Abstract
The present invention provides granular potassium ammonium phosphate and a production method thereof, which belongs to the technical field of a granulation method of fertilizers. The water solution of saturated carbamide accounting for 4 to 10% of the quantity of powdery potassium ammonium phosphate to be granulated is uniformly mixed with the powdery potassium ammonium phosphate, and a product is obtained with a conventional granulation method. The strength of the granular potassium ammonium phosphate produced with the method is moderate, the granular potassium ammonium phosphate can be used as basic fertilizers and can also be used as additional fertilizers, a fertilizer effect is lasting, and the granular potassium ammonium phosphate can be suitable for mechanized operation.
Description
The present invention relates to a kind of prilling process of fertilizer, particularly binding agent in the granulation process.
Potassium-ammonium phosphate claims ammonium potassium dihydrogen phosphate again, is Powdered fertilizer always, can only use the foliage-spray of doing crop, and fertilizer efficiency period is short, also is not suitable for the mechanize production operation, can not satisfy needs of society.People once attempted to carry out granulation, but because of production technique particularly binding agent select improper always failing to achieve one's goal.
The objective of the invention is to deficiency at the powder potassium-ammonium phosphate, a kind of production technique of producing granular potassium ammonium phosphate is provided, producing the granular potassium ammonium phosphate product that reaches certain intensity, and then satisfy society and the potassium-ammonium phosphate product is strengthened fertilizer efficiency, the convenient needs that use.
Technical scheme of the present invention is:
A kind of method of producing granular potassium ammonium phosphate is characterized in that, adds saturated aqueous solution of urea by 4～10% (weight) of the weight of powdered acid potassium ammonium, stirs, enter then after the tablets press granulation commonly used product.The granular potassium ammonium phosphate that utilizes this method to produce, it is shaped as spherical (oblate spheroid shape or spherical shape) or strip, and its granularity (diameter) is 2～5mm, is preferably 2.5～4.5mm.
The present invention is owing to select for use aqueous solution of urea as adhesive for granulating, obtained beat all effect, can produce sphere or stripe shape particle as required, intensity reaches 6～12 newton, and to each nutrient content free of losses, the granular potassium ammonium phosphate of producing can utilize machinery to go deep in the soil and that nutrient is scattered and disappeared is few in granulation process, and the fertilizer efficiency time is long, both can make base fertilizer and also can topdress, and can reach goal of the invention fully through producing as a trial and trying out.
Be described further below in conjunction with embodiment.
Embodiment 1, takes by weighing saturated aqueous solution of urea by 4% (weight) of the weight of the Powdered potassium-ammonium phosphate of desiring granulation, pours in the potassium-ammonium phosphate of desiring granulation to mix, again the routine of falling people tablets press granulation and must product.
Embodiment 2, by 10% (weight) of the weight of the Powdered potassium-ammonium phosphate of desiring granulation take by weighing saturated aqueous solution of urea pour in the potassium-ammonium phosphate of desiring granulation evenly mixed, pour conventional tablets press granulation again into and product.
Embodiment 3, by 7% (weight) of the weight of the Powdered potassium-ammonium phosphate of desiring granulation take by weighing saturated aqueous solution of urea liquid pour in the potassium-ammonium phosphate of desiring granulation evenly mixed, pour conventional tablets press granulation again into and product.
Claims (3)
1, a kind of granular potassium ammonium phosphate is characterized in that, it is shaped as spherical or granular, and its granularity is 2～5mm.
2, a kind of method of producing granular potassium ammonium phosphate is characterized in that, 4～10% (weight) of pressing the weight of the Powdered potassium-ammonium phosphate of desiring granulation take by weighing aqueous solution of urea, mixes with the Powdered potassium-ammonium phosphate of desiring granulation, uses conventional tablets press granulation again.
3, the method for production granular potassium ammonium phosphate according to claim 2 is characterized in that, described aqueous solution of urea is bag and aqueous solution of urea.
