash.
  • the fertilizer described in patent RU 2631073 (patent holder of Tekhnoservis LLC) obtained from wood ash by rolling in a plate granulator was adopted.
  • Fertilizer granules have a core (seed granulation) and a coating layer obtained by rolling wood ash on a plate granulator using water as a moisturizing component.
  • the particle size of the wood ash used is from a few microns to 0.01 mm.
  • the core of the granule is the screening of wood ash in the form of particles up to 1.5 mm in diameter obtained by sieving, that is, particles of slag, the so-called no-burn.
  • granular fertilizer from ash is a fertilizer of prolonged action, it slowly passes into a dissolved state, in which mineral substances can be absorbed by plants. Therefore, in personal subsidiary plots, when it is desirable to quickly increase crop yields, the use of ash with granules of 5-7 mm is unreasonably costly and therefore unacceptable.
  • pellet cores obtained from screenings are poor wetted and, accordingly, poorly enveloped by particles of wet ash, which leads to the fact that the adhesion forces of the core and the coating layer are low, and accordingly, the granules of the prototype in reality have a relatively low strength (2.0 MPa) and a significant spread in the value of this indicator.
  • the problem solved by the group of inventions is to expand the arsenal of technical means in the field of mineral fertilizers, namely, to create a new granular fertilizer with high consumer properties from the sunflower husk ash and the method for its production, devoid of the disadvantages of the prototype.
  • the inventive method allows to obtain a qualitatively new mineral fertilizer, the rounded granules of which are entirely (without the use of seed slag particles) formed from husk ash and have the desired properties - increased strength and at the same time set softening factor (the ratio of the strength of the granules in the dry state to the strength of the granules in a water-saturated state) , which leads to their more rapid destruction in the moisture contained in the soil (up to 0.5-3 years).
  • the problem in the first object of the invention (granular fertilizer) is solved in that the granular fertilizer consists of round granules, which are formed from agglomerated particles of sunflower husk ash moistened with water, have a nuclear-free structure, that is, they do not have a slag core and are formed without the use of seed particles. Moreover, they have a compacted surface layer.
  • the average strength of the granules is at least 4.0 MPa and a softening factor of 2.2-2.6.
  • the fertilizer contains nutrients for plants in the following ratio: P 2 O 5 - 3.26-7.89% of the mass , K 2 O - 32.5-44.8% of the mass , CaO - 9.5-15.4% of the mass , MgO - 7.5-15.6% of the mass , SO 3 - 11.1-13.5 mass%, Na 2 0 -1,3-1, 7% ma ss, SiO 2 - 1.5 to 2.1% by weight of trace elements, including Zn, Cu, Ba, Fe, V, Cr, Mn, Mo, Co, - not less than 2% of the mass .
  • composition of the granular fertilizer is fully consistent with the composition of the sunflower husk ash and varies depending on its initial composition. In turn, this depends on the soil of sunflower growth, fertilizers used, climatic conditions and other factors.
  • the fertilizer has fractions of granules with a diameter of 2-4 mm more than 80% of the total composition.
  • the problem in the second object of the invention (a method for producing granular fertilizer) is solved by the fact that the claimed method includes the formation of raw granules from sunflower husk ash with the addition of water, carried out in a mixer-granulator, and subsequent rolling of the raw granules on a plate granulator using water as a moisturizing component. This ensures the spontaneous rolling of granules across the side of the plate of a dish-shaped granulator.
  • any mixer granulator suitable for these purposes can be used. It is preferable to use in the first stage a rotary mixer-granulator with a paddle rotor.
  • the particle size is from a few microns to 0.01 mm.
  • the composition of the nutrients is given above.
  • Ash is loaded into a continuous rotary mixer-granulator, for example, an apparatus with a horizontal rotor blade.
  • the ash is wetted with water supplied through nozzles and forms a homogeneous mass.
  • the granulation process is carried out under the action of centrifugal forces with intensive exposure to the granulated mixture of blades of a rotating working body.
  • the turbulent movement of solid particles determined by the design of the rotor, ensures uniform distribution of the liquid phase between the ash particles in the entire volume of the moving material and high dynamic loads, resulting in the formation of raw granules of a given size.
  • the obtained raw granules do not have the type of marketable products, because have a rough surface with growths of small agglomerated particles of ash, which later (transportation, storage) crumble, and part of the granule again passes into a dusty state.
  • the raw granules are fed to a dish-shaped granulator plate, to which water is also fed through nozzles.
  • a dish-shaped granulator plate When rolling raw granules on a dish-shaped granulator, surface roughness is smoothed out and their density and granularity are increased.
  • the granules gain strength. Due to the fine dispersion of the starting material, the dried granules are capable of maintain a sufficiently high strength, the reason for which is the so-called “contact-condensation” intermolecular attraction forces, the level of which is proportional to the dispersion of the ash.
  • a granular fertilizer was obtained at the output, the granules of which have a fraction of 2-4 mm in diameter demanded by the mass consumer that exceeds 80% of the total volume, that is, increased uniformity of the dispersed composition of the granules.
  • the diameter of the granules it is possible to change the operating modes of the granulator and add ash to its plate.
  • Studies of the resulting product showed that the composition of the fertilizer for plant nutrients corresponds to the composition of the original husk ash (see above).
  • the granules have a rounded shape.
  • the sphericity coefficient is not less than 0.7-0, 8.
  • the charged granules have a nuclear-free structure, that is, they do not have slag cores, are formed without “seed particles”, which leads to a decrease in stresses in the contact zone during drying.
  • the average granular strength is at least 4 MPa, and in some cases reaches 4.7 MPa, which is 20-25% higher than the strength of wood ash granules.
  • the listed characteristics indicate that the granules, having got into moist soil, soften and transfer to the initial finely dispersed state (the state of the initial ash), and the water-soluble compounds that make up it begin to dissolve.
  • the entire granule decomposes as does not have a foreign core.
  • the sparingly soluble compounds are processed by microorganisms, which makes them suitable for use by plants.
  • An increase in the rate of release of nutrients and the transition to a form assimilated by plants leads to a more rapid increase in yield in the early stages of fertilizer application, which is important for its use in home gardens.
