Problems solved by technology

The instant granular potassium fertilizer of the present invention is mixed and granulated by adding some inorganic substances with a large expansion coefficient and powdery potassium fertilizer, which solves the problem that farmers have too much dust to fertilize, and solves the problem of fertilizer dissolving in the soil on the other hand. Slower, slow absorption by crops

Embodiment 1

[0025] (1) put bentonite and potassium sulfate into two feed bins respectively and put in the material by controlling the metering scale, and put the material into the ball mill with bentonite and potassium sulfate in a ratio of 1.5:8.5 for mixing and grinding for 30 minutes;

[0026] (2) The mixed material is conveyed to the granulation drum through the belt, and the water is atomized and sprayed to the surface of the fertilizer through the atomizing nozzle to form potassium sulfate into particles;

[0027] (3) Send the granulated potassium sulfate into the drying drum for drying, and then sieve and pack the fertilizer after drying.

[0028]

Embodiment 2

[0030] (1) Put the modified soil and potassium chloride into two silos respectively, and put the materials into the ball mill with the ratio of 0.5:9.5 to the modified soil and potassium chloride for mixing and grinding. 30min;

[0031] (2) The mixed material is conveyed to the granulation drum through the belt, and the water is atomized and sprayed to the surface of the fertilizer through the atomizing nozzle to form potassium chloride particles;

[0032] (3) Send the granulated potassium chloride into the drying drum for drying, and then sieve and pack the fertilizer after drying.

[0033]

Embodiment 3

[0035] (1) Put the attapulgite and potassium sulfate into two silos respectively to put in the materials by controlling the metering scale, and put the materials into the ball mill with the attapulgite and potassium sulfate in a ratio of 1:9 for mixing and grinding for 10 minutes;

[0036] (2) The mixed material is conveyed in the granulation drum through the belt, and the mass concentration is 0.5% PVA aqueous solution, which is atomized and sprayed to the fertilizer surface by the atomizing nozzle to make potassium sulfate form particles;

Abstract

The invention provides a round granular potash fertilizer with instant characteristic and a preparation method, the round granular potash fertilizer with instant characteristic is formed by combining a component A and a potash fertilizer, the ratio of the component A to the potash fertilizer is (0.1-2): (8-9.9), and the component A is an inorganic disintegrating agent with an expansion coefficient greater than 1. The preparation method comprises the following steps: putting the component A and potash fertilizer powder into different bins, putting the component A and the potash fertilizer powder into a mixer according to a ratio of (0.1-2): (8-9.9), and mixing for 10-30 minutes, the component A being an inorganic disintegrating agent with an expansion coefficient greater than 1; after mixing, conveying the mixture to a granulation roller or a disc through a belt or an auger to be subjected to auxiliary agent spraying granulation; and drying, screening and packaging after the granulation stage. The product provided by the invention can provide effective nutrients for crops, is convenient for large-scale application, and has high application value. The product facilitates large-scale mechanical fertilization, saves a lot of manpower and material resources, and facilitates rapid absorption of crops.

Description

technical field [0001] The invention belongs to the technical field of agricultural chemical fertilizers, and relates to a granular fertilizer used in agriculture and a preparation method, in particular to a round granular potassium fertilizer with instant properties and a preparation method. [0002] technical background [0003] When fertilizing, powdery potassium fertilizer and irregular potassium fertilizer are very inconvenient for mechanical fertilization. If the powdered potassium fertilizer is applied mechanically, it will cause excessive dust, and if the irregular granular potassium fertilizer is applied mechanically, it will cause mechanical jamming. The round granular potassium fertilizer will solve this problem and greatly improve the fertilization efficiency. [0004] Compared with other similar types of extruded or round granular potassium fertilizers, it is more convenient to add related components, making the potassium fertilizer disintegrate into powdery pot...
