Problems solved by technology

This kind of compound fertilizer production method has high pelleting rate (up to 70%), simple equipment operation, large working flexibility, convenient maintenance, eliminates the phenomenon of material sticking to the wall, reduces the labor intensity of workers, and greatly prolongs the service life of the equipment. and other advantages, but there are the following defects: (1) The proportioning ratio is very limited, such as high-nitrogen type compound fertilizer can hardly be produced; (2) The roller compound fertilizer is a quick-acting fertilizer with fast

Example Embodiment

[0019] Example 1

[0020] A selenium urea formaldehyde drum granulated compound fertilizer, comprising urea formaldehyde, potassium chloride, monoammonium phosphate, sodium selenite pentahydrate, moisture and ash, and each composition by weight is: urea formaldehyde 0.44, potassium chloride 0.25, phosphoric acid Monoammonium 0.17, sodium selenite pentahydrate 0.0187, moisture 0.03, ash 0.02. Among them, urea formaldehyde is synthesized from urea and formaldehyde at a weight of 2:3, and urea is selected as N-P 2 O 5 -K 2 O=46-0-0.

Example Embodiment

[0021] Example 2

[0022] A selenium urea formaldehyde drum granulated compound fertilizer, including urea formaldehyde, potassium chloride, monoammonium phosphate, sodium selenite pentahydrate, moisture and ash, each composition by weight: urea formaldehyde 0.38, potassium chloride 0.25, phosphoric acid Monoammonium 0.21, sodium selenite pentahydrate 0.0281, moisture 0.035, ash 0.0969. Among them, urea formaldehyde is synthesized from urea and formaldehyde at a weight of 2:3, and urea is selected as N-P 2 O5-K 2 O=46-0-0.

Example Embodiment

[0023] Example 3

[0024] A selenium urea formaldehyde drum granulated compound fertilizer, including urea formaldehyde, potassium chloride, monoammonium phosphate, sodium selenite pentahydrate, moisture and ash, each composition by weight: urea formaldehyde 0.74, potassium chloride 0.08, phosphoric acid Monoammonium 0.11, sodium selenite pentahydrate 0.0187, moisture 0.03, ash 0.02. Among them, urea formaldehyde is synthesized from urea and formaldehyde at a weight of 2:3, and urea is selected as N-P 2 O 5 -K 2 O=46-0-0.

Abstract

The invention relates to a fertilizer, in particular to a selenium urea formaldehyde roller pelleting compound fertilizer and a production method thereof. After selenium urea formaldehyde is added into the compound fertilizer, agricultural products enriched in selenium cannot only be produced; because a nitrogen element and a selenium element in the selenium urea formaldehyde are chelated, the selenium urea formaldehyde roller pelleting compound fertilizer has a certain release function, and the fertilizer efficacy time is long so as to improve the yield of the crops. On the other hand, the compound fertilizer adopts circulation cooling in the production process and the cooling process, so that fertilizer particles are fully cooled, along with the adhesion of the selenium urea formaldehyde, so that the particle hardness of the compound fertilizer product is high, less water content is introduced into the production without drying, so as to greatly save energy sources.

Description

technical field [0001] The invention relates to a fertilizer, in particular to a selenourea-formaldehyde roller granulated compound fertilizer and a production method thereof. Background technique [0002] In the current technical field of producing chemical compound fertilizers, in addition to nitrogen, phosphorus, and potassium, common whole-element fertilizers also contain trace elements such as zinc, copper, boron, and molybdenum, but they do not contain selenium, so they cannot produce selenium-enriched fertilizers. of agricultural products. As we all know, selenium is an indispensable trace element for human life activities. It is an important component of glutathione peroxidase, an antioxidant in red blood cells. Sufficient selenium can promote glutathione peroxidase to effectively convert hydrogen peroxide into water in the human body; selenium is also the dismutation of peroxide Components of enzymes, which can eliminate free radicals and maintain normal levels of...
